#COVID-19 vaccine

A mathematical technique called matrix completion could speed up the development of vaccines for flu and COVID-19 variants.

Biden may not have used the right word when he described the pandemic as “over,” but things are trending in the right direction.

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.

The technology used to create COVID-19 vaccines may also help fight cancer.

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 engineered protein vaccine was highly effective in a clinical trial but faced a long delay for authorization.

Fauci led the U.S. HIV research effort for nearly 40 years before becoming the nation’s leading COVID-19 medical advisor.

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.

After a long wait, the FDA authorizes Pfizer and Moderna vaccines for children as young as 6 months old.

Vaccines designed to produce a strong T cell response may help protect against current and future SARS-CoV-2 variants.

Extra vaccine doses, monoclonal antibodies and antivirals can help prevent severe illness.

Approximately 1 in 3 Americans 65 and older who completed their initial vaccination round still have not received a first booster shot.

People diagnosed with cancer over a year ago and those who were not on treatment did not have a higher risk of hospitalization or death.
