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.

An experimental vaccine produced an immune response to a range of different coronaviruses in mice and monkeys, including SARS-CoV-2.

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.

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

The nation’s top pandemic adviser joins a growing number of people catching the coronavirus during the omicron wave.

The good news is that only 4% of HIV-positive people experienced COVID breakthrough after vaccination.

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