Omicron is supercharging the COVID vaccine booster debate- The data are growing that booster jabs enhance protection ? but their durability, impact and ability to quash the new variant are unknown. E Dolgin, December 2, 2021 ![]() ![]() |
Use of Pfizer-BioNTech COVID-19 Vaccine in Persons Aged ?16 Years: Recommendations of the Advisory Committee on Immunization Practices ? United States, September 2021 K Dooling et al, MMWR, September 21, 2021 ![]()
On August 30, 2021,?after a systematic review of the data,?the Advisory Committee on Immunization Practices revised its interim recommendation to a standard recommendation for use of the Pfizer-BioNTech?COVID-19 vaccine in persons aged =16 years for the prevention of COVID-19. Continued use of the Pfizer-BioNTech COVID-19 vaccine, now fully approved by the FDA in persons aged =16 years, is recommended based on increased certainty that its benefits (prevention of asymptomatic infection, COVID-19, and associated hospitalization and death) outweigh vaccine-associated risks.

Outbreak of SARS-CoV-2 B.1.617.2 (Delta) Variant Infections Among Incarcerated Persons in a Federal Prison ? Texas, July?August 2021 LM Hagan et al, MMWR, September 21, 2021 ![]()
During a COVID-19 outbreak involving the Delta variant in a highly vaccinated incarcerated population, transmission rates were high, even among vaccinated persons. Although attack rates, hospitalizations, and deaths were higher among unvaccinated than among vaccinated persons, duration of positive serial test results was similar for both groups. Infectious virus was cultured from vaccinated and unvaccinated infected persons.

Can immune responses predict which vaccines work best? J Cohen, Science, July 9, 2021 ![]() ![]() |
Networks of SARS-CoV-2 transmission M Cevik et al, Science, July 9, 2021 ![]()
The focus of COVID-19 response strategies has often been on behavior change as a primary means of decreasing contact networks and thus transmission chains. However, contact patterns are driven, in large part, by socioeconomic inequities and structural racism and are nonmodifiable at the individual level in the absence of specific support.

The quest to find genes that drive severe COVID E Callaway, Nature, July 8, 2021 ![]()
Since last March, research teams around the world have scoured the genomes of more than 100,000 people with COVID-19, hoping to find genetic clues to who will be hit hardest by an infection with the virus SARS-CoV-2. What?s emerged from this effort is a dozen or so genetic variants that have a strong statistical association with a person?s chances of developing COVID-19 and becoming gravely ill with the disease.

SARS-CoV-2 Variants and Vaccines PR Krause et al, NEJM, July 7, 2021 ![]() ![]()
Viral variants of concern may emerge with dangerous resistance to the immunity generated by the current vaccines to prevent coronavirus disease 2019 (Covid-19). Moreover, if some variants of concern have increased transmissibility or virulence, the importance of efficient public health measures and vaccination programs will increase. The global response must be both timely and science based.

Infection and Vaccine-Induced Neutralizing-Antibody Responses to the SARS-CoV-2 B.1.617 Variants BV Edara et al, NEJM, July 7, 2021 ![]() ![]()
Our results show that the B.1.617.1 variant was 6.8 times less susceptible, and the B.1.617.2 variant was 2.9 times less susceptible, to neutralization by serum from persons who had recovered from Covid-19 and from vaccinated persons than was the WA1/2020 variant. Despite this finding, a majority of the convalescent serum samples (79% [19 of 24 samples] against B.1.617.1 and 96% [23 of 24 samples] against B.1.617.2) and all serum samples from vaccinated persons still had detectable neutralizing activity above the threshold of detection against both variants through 3 months after infection or after the second dose of vaccine.

Delta Is Now The Dominant Coronavirus Variant In The U.S. J Greenhalgh et al, NPR, July 6, 2021 ![]()
The highly contagious delta variant now accounts for more than 51% of COVID-19 cases in the U.S., according to new estimates released by the Centers for Disease Control and Prevention. The variant, also known as B.1.617.2, was first detected in India and is spreading quickly across the globe.
