Perez-Vilar S , Dores GM , Marquez PL , Ng CS , Cano MV , Rastogi A , Lee L , Su JR , Duffy J . Vaccine 2021 40 (2) 247-254 ![]() ![]() BACKGROUND: Bexsero® (GlaxoSmithKline) is a four-component Neisseria meningitidis serogroup B vaccine (MenB-4C). It was licensed in the United States in 2015 for use among individuals ages 10-25 years. We aimed to assess the post-licensure safety profile of MenB-4C by examining reports received in the Vaccine Adverse Event Reporting System (VAERS). METHODS: VAERS is a national passive surveillance system for adverse events (AEs) following immunization that uses the Medical Dictionary for Regulatory Activities to code reported AEs and the Code of Federal Regulations to classify reports by seriousness. In this case series, we analyzed U.S. reports involving MenB-4C received between January 23, 2015 through December 31, 2018. We used Empirical Bayesian data mining to identify MenB-4C/AE combinations reported at least twice as often as expected. RESULTS: VAERS received 1,867 reports following MenB-4C administration, representing 332 reports per million doses distributed. Most reports were for females (59%), with a median age of 17 years (interquartile range: 16-18 years); 40% of reports described simultaneous administration of other vaccines. The majority of reports were classified as non-serious (96%). The most commonly reported AEs were injection site pain (22%), pyrexia (16%), and headache (16%). Data mining identified disproportionate reporting for "injected limb mobility decreased" secondary to injection site reactions, including extensive swelling of the vaccinated limb and injection site pain. CONCLUSIONS: Analysis of passive surveillance data from over 5.6 million doses of MenB-4C distributed in the United States did not reveal new safety concerns. The large majority of reports were classified as non-serious and the reported AEs were generally consistent with the safety experience described in clinical studies and the product's package insert. While our results are reassuring, continued post-marketing surveillance is warranted. |
Adverse events following quadrivalent meningococcal diphtheria toxoid conjugate vaccine (Menactra®) reported to the Vaccine Adverse Event Reporting System (VAERS), 2005-2016.
Myers TR , McNeil MM , Ng CS , Li R , Marquez PL , Moro PL , Omer SB , Cano MV . Vaccine 2020 38 (40) 6291-6298 ![]() ![]() BACKGROUND: Post marketing safety evaluations of quadrivalent meningococcal diphtheria-toxoid conjugate vaccine (MenACWY-D) have focused on post-vaccination risk of Guillain Barré syndrome (GBS), adverse events (AEs) after maternal vaccination, and comparative studies with the newer quadrivalent meningococcal CRM(197) conjugate vaccine (MenACWY-CRM). To provide an updated general safety assessment, we reviewed reports of AEs following MenACWY-D submitted to the Vaccine Adverse Event Reporting System (VAERS). METHODS: VAERS is a national spontaneous reporting vaccine safety surveillance system co-administered by the Centers for Disease Control and Prevention and the U.S. Food and Drug Administration. We searched the VAERS database for U.S. reports of AEs after administration of MenACWY-D from January 2005 through June 2016. We conducted clinical reviews of serious reports after MenACWY-D administered alone, reports of MenACWY-D use during pregnancy, and reports of selected pre-specified outcomes. We screened for disproportionate reporting of AEs after MenACWY-D using empirical Bayesian data mining. RESULTS: VAERS received 13,075 U.S. reports after receipt of MenACWY-D; most (86%) described vaccination in adolescents, were classified as non-serious (94%), and described AEs consistent with pre-licensure studies. We did not find any evidence that reported deaths were related to vaccination. In serious reports, GBS and meningococcal infection were the most commonly reported medical conditions. Many reports of MenACWY-D use during pregnancy described inadvertent vaccination; most (61%) did not report any AE. CONCLUSIONS: Findings from our comprehensive review of reports to VAERS following MenACWY-D are consistent with data from pre-licensure studies and provide further reassurance on the safety of MenACWY-D. |
Erythema multiforme, Stevens Johnson syndrome, and toxic epidermal necrolysis reported after vaccination, 1999-2017.
