US cases up nearly 40% since October

Puerto Rico, Florida and Hawaii have the nation's lowest infection rate, according to federal data.

One in every 427 Americans has died from COVID-19, according to data from Johns Hopkins University.

Fauci hopeful vaccine could be available for kids under 5 next year

Dr. Anthony Fauci says he's hopeful a COVID-19 vaccine could be available for children under 5 next year, but studies can't be rushed, making an exact timeline uncertain.

"Hopefully within a reasonably short period of time, likely the beginning of next year in 2022, in the first quarter of 2022, it will be available to them," Fauci told Insider, adding, "Can't guarantee it, you've got to do the clinical trial."

Pfizer's pediatric vaccine trials are already underway. The company estimates it could have early results for young children ages 2-4 by the end of the year, meaning authorization is possible sometime next year. Moderna is further behind, but also has ongoing trials in children as young as six months.

Clinical trials don't always unfold on a predictable timeline, and experts emphasize studies in young children won't be rushed.

FDA authorizes Moderna and Pfizer boosters for all adults

The FDA on Friday said it has authorized Pfizer and Moderna boosters for all adults, six months after the second shot.

“With boosters, more adults will now have the opportunity to help preserve a high-level of protection against this disease," Pfizer CEO Albert Bourla said in a statement.

“This emergency use authorization comes at a critical time as we enter the winter months and face increasing COVID-19 case counts and hospitalizations across the country,” Moderna CEO Stéphane Bancel said in a statement.

As for next steps, the CDC's independent advisory committee is meeting Friday afternoon to discuss boosters for all.

Austria to enter full lockdown, make vaccination mandatory

Austrian Chancellor Alexander Schallenberg announced Friday that the country will go into a full nationwide lockdown to curb a fourth wave of COVID-19 infections.

"We do not want a fifth wave," Schallenberg warned.

The lockdown will begin Monday and last for at least 10 days before the situation is reassessed. If the number of new COVID-19 cases has not dropped significantly, the lockdown can be extended to a maximum of 20 days.

Under the restrictions, people will be told to work from home, non-essential shops will close and public gatherings will be canceled. Schools will remain open for students who require in-person learning, but parents have been asked to keep their children at home if possible.

COVID-19 vaccination will also become mandatory by law in Austria, starting on Feb. 1.

It's the first country in Europe to make COVID-19 vaccines compulsory and the first to reimpose a full lockdown this winter, as the continent grapples with rising infections.

The Austrian government had initially imposed a nationwide lockdown only for the unvaccinated that began last Monday.


Long-term study of kids with COVID begins

The National Institutes of Health is starting a study to track the impact of COVID-19 infections in children, enrolling its first participant at the NIH's Clinical Center in Bethesda, Maryland.

The idea of “long COVID,” or long-term health impacts, is of concern in children, and is one of the reasons doctors strongly encourage pediatric vaccination. Six million children in the U.S. have had COVID-19, and many "experienced significant acute and long-term effects," the NIH said.

The study will track up to 1,000 children and young adults between 3 and 21 years old who previously tested positive for COVID-19 and evaluate the impact on their physical and mental health over three years.

The study will also try to determine risk factors for complications. It will evaluate the long-term immune responses to the disease, screen for genetic factors that may affect how children respond to COVID-19 infection and determine whether immunological factors influence long-term outcomes.
