The New Normal: When could people receive the Moderna and Johnson & Johnson COVID-19 boosters?

News 12's Elizabeth Hashagen was joined by Dr. Daniel Griffin to discuss the death of Colin Powell and COVID-19 boosters.
Former U.S. Secretary of State Powell died from complications from COVID-19 at the age of 84.
According to CDC, among the 187 million vaccinated Americans there have been roughly 7,000 breakthrough deaths, with more than 6,000 over the age of 65, as compared to more than 700,000 COVID deaths among the unvaccinated. So breakthrough deaths can occur, but are rare.
This is what Dr. Griffin had to say about breakthrough deaths:
It's expected to be a big week for COVID-19 boosters. Millions of people who got the Moderna and Johnson & Johnson vaccine could be eligible for a booster by the end of the week.
A Food and Drug Administration panel unanimously recommended a Johnson & Johnson booster vaccine on Friday. The terms of the endorsement essentially call for the Johnson & Johnson COVID-19 vaccine to be a two-dose shot, rather than the one-dose shot for which it's been known since it first got emergency use authorization last spring.
The panel called for a second shot to be available to people 18 and older, at least two months after the first shot.
New data from the American Academy of Pediatrics showed September was the worst month for child COVID-19 infections. Could we see any movement on child vaccinations?
A new Nature article explains "hybrid immunity" (infection then vaccination) and why it essentially provides amazing protection. Here's what Dr. Griffin says about hybrid immunity:
