Vaccine type, older age, male sex and especially smoking were associated with lower antibody responses.

A booster targeting Omicron SARS-CoV-2 variant produced a broader immune response than one targeting variants similar to original strain.

Findings from NIH study offer insight into biological mechanisms, pointing to possible treatments.

Study findings suggest people with chronic liver disease should be prioritized for booster shots.

Current vaccines are effective for preventing severe disease, but a nasal vaccine could potentially prevent infection and transmission.

Herpes, HIV, Epstein-Barr and other viruses hang around, causing potential long-term health woes. Should long COVID surprise us?

NIH-funded study suggests need to boost CD8+ T cell response after infection.

With further development, the gel could provide additional protection against COVID-19 and other respiratory illnesses.

Experts stress the need for targeted efforts to increase vaccine uptake among cancer patients with lower vaccination rates.

Several mechanisms may play a role, including persistent virus and ongoing immune dysregulation.

Researchers encourage additional studies to determine why Black and Latino people experience long COVID symptoms more than white people.

The results suggest that preventing viral infections might reduce the risk for diseases like Alzheimers and multiple sclerosis.

The condition may be caused by hidden viral reservoirs that remain in the body after initial infection.

Increased protection against hospitalization or death was seen regardless of age or history of previous boosters.

While regular boosters may help keep vulnerable people out of the hospital, annual boosters might not be necessary for everyone.
