Lyu Y , Choong A , Chow EPF , Seib KL , Marshall HS , Unemo M , de Voux A , Wang B , Miranda AE , Gottlieb SL , Mello MB , Wi T , Baggaley R , Marshall C , Abu-Raddad LJ , Abara WE , Chen XS , Ong JJ . Vaccine 2023 Neisseria gonorrhoeae infection (gonorrhoea) is a global public health challenge, causing substantial sexual and reproductive health consequences, such as infertility, pregnancy complications and increased acquisition or transmission of HIV. There is an urgency to controlling gonorrhoea because of increasing antimicrobial resistance to ceftriaxone, the last remaining treatment option, and the potential for gonorrhoea to become untreatable. No licensed gonococcal vaccine is available. Mounting observational evidence suggests that N. meningitidis serogroup B outer membrane vesicle-based vaccines may induce cross-protection against N. gonorrhoeae (estimated 30%-40% effectiveness using the 4CMenB vaccine). Clinical trials to determine the efficacy of the 4CMenB vaccine against N. gonorrhoeae are underway, as are Phase 1/2 studies of a new gonococcal-specific vaccine candidate. Ultimately, a gonococcal vaccine must be accessible, affordable and equitably dispensed, given that those most affected by gonorrhoea are also those who may be most disadvantaged in our societies, and most cases are in less-resourced settings. This vaccine value profile (VVP) provides a high level, holistic assessment of the current data to inform the potential public health, economic and societal value of pipeline vaccines. This was developed by a working group of subject matter experts from academia, non-profit organizations, public private partnerships and multi-lateral organizations. All contributors have extensive expertise on various elements of the N. gonorrhoeae VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using published data obtained from peer-reviewed journals or reports. |

JAMA Netw Open 2022 5 (10) e2237689 IMPORTANCE: Although child mortality trends have decreased worldwide, deaths among children younger than 5 years of age remain high and disproportionately circumscribed to sub-Saharan Africa and Southern Asia. Tailored and innovative approaches are needed to increase access, coverage, and quality of child health care services to reduce mortality, but an understanding of health system deficiencies that may have the greatest impact on mortality among children younger than 5 years is lacking. OBJECTIVE: To investigate which health care and public health improvements could have prevented the most stillbirths and deaths in children younger than 5 years using data from the Child Health and Mortality Prevention Surveillance (CHAMPS) network. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used longitudinal, population-based, and mortality surveillance data collected by CHAMPS to understand preventable causes of death. Overall, 3390 eligible deaths across all 7 CHAMPS sites (Bangladesh, Ethiopia, Kenya, Mali, Mozambique, Sierra Leone, and South Africa) between December 9, 2016, and December 31, 2021 (1190 stillbirths, 1340 neonatal deaths, 860 infant and child deaths), were included. Deaths were investigated using minimally invasive tissue sampling (MITS), a postmortem approach using biopsy needles for sampling key organs and fluids. MAIN OUTCOMES AND MEASURES: For each death, an expert multidisciplinary panel reviewed case data to determine the plausible pathway and causes of death. If the death was deemed preventable, the panel identified which of 10 predetermined health system gaps could have prevented the death. The health system improvements that could have prevented the most deaths were evaluated for each age group: stillbirths, neonatal deaths (aged <28 days), and infant and child deaths (aged 1 month to <5 years). RESULTS: Of 3390 deaths, 1505 (44.4%) were female and 1880 (55.5%) were male; sex was not recorded for 5 deaths. Of all deaths, 3045 (89.8%) occurred in a healthcare facility and 344 (11.9%) in the community. Overall, 2607 (76.9%) were deemed potentially preventable: 883 of 1190 stillbirths (74.2%), 1010 of 1340 neonatal deaths (75.4%), and 714 of 860 infant and child deaths (83.0%). Recommended measures to prevent deaths were improvements in antenatal and obstetric care (recommended for 588 of 1190 stillbirths [49.4%], 496 of 1340 neonatal deaths [37.0%]), clinical management and quality of care (stillbirths, 280 [23.5%]; neonates, 498 [37.2%]; infants and children, 393 of 860 [45.7%]), health-seeking behavior (infants and children, 237 [27.6%]), and health education (infants and children, 262 [30.5%]). CONCLUSIONS AND RELEVANCE: In this cross-sectional study, interventions prioritizing antenatal, intrapartum, and postnatal care could have prevented the most deaths among children younger than 5 years because 75% of deaths among children younger than 5 were stillbirths and neonatal deaths. Measures to reduce mortality in this population should prioritize improving existing systems, such as better access to antenatal care, implementation of standardized clinical protocols, and public education campaigns. |
