While the FDA voted to approve a booster for high-risk individuals and those over 65, the CDC’s expert advisory committee did not. The panel voted against recommending a booster for high-risk