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.

A CDC committee is meeting Thursday to discuss and vote on booster shots for the Moderna and Johnson & Johnson vaccines, as well as if people can mix and match their booster doses.

On Wednesday evening, the FDA authorized Moderna and J&J boosters for some people and allowed for the mixing and matching booster doses.

The next step of the process is for the CDC panel to deliberate and ultimately vote on whether to recommend those boosters, and whether to allow mixing and matching. The CDC panel vote is expected around 4:30 p.m.

After the panel vote, CDC Director Rochelle Walensky will make the final decision, likely within one day. The panel's vote is nonbinding and the CDC is not required to follow the panel's recommendations.

Boosting for eligible Moderna and J&J recipients would be able to start once Walensky gives the greenlight.

The FDA has made it clear that there is no preferred booster vaccine for the mixed dosage, but the CDC panel on Thursday is likely to discuss available data on what booster blend might offer the strongest immunity.

Coronavirus infections are steadily falling across the country, thanks to significant declines in highly populated states such as Florida, Texas, Louisiana and Mississippi.

The number of daily cases in the U.S. has dropped 50% since Sept. 1, with a 43% drop in hospitalizations and a 21% drop in daily deaths.

However, an uptick in cases in Northern states is causing some concern.

In recent weeks, coronavirus infections have been creeping up in several states in the Upper Midwest and the Northeast. Eight states — Alaska, Colorado, Idaho, Michigan, Minnesota, New Hampshire, New Mexico, and Vermont — have seen notable jumps in their case averages.

Experts have been warning for weeks that Northern states could begin to see upticks in the coming weeks as winter approaches, and people start to head indoors.

Alaska currently has the country's highest case rate, followed by Montana, Wyoming, Idaho, West Virginia, and North Dakota, which all with case rates above 400 per 100,000 people.

Daily deaths are slowly falling, but remain persistently high. The nation is still reporting an average of 1,250 new deaths each day, and over the last four days alone, the U.S. reported just under 7,000 confirmed COVID-19 deaths.

The death average is still about 6.5 times higher than in mid-July, when the national average had dropped to a near pandemic low of 192 deaths reported each day.

Nationally, hospitalization numbers have dropped to under 60,000 patients with COVID-19 currently receiving care, down from 104,000 patients in late August. Hospital admissions have also fallen by about 10.4% in the last week.

Approximately 113.5 million Americans remain completely unvaccinated. Just under 65.2 million of those people are over the age of 12. The other 48 million unvaccinated people are children under the age of 12.