Gonococcal vaccines: Public health value and preferred product characteristics; report of a WHO global stakeholder consultation, January 2019
Gottlieb SL , Ndowa F , Hook EW3rd , Deal C , Bachmann L , Abu-Raddad L , Chen XS , Jerse A , Low N , MacLennan CA , Petousis-Harris H , Seib KL , Unemo M , Vincent L , Giersing BK . Vaccine 2020 38 (28) 4362-4373 Renewed interest in developing vaccines against Neisseria gonorrhoeae has been sparked by the increasing threat of gonococcal antimicrobial resistance (AMR) and growing optimism that gonococcal vaccines are biologically feasible. Evidence suggests serogroup B Neisseria meningitidis vaccines might provide some cross-protection against N. gonorrhoeae, and new gonococcal vaccine candidates based on several approaches are currently in preclinical development. To further stimulate investment and accelerate development of gonococcal vaccines, greater understanding is needed regarding the overall value that gonococcal vaccines might have in addressing public health and societal goals in low-, middle-, and high-income country contexts and how future gonococcal vaccines might be accepted and used, if available. In January 2019, the World Health Organization (WHO) convened a multidisciplinary international group of experts to lay the groundwork for understanding the potential health, economic, and societal value of gonococcal vaccines and their likely acceptance and use, and for developing gonococcal vaccine preferred product characteristics (PPCs). WHO PPCs describe preferences for vaccine attributes that would help optimize vaccine value and use in meeting the global public health need. This paper describes the main discussion points and conclusions from the January 2019 meeting of experts. Participants emphasized the need for vaccines to control N. gonorrhoeae infections with the ultimate goals of preventing adverse sexual and reproductive health outcomes (e.g., infertility) and reducing the impact of gonococcal AMR. Meeting participants also discussed important PPC considerations (e.g., vaccine indications, target populations, and potential immunization strategies) and highlighted crucial research and data needs for guiding the value assessment and PPCs for gonococcal vaccines and advancing gonococcal vaccine development. |
National Public Health Institute Legal Framework: A tool to build public health capacity
Rosenfeld EL , Binder S , Brush CA , Whitney EAS , Jarvis D , Seib K , Verani AR , Flores MA , Menon AN . Health Secur 2020 18 S43-s52 As countries face public health emergencies, building public health capacity to prevent, detect, and respond to threats is a priority. In recent years, national public health institutes (NPHIs) have emerged to play a critical role in strengthening public health systems and to accelerate and achieve implementation of the International Health Regulations (IHR 2005). NPHIs are science-based government institutions that provide national leadership and expertise for the country's efforts to protect and improve health. Providing a Legal Framework for a National Public Health Institute is a recently released Africa CDC publication intended to support NPHI development throughout Africa. Here we present a legal mapping analysis of sampled legal domains for 5 countries, using the "Menu of Considerations for an NPHI Legal Framework." The analysis delineates the types of legal authorities countries may use to establish or enhance NPHIs and demonstrates how legal mapping can be used to review legal instruments for NPHIs. It also demonstrates variability among legal approaches countries take to establish and enable public health functions for NPHIs. This article examines how the legal framework and menu of considerations can help countries understand the nuances around creating and implementing the laws that will govern their organizations and how countries can better engage stakeholders to identify or address potential areas for opportunity where law may be used as a tool to strengthen public health infrastructure. |
Genetic Similarity of Gonococcal Homologs to Meningococcal Outer Membrane Proteins of Serogroup B Vaccine.
Marjuki H , Topaz N , Joseph SJ , Gernert KM , Kersh EN , Wang X . mBio 2019 10 (5) The human pathogens Neisseria gonorrhoeae and Neisseria meningitidis share high genome identity. Retrospective analysis of surveillance data from New Zealand indicates the potential cross-protective effect of outer membrane vesicle (OMV) meningococcal serogroup B vaccine (MeNZB) against N. gonorrhoeae A licensed OMV-based MenB vaccine, MenB-4C, consists of a recombinant FHbp, NhbA, NadA, and the MeNZB OMV. Previous work has identified several abundantly expressed outer membrane proteins (OMPs) as major components of the MenB-4C OMV with high sequence similarity between N. gonorrhoeae and N. meningitidis, suggesting a mechanism for cross-protection. To build off these findings, we performed comparative genomic analysis on 970 recent N. gonorrhoeae isolates collected through a U.S surveillance system against N. meningitidis serogroup B (NmB) reference sequences. We identified 1,525 proteins that were common to both Neisseria species, of which 57 proteins were predicted to be OMPs using in silico methods. Among the MenB-4C antigens, NhbA showed moderate sequence identity (73%) to the respective gonococcal homolog, was highly conserved within N. gonorrhoeae, and was predicted to be surface expressed. In contrast, the gonococcal FHbp was predicted not to be surface expressed, while NadA was absent in all N. gonorrhoeae isolates. Our work confirmed recent observations (E. A. Semchenko, A. Tan, R. Borrow, and K. L. Seib, Clin Infect Dis, 2018, https://doi.org/10.1093/cid/ciy1061) and describes homologous OMPs from a large panel of epidemiologically relevant N. gonorrhoeae strains in the United States against NmB reference strains. Based on our results, we report a set of OMPs that may contribute to the previously observed cross-protection and provide potential antigen targets to guide the next steps in gonorrhea vaccine development.IMPORTANCE Gonorrhea, a sexually transmitted disease, causes substantial global morbidity and economic burden. New prevention and control measures for this disease are urgently needed, as strains resistant to almost all classes of antibiotics available for treatment have emerged. Previous reports demonstrate that cross-protection from gonococcal infections may be conferred by meningococcal serogroup B (MenB) outer membrane vesicle (OMV)-based vaccines. Among 1,525 common proteins shared across the genomes of both N. gonorrhoeae and N. meningitidis, 57 proteins were predicted to be surface expressed (outer membrane proteins [OMPs]) and thus preferred targets for vaccine development. The majority of these OMPs showed high sequence identity between the 2 bacterial species. Our results provide valuable insight into the meningococcal antigens present in the current OMV-containing MenB-4C vaccine that may contribute to cross-protection against gonorrhea and may inform next steps in gonorrhea vaccine development. |
Evaluation of educational interventions to enhance adolescent specific vaccination coverage
Underwood NL , Gargano LM , Sales J , Vogt TM , Seib K , Hughes JM . J Sch Health 2019 89 (8) 603-611 BACKGROUND: In this study, we assessed impact of two educational interventions designed to increase coverage of three vaccines recommended during adolescence among Georgia middle and high school students (tetanus diphtheria pertussis [Tdap], meningococcal [MenACWY], and human papillomavirus [HPV] vaccines). METHODS: We randomized 11 middle and high schools in one school district into one of three arms: (1) control; (2) educational intervention for parents only (P only); and (3) multicomponent educational intervention for parents and adolescents (P + A), which consisted of educational brochures for parents about vaccines recommended during adolescence and a vaccine-focused curriculum delivered to adolescents by science teachers. We obtained vaccination coverage data during intervention years from the state immunization registry. RESULTS: Odds of receiving at least one vaccine during the study were higher among adolescents in P + A arm compared to control (Odds Ratio [OR]: 1.4; 95% Confidence Interval [CI]: 1.1-2.0). Adolescents in P + A arm had greater odds of receiving at least one vaccine compared with those in P only arm (OR: 1.4; 95% CI: 1.1-1.7). CONCLUSIONS: A multicomponent educational intervention for adolescents and parents increased adolescent vaccination uptake. Results suggest similar interventions can increase awareness and demand for vaccines among parents and adolescents. |
Policy making for vaccine use as a driver of vaccine innovation and development in the developed world
Seib K , Pollard AJ , de Wals P , Andrews RM , Zhou F , Hatchett RJ , Pickering LK , Orenstein WA . Vaccine 2017 35 (10) 1380-1389 In the past 200years, vaccines have had unmistakable impacts on public health including declines in morbidity and mortality, most markedly in economically-developed countries. Highly engineered vaccines including vaccines for conditions other than infectious diseases are expected to dominate future vaccine development. We examine immunization vaccine policy as a driver of vaccine innovation and development. The pathways to recommendation for use of licensed vaccines in the US, UK, Canada and Australia have been similar, including: expert review of disease epidemiology, disease burden and severity; vaccine immunogenicity, efficacy and safety; programmatic feasibility; public demand; and increasingly cost-effectiveness. Other attributes particularly important in development of future vaccines are likely to include: duration of immunity for improved vaccines such as pertussis; a greater emphasis on optimizing community protection rather than direct protection only; programmatic implementation, feasibility, improvements (as in the case of development of a universal influenza vaccine); public concerns/confidence/fears related to outbreak pathogens like Ebola and Zika virus; and major societal burden for combating hard to treat diseases like HIV and antimicrobial resistant pathogens. Driving innovation and production of future vaccines faces enormous economic hurdles as available approaches, technologies and regulatory pathways become more complex. As such, cost-mitigating strategies and focused, aligned efforts (by governments, private organizations, and private-public partnerships) will likely be needed to continue to spur major advances in vaccine technologies and development. |

Orenstein WA , Gellin BG , Beigi RH , Despres S , Lynfield R , Maldonado Y , Mouton C , Rawlins W , Rothholz MC , Smith N , Thompson K , Torres C , Viswanath K , Hosbach P , Despres S , Rawlins W , Orenstein WA , Beigi RH , Hosbach P , Rothholz MC , Viswanath K , Bobo N , Brewer NT , Eckert L , Etkind P , Kahn JA , Loehr J , Martin K , Morita J , Salisbury D , Saslow D , Tan L , Turner JC , Willoughby RE Jr , Borden V , Croyle R , Deal CD , Gold R , Hance MBE , Hess MA , Lee NC , Lowy D , Stokley S , Wharton M , Bergquist S , Bok K , Gellin BG , Seib K , Zettle M . Public Health Rep 2016 131 (1) 17-25 An average of 25,900 cases of human papillomavirus (HPV)-associated cancers are newly diagnosed in the United States each year.1,2 An estimated 14 million people are newly infected with HPV each year, and nearly half of these infections occur in people aged 14–25 years.3 Although most infections resolve over time, persistent infection with oncogenic HPV types is associated with a variety of cancers. Virtually all cervical cancers are caused by HPV, along with 90% of anal, 69% of vaginal, 60% of oropharyngeal, 51% of vulvar, and 40% of penile cancers.1 Furthermore, 87% of anal, 76% of cervical, 60% of oropharyngeal, 55% of vaginal, 44% of vulva, and 29% of penile cancers are caused by oncogenic HPV type 16 or 18.4 Of the 35,000 HPV cancers reported in 2009 in the United States, 39% occurred in males.1 | Three HPV vaccines are currently available in the United States. One is a bivalent vaccine (designated as HPV2) designed to protect against HPV types 16 and 18, which are responsible for the most HPV-associated cancers. One is a quadrivalent vaccine (HPV4), which protects against HPV types 16 and 18 and two additional types, 6 and 11, that are the most common causes of genital warts. One is a nonavalent vaccine (HPV9) that protects against HPV types 6, 11, 16, and 18, and offers additional protection against five oncogenic HPV types, 31, 33, 45, 52, and 58. To prevent cancers associated with HPV infections, the Advisory Committee on Immunization Practices (ACIP) recommends HPV immunization for all children aged 11 or 12 years with the licensed three-doses series. The ACIP has recommended routine HPV immunization for girls since 2006 and for boys since 2011.2 |