Su JR , Haber P , Ng CS , Marquez PL , Dores GM , Perez-Vilar S , Cano MV . Vaccine 2019 38 (7) 1746-1752 ![]() ![]() BACKGROUND: Since the last review of vaccine safety surveillance data for erythema multiforme (EM), Stevens Johnson syndrome (SJS), SJS/TEN, and toxic epidermal necrolysis (TEN) (EM/SJS/TEN), over 37 new vaccines have been introduced in the United States. We sought to describe reported EM/SJS/TEN after vaccines during 1999-2017. METHODS: We identified U.S. reports of EM/SJS/TEN received by the Vaccine Adverse Event Reporting System (VAERS) during 1999-2017. We stratified analysis by condition (EM, SJS, or TEN), and analyzed reports by serious or non-serious status, sex, age group, time from vaccination to symptom onset, exposure to known causes of EM/SJS/TEN, and vaccines administered. We used Empirical Bayesian data mining to detect vaccine-AE pairs reported more frequently than expected. RESULTS: Of 466,027 reports to VAERS during 1999-2017, we identified 984 reports of EM, 89 reports of SJS, 6 reports of SJS/TEN, and 7 reports of TEN. Few reports of EM (9%), and most reports of SJS (52%), SJS/TEN (100%), and TEN (100%) were serious. Overall, 55% of reports described males, 48% described children aged < 4 years; 58% of EM/SJS/TEN occurred </= 7 days after vaccination. Few reports (</=5%) described exposure to known causes of EM/SJS/TEN. Overall, childhood vaccines (e.g., combined measles, mumps, and rubella vaccine) were most commonly reported. We identified 6 deaths; 4 were exposed to medications associated with EM/SJS/TEN. EM after smallpox vaccine was reported disproportionately among people aged 19-49 years. CONCLUSIONS: EM/SJS/TEN were rarely reported after vaccination; data mining identified a known association between EM and smallpox vaccine. |
Reports of atypical shoulder pain and dysfunction following inactivated influenza vaccine, Vaccine Adverse Event Reporting System (VAERS), 2010-2017
Hibbs BF , Ng CS , Museru O , Moro PL , Marquez P , Woo EJ , Cano MV , Shimabukuro TT . Vaccine 2019 38 (5) 1137-1143 BACKGROUND: Vaccines administered into or too close to underlying joint structures have the potential to cause shoulder injuries. Limited data exist on the epidemiology of such events. OBJECTIVE: To describe case reports of atypical shoulder pain and dysfunction following injection of inactivated influenza vaccine (IIV). METHODS: We searched the Vaccine Adverse Event Reporting System (VAERS) database from July 2010 to June 2017 for reports of atypical shoulder pain and dysfunction following IIV. When identifying reports, we made no assumptions about true incident injury or causality with respect to vaccination. Pain had to begin <48 h after vaccination and signs and symptoms had to continue for >7 days to differentiate from self-limited local reactions. We conducted descriptive analysis. RESULTS: We identified 1220 reports that met our case definition (2.0% of all IIV reports, range 1.5%-2.5% across influenza seasons). Median age was 52 years (range 16-94) and most patients (82.6%) were female. Shoulder pain (44.1%), injected limb mobility decreased (40.8%), joint range of motion decreased (21.2%), rotator cuff syndrome (9.2%), and bursitis (9.0%) were frequently reported. In 86.6% of reports, signs and symptoms had not resolved by the time of report submission. In reports that included descriptions suggesting contributing factors (n = 266), vaccination given "too high" on the arm was cited in 81.2%. Nearly half (n = 605, 49.6%) of reports described a healthcare provider evaluation. Treatments included non-narcotic analgesics, physical therapy, and corticosteroid injection. Vaccinations were most commonly administered in a pharmacy or retail store (41.0%) or doctor's office or hospital (31.6%). CONCLUSIONS: Reports of atypical shoulder pain and dysfunction following IIV were uncommon, considering the amount of IIV use, and stable across influenza seasons. While specific etiology of cases is unknown, improperly administered vaccine, which is preventable, might be a factor. Prevention strategies include education, training, and adherence to best practices for vaccine administration. |
