Latinos have seen a striking decline in COVID deaths while white people account for a larger proportion.
Updated boosters could go to the “worried well” who have good insurance rather than to those at highest risk.
Updated Pfizer-BioNTech and Moderna bivalent boosters contain spike proteins from the original and BA.4 and BA.5 omicron variants.
Whether omicron coronavirus variants cause long COVID symptoms as often—and as severe—as previous variants is a matter of heated study.
The update aims to help the public better protect themselves and understand their risk.
Antibody levels decrease substantially within three months after a booster, according to new clinical trial data.
Vaccines designed to produce a strong T cell response may help protect against current and future SARS-CoV-2 variants.
Approximately 1 in 3 Americans 65 and older who completed their initial vaccination round still have not received a first booster shot.
National Comprehensive Cancer Network encourages second mRNA booster shot and offers COVID PrEP advice for people with cancer.
CoVac-1 induced T-cell responses in about 90% of immunocompromised people with impaired B-cell function.
The quick spread of the BA.2 subvariant is likely due to its greater infectiousness rather than its ability to evade the immune system.
NIAID is preparing for the possibility of future variants evading protection against currently available COVID-19 vaccines.
The benefits of achieving herd immunity thresholds have been less successful with respiratory viruses that continually mutate.
Immunocompromised people ages 12 and older are also eligible for an additional shot.
Protecting the immunocompromised is not only a matter of health equity, it’s critical to ending the pandemic.
Researchers showed that B cells evolve after COVID-19 vaccination to help improve protection against SARS-CoV-2 over time.