Preexisting chronic health conditions and health insurance status associated with vaccine receipt among adolescents
Seib K , Underwood NL , Gargano LM , Sales JM , Morfaw C , Weiss P , Murray D , Vogt TM , DiClemente RJ , Hughes JM . J Adolesc Health 2015 58 (2) 148-53 PURPOSE: Four vaccines are routinely recommended for adolescents: tetanus, diphtheria, and acellular pertussis (Tdap); human papillomavirus (HPV); meningococcal-conjugate (MCV4); and a yearly seasonal influenza vaccine. Vaccination promotion and outreach approaches may need to be tailored to certain populations, such as those with chronic health conditions or without health insurance. METHODS: In a controlled trial among middle and high school students in Georgia, 11 schools were randomized to one of three arms: no intervention, parent education brochure, or parent education brochure plus a student curriculum on the four recommended vaccines. Parents in all arms were surveyed regarding their adolescent's vaccine receipt, chronic health conditions, and health insurance status. RESULTS: Of the 686 parents, most (91%) reported their adolescent had received at least one of the four vaccines: Tdap (82%), MCV4 (59%), current influenza vaccine (53%) and HPV (48%). Twenty-three percent of parents reported that their adolescent had asthma. Most parents reported that their adolescent's insurance was Medicaid (60%) or private insurance (34%), and 6% reported no insurance. More adolescents with a chronic health condition received any adolescent vaccine than adolescents without a chronic health condition (p < .0001). Among those with no insurance, fewer had received any adolescent vaccine than those with Medicaid or private insurance (p < .0001). CONCLUSIONS: The federal Vaccines for Children program offers recommended vaccines free to eligible children (including those without health insurance). Our findings suggest that parents may not be aware of this program or eligibility for it, thus revealing a need for education or other fixes. |
Preparation for global introduction of inactivated poliovirus vaccine: safety evidence from the US Vaccine Adverse Event Reporting System, 2000-12.
Iqbal S , Shi J , Seib K , Lewis P , Moro PL , Woo EJ , Shimabukuro T , Orenstein WA . Lancet Infect Dis 2015 15 (10) 1175-1182 BACKGROUND: Safety data from countries with experience in the use of inactivated poliovirus vaccine (IPV) are important for the global polio eradication strategy to introduce IPV into the immunisation schedules of all countries. In the USA, IPV has been included in the routine immunisation schedule since 1997. We aimed to analyse adverse events after IPV administration reported to the US Vaccine Adverse Event Reporting System (VAERS). METHODS: We analysed all VAERS data associated with IPV submitted between Jan 1, 2000, and Dec 31, 2012, either as individual or as combination vaccines, for all age and sex groups. We analysed the number and event type (non-serious, non-fatal serious, and death reports) of individual reports, and explored the most commonly coded event terms to describe the adverse event. We classified death reports according to previously published body-system categories (respiratory, cardiovascular, neurological, gastrointestinal, other infectious, and other non-infectious) and reviewed death reports to identify the cause of death. We classified sudden infant death syndrome as a separate cause of death considering previous concerns about sudden infant syndrome after vaccines. We used empirical Bayesian data mining methods to identify disproportionate reporting of adverse events for IPV compared with other vaccines. Additional VAERS data from 1991 to 2000 were analysed to compare the safety profiles of IPV and oral poliovirus vaccine (OPV). FINDINGS: Of the 41 792 adverse event reports submitted, 39 568 (95%) were for children younger than 7 years. 38 381 of the reports for children in this age group (97%) were for simultaneous vaccination with IPV and other vaccines (most commonly pneumococcal and acellular pertussis vaccines), whereas standalone IPV vaccines accounted for 0.5% of all reports. 34 880 reports were for non-serious events (88%), 3905 reports were for non-fatal serious events (10%), and 783 reports were death reports (2%). Injection-site erythema was the most commonly coded term for non-serious events (29%), and pyrexia for non-fatal serious events (38%). Most deaths (96%) were in children aged 12 months or younger; most (52%) had sudden infant death syndrome as the reported cause of death. The safely profiles of combined IPV and whole-cell pertussis vaccines, OPV and whole-cell pertussis vaccines, and OPV and acellular pertussis vaccines were similar. We noted no indication of disproportionate reporting of adverse events after immunisation with IPV-containing vaccines compared with other vaccines between 1990 and 2013. INTERPRETATION: Fairly few adverse events were reported for the more than 250 million IPV doses distributed between 2000 and 2012. Sudden infant death syndrome reports after IPV were consistent with reporting patterns for other vaccines. No new or unexpected vaccine safety problems were identified for fatal, non-fatal serious, and non-serious reports in this assessment of adverse events after IPV. FUNDING: None. |
Combined effects of antenatal receipt of influenza vaccine by mothers and pneumococcal conjugate vaccine receipt by infants: results from a randomized, blinded, controlled trial
Omer SB , Zaman K , Roy E , Arifeen SE , Raqib R , Noory L , Seib K , Breiman RF , Steinhoff MC . J Infect Dis 2013 207 (7) 1144-7 A 2 x 2 factorial trial was performed to determine the efficacy of antennal influenza vaccination of mothers plus pneumococcal conjugate vaccination of their infants against respiratory illness during early infancy. The efficacy of trivalent inactivated influenza vaccine (TIV; delivered to mothers) plus 7-valent pneumococcal vaccine (PCV7; delivered to infants) was higher than the efficacy of TIV alone or PCV7 alone. During the period of the study in which influenza was circulating, the efficacy of TIV plus PCV7 was 72.4% (95% confidence interval, 30.2%-89.1%) against febrile respiratory illness and 66.4% (95% CI, 14.3%-86.9%) against medically attended acute respiratory illness.

Pandemic 2009 influenza A(H1N1) virus illness among pregnant women in the United States
Siston AM , Rasmussen SA , Honein MA , Fry AM , Seib K , Callaghan WM , Louie J , Doyle TJ , Crockett M , Lynfield R , Moore Z , Wiedeman C , Anand M , Tabony L , Nielsen CF , Waller K , Page S , Thompson JM , Avery C , Springs CB , Jones T , Williams JL , Newsome K , Finelli L , Jamieson DJ . JAMA 2010 303 (15) 1517-25 CONTEXT: Early data on pandemic 2009 influenza A(H1N1) suggest pregnant women are at increased risk of hospitalization and death. OBJECTIVE: To describe the severity of 2009 influenza A(H1N1) illness and the association with early antiviral treatment among pregnant women in the United States. DESIGN, SETTING, AND PATIENTS: Surveillance of 2009 influenza A(H1N1) in pregnant women reported to the Centers for Disease Control and Prevention (CDC) with symptom onset from April through December 2009. MAIN OUTCOME MEASURES: Severity of illness (hospitalizations, intensive care unit [ICU] admissions, and deaths) due to 2009 influenza A(H1N1) among pregnant women, stratified by timing of antiviral treatment and pregnancy trimester at symptom onset. RESULTS: We received reports on 788 pregnant women in the United States with 2009 influenza A(H1N1) with symptom onset from April through August 2009. Among those, 30 died (5% of all reported 2009 influenza A[H1N1] influenza deaths in this period). Among 509 hospitalized women, 115 (22.6%) were admitted to an ICU. Pregnant women with treatment more than 4 days after symptom onset were more likely to be admitted to an ICU (56.9% vs 9.4%; relative risk [RR], 6.0; 95% confidence interval [CI], 3.5-10.6) than those treated within 2 days after symptom onset. Only 1 death occurred in a patient who received treatment within 2 days of symptom onset. Updating these data with the CDC's continued surveillance of ICU admissions and deaths among pregnant women with symptom onset through December 31, 2009, identified an additional 165 women for a total of 280 women who were admitted to ICUs, 56 of whom died. Among the deaths, 4 occurred in the first trimester (7.1%), 15 in the second (26.8%), and 36 in the third (64.3%); CONCLUSIONS: Pregnant women had a disproportionately high risk of mortality due to 2009 influenza A(H1N1). Among pregnant women with 2009 influenza A(H1N1) influenza reported to the CDC, early antiviral treatment appeared to be associated with fewer admissions to an ICU and fewer deaths. |