Postlicensure safety surveillance of recombinant Zoster vaccine (Shingrix) - United States, October 2017-June 2018
Hesse EM , Shimabukuro TT , Su JR , Hibbs BF , Dooling KL , Goud R , Lewis P , Ng CS , Cano MV . MMWR Morb Mortal Wkly Rep 2019 68 (4) 91-94 Recombinant zoster vaccine (RZV; Shingrix), an adjuvanted glycoprotein vaccine, was licensed by the Food and Drug Administration (FDA) and recommended by the Advisory Committee on Immunization Practices for adults aged >/=50 years in October 2017 (1). The previously licensed live-attenuated zoster vaccine (ZVL; Zostavax) is recommended for adults aged >/=60 years. RZV is administered intramuscularly as a 2-dose series, with an interval of 2-6 months between doses. In prelicensure clinical trials, 85% of 6,773 vaccinated study participants reported local or systemic reactions after receiving RZV, with approximately 17% experiencing a grade 3 reaction (erythema or induration >3.5 inches or systemic symptoms that interfere with normal activity). However, rates of serious adverse events (i.e., hospitalization, prolongation of existing hospitalization, life-threatening illness, permanent disability, congenital anomaly or birth defect, or death) were similar in the RZV and placebo groups (2). After licensure, CDC and FDA began safety monitoring of RZV in the Vaccine Adverse Event Reporting System (VAERS) (3). During the first 8 months of use, when approximately 3.2 million RZV doses were distributed (GlaxoSmithKline, personal communication, 2018), VAERS received a total of 4,381 reports of adverse events, 130 (3.0%) of which were classified as serious. Commonly reported signs and symptoms included pyrexia (fever) (1,034; 23.6%), injection site pain (985; 22.5%), and injection site erythema (880; 20.1%). No unexpected patterns were detected in reports of adverse events or serious adverse events. Findings from early monitoring of RZV are consistent with the safety profile observed in prelicensure clinical trials. |
Adverse events following quadrivalent meningococcal CRM-conjugate vaccine (Menveo®) reported to the Vaccine Adverse Event Reporting system (VAERS), 2010-2015.
Myers TR , McNeil MM , Ng CS , Li R , Lewis PW , Cano MV . Vaccine 2017 35 (14) 1758-1763 ![]() ![]() BACKGROUND: Limited data are available describing the post-licensure safety of meningococcal vaccines, including Menveo(R). We reviewed reports of adverse events (AEs) to the Vaccine Adverse Event Reporting System (VAERS) to assess safety in all age groups. METHODS: VAERS is a national spontaneous vaccine safety surveillance system co-administered by the Centers for Disease Control and Prevention and the US Food and Drug Administration. We searched the VAERS database for US reports of adverse events in persons who received Menveo from 1 January 2010 through 31 December 2015. We clinically reviewed reports and available medical records for serious AEs, selected pre-specified outcomes, and vaccination during pregnancy. We used empirical Bayesian data mining to identify AEs that were disproportionately reported after receipt of Menveo. RESULTS: During the study period, VAERS received 2614 US reports after receipt of Menveo. Of these, 67 were classified as serious, including 1 report of death. Adolescents (aged 11-18years) accounted for 74% of reports. Most of the reported AEs were non-serious and described AEs consistent with data from pre-licensure studies. Anaphylaxis and syncope were the two most common events in the serious reports. We did not identify any new safety concerns after review of AEs that exceeded the data mining threshold, although we did observe disproportionate reporting for terms that were not associated with an adverse event (e.g., "incorrect drug dosage form administered", "wrong technique in drug usage process"). Although reports were limited, we did not find any evidence for concern regarding the use of Menveo during pregnancy. CONCLUSIONS: In our review of VAERS reports, findings of AEs were consistent with the data from pre-licensure studies. Vaccine providers should continue to emphasize and adhere to proper administration of the vaccine. |
