CDC Director Rochelle Walensky has signed off on updated versions of the Moderna and Pfizer-BioNTech vaccines that target the original virus and the omicron subvariants.

The FDA is authorizing new booster shots to protect people against another surge of omicron infections this fall and winter.

The Food and Drug Administration authorized the first updated COVID-19 vaccines since the pandemic began — boosters targeted at the omicron variant.

The new shots from Moderna and Pfizer-BioNTech target both the original strain of the coronavirus and the omicron BA.4/BA.5 subvariants that most people are catching now.

The Food and Drug Administration is planning to authorize a new generation of COVID-19 boosters this week that for the first time will target the omicron variant.

Some scientists are alarmed that the agency plans to evaluate the next generation of boosters by reviewing mouse studies alone. Others say there's no time to waste waiting for human trials.

The Food and Drug Administration's decision against allowing more people to get second boosters has left many younger adults in limbo and angry.

The Biden administration is scrapping plans to offer COVID boosters for people under 50 this summer. Instead officials will push for an earlier release of the next generation boosters in the fall.

Evusheld, a course of injected antibodies, helps protect people with weak immune systems for up to six months. The government is making it available through pharmacies and individual providers.

The Biden administration may scrap plans to expand eligibility for second boosters to younger adults. Instead, it's trying to speed up the next generation of boosters targeting the omicron variant.

President Biden's COVID infection underscores a new surge of the pandemic, with another highly contagious virus strain and a federal scramble to provide more boosters to try to protect people.

The Biden administration is considering expanding eligibility for a second COVID-19 booster to those under 50 to try to protect more people against the latest omicron surge.

Dr. Anthony Fauci says he will step down before the end of President Biden's first term, but he has not chosen an exact date and is not sure what he will do after he leaves his position.

COVID vaccine makers are developing new boosters for a fall campaign. But some experts question the FDA's decision to tell companies to make shots against the BA.4/5 subvariants.

With COVID vaccines rolling out for younger children, NPR health correspondent Rob Stein and pediatrician Dr. Nia Heard-Garris are answering listener questions.

FDA advisers recommended the agency authorize new COVID-19 vaccines targeted at omicron to protect people against what could be another winter surge.

The Food and Drug Administration is meeting on Tuesday to make an extremely difficult but important decision: Should vaccines be updated to target the omicron variant?

Centers for Disease Control and Prevention Director Rochelle Walensky has cleared the way for the roll out of vaccines for children five years and under as early as this coming week.

Some scientists estimate that cases of long COVID from omicron will still rise, however, because of high transmissibility and the misconception that people don't have to worry about catching it.

Food and Drug Administration advisers are opening a two-day meeting to review Moderna and Pfizer-BioNTech's COVID-19 vaccines for children, including the first vaccines for kids younger than age 5.
