Hours after the unanimous vote from its independent advisory committee, the Centers for Disease Control and Prevention has signed off on recommending booster shots for the Moderna and Johnson & Johnson COVID-19 vaccines for certain populations.

CDC Director Rochelle Walensky recommended boosters for Pfizer and Moderna recipients with no preference on the brand, leaving that decision up to the individual.

People who are 65 and older, or individuals as young as 18 who have underlying medical conditions or live in high-risk or long-term care settings, are eligible to receive either a Pfizer or Moderna booster at least six months after their second shot, the CDC said.

The one-shot Johnson & Johnson vaccine is eligible to anyone aged 18 and up, at least two months after their initial dose, the CDC said.

An independent Centers for Disease Control and Prevention advisory committee voted unanimously Thursday evening to recommend booster shots for both the Moderna and Johnson & Johnson COVID-19 vaccines for certain populations.

The panel recommended a third dose of the Moderna vaccine at least six months after a person’s initial course for those 65 and older, as well as those as young as 18 who are at higher risk due to underlying health conditions or where they work or live.

A second dose of the one-shot Johnson & Johnson vaccine was recommended for anyone aged 18 and older, at least two months after the first dose.

The panel also cleared the way for allowing mixing and matching of booster doses.

The recommendations fall in line with the Food and Drug Administration’s authorization of the boosters Wednesday.

CDC Director Rochelle Walensky must now sign off on the panel's recommendations. A decision is expected within a day.

COVID-19 hospital admissions in the U.S. have dropped by about 9.7% in the last week, according to federal data.

Death rates are also falling, though they remain persistently high, with an average of just under 1,250 Americans dying from the virus each day, according to the data.

Alaska currently has the country's highest infection rate, followed by Montana, Wyoming, Idaho and North Dakota.

The U.S. is currently averaging around 76,000 new cases per day, down from 160,000 in early September. Despite boasting high vaccination rates, several Northern states continue to see cases tick up as the weather gets colder.

The U.S. vaccination initiation average is at one of its lowest points since the introduction of vaccines nearly 10 months ago, according to federal data. Just over 182,000 Americans are receiving their first dose each day, while roughly 335,000 Americans are receiving a booster shot each day.

More than 112.5 million Americans remain unvaccinated and about 64.3 million of the unvaccinated are over the age of 12, and thus currently eligible for a shot, according to federal data. 

The FDA authorized boosters for Moderna and J&J late Wednesday. The Moderna booster is authorized for adults 65 and older and those at high-risk. The J&J booster is authorized for adults at least two months after their primary vaccination.

The FDA said it's OK to mix a booster but did not say any booster combination was preferred over another.
