Step aside, BA.5. The new variants BQ.1 and BQ.1.1, appear to be among the most adept yet at evading immunity from previous infection and vaccination.

Two subvariants that have emerged from the soup of Omicron offspring are among the most adept at evading immunity. They appear poised to become dominant in the U.S. and could fuel a new surge.

Some hospitals are filling up as respiratory infections hits hard and early. It happening just as flu season starts up and another possible COVID-19 wave approaches.

Biden received a new COVID booster as part of the administration's push to increase uptake, but two new research papers cast doubt on whether they are any better than the original vaccines.

SARS-CoV-2 is evolving "rapidly," spawning one new variant after another. But omicron continues to dominate, raising new questions about how evolution of the virus is headed.

The Food and Drug Administration authorized the new bivalent omicron boosters for kids as young as 5 years old. The shots could roll out almost immediately.

Here we go again. The virus is starting to surge in many European countries and there are early signs a wave may be starting in the U.S. too.

The National Federation of Infectious Diseases and the CDC are urging people to get flu shots. Both groups say the flu is likely to come back after a two-year hiatus, and it could be a bad year.

Some flu experts are urging many people to get their shots earlier than usual this year because of the potential for an early, possibly severe flu season. But what's the best timing for you?

Pfzier-BioNTech and Moderna are asking the Food and Drug Administration to authorize the new omicron boosters for young children.

After virtually disappearing for the last two years, there are troubling clues that the flu could come roaring back this year, to cause trouble alongside COVID.

Biden's comments — made as officials try to convince Americans to get a new booster shot and the White House seeks $22 billion in new COVID funding — were "unfortunate," several epidemiologists said.

President Biden says the pandemic "is over," but public health experts, epidemiologists, infectious disease researchers and others strongly disagree, saying his remarks endanger efforts to save lives.

How has the rollout of the new COVID-19 vaccine boosters gone so far? Shots are plentiful, waits are short, but demand is uncertain.

It's a strange moment in the pandemic. For most vaccinated people, the risk of severe illness has gone way down. But hundreds are dying of COVID-19 every day. So how dangerous is the virus now?

They argue the threat posed by COVID has lessened because of preexisting immunity and access to treatment. Plus, some deaths may be incorrectly blamed on COVID. Others caution it's too soon to tell.

The COVID-19 vaccine strategy may be shifting toward Americans getting yearly vaccinations, like many do with annual flu shots.

New COVID-19 vaccine boosters designed to combat recent subvariants of the coronavirus are being made available to people over 12 years old. We have some guidance on who should get one and when.

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.
