The top public health authorities in the Biden administration denounced misinformation about the coronavirus vaccines, following an anti-vaccine rally in Washington, D.C. over the weekend and a falsehood-laden segment on Fox News on Tuesday night that has been widely shared on social media.

"We cannot look past the strain on our health systems and substantial number of deaths," Dr. Rochelle Walensky said.

The rise of omicron has fed the longstanding efforts to pretend vaccines don't reduce the spread. Here's what the data show.

The top health leaders in the U.S. will testify before the Senate on Tuesday about the federal response to the omicron Covid variant, as new infections and hospitalizations reach pandemic highs. The Senate health committee will hear testimony from White House chief medical advisor Dr. Anthony Fauci, Centers for Disease Control and Prevention Director Dr. Rochelle Walensky, and acting Food and Drug Administration Commissioner Dr. Janet Woodcock. Dawn O'Connell, assistant secretary for preparedness and response at the Department of Health and Human Services, is also testifying. The hearing comes as the CDC faces criticism for its public messaging on the pandemic, particularly its quarantine guidance.

Frustrated and exhausted, many Americans say they tune out muddled guidance.

During an appearance on Fox News Sunday, CDC director Rochelle Walensky faltered in explaining how many of the 836,000 U.S. patients whose deaths were attributed to Covid in the last two years had underlying medical conditions.

The rate of hospitalization for kids under five — who are not yet eligible for the vaccine — is the highest since the pandemic began.

Hospitalizations of U.S. children under 5 with COVID-19 have soared to unprecedented levels, a worrisome trend in youngsters too young to be vaccinated.

The move follows the FDA's authorization earlier this week and an hours-long meeting of the CDC's outside advisers.

The CDC endorsement Wednesday means about 5 million of the younger teens who had their last shot in the spring are eligible for a booster right away.

If the CDC approves the advisory panel's recommendation, boosters for adolescents age 12-17 could be available as early as this week. The shots should be given five months after initial immunization.

The recommendation comes amid an increase in pediatric hospitalizations.

The guidelines say people who test positive for COVID-19, but have no symptoms, can leave isolation after five days without testing again.

Cutting the isolation for positive cases to five days could lead to more infections if people don't take masking seriously. A testing requirement, would have made the policy safer, experts say.

Centers for Disease Control and Prevention officials said the guidance is in keeping with growing evidence that people with the coronavirus are most infectious in the two days before and three days after symptoms develop. CDC Director Rochelle Walensky said the country is about to see a lot of omicron cases.
