A World Health Organization advisory group said Tuesday it “strongly supports urgent and broad access” to COVID-19 vaccines and boosters, especially for people who face high risks for severe disease.
The CDC contacted pharmacies on Wednesday to reinforce the message that people with moderate to severe immune suppression should receive a fourth COVID-19 vaccine.
A fourth shot of the COVID-19 vaccine boosts antibodies but doesn’t provide enough protection to prevent infections from the Omicron variant, according to new research at an Israeli hospital.
Some Americans with a weakened immune system who face high risks for severe COVID-19 become eligible this week to receive a fourth dose of a coronavirus vaccine.
Booster shot protection against symptomatic COVID-19 caused by the Omicron variant appears to fade in about 10 weeks, according to new data from Britain.
