This would be a third shot of the current two-dose Pfizer and Moderna vaccines. That announcement could slide, the source cautioned, but this is the current timing.
“The FDA is closely monitoring data as it becomes available from studies administering an additional dose of the authorized COVID-19 vaccines to immunocompromised individuals,” an FDA spokesperson told CNN. “The agency, along with the CDC, is evaluating potential options on this issue, and will share information in the near future.”
Vaccine advisers for the US Centers for Disease Control and Prevention will meet on Friday to discuss booster doses of Covid-19 vaccines and additional doses for immunocompromised people, according to a meeting agenda posted by the agency on Monday.
A recent study by Johns Hopkins researchers found that vaccinated immunocompromised people are 485 times more likely to end up in the hospital or die from Covid-19 compared to the general population that is vaccinated.
It has been known for months that Covid-19 vaccines might not work well for this group. The hope was that vaccination rates overall would be so high so that the “herd” would protect them.
But it didn’t work out that way, because about a third of eligible people in the US have not received even one dose of a Covid-19 vaccine.
This is a breaking story and will be updated.
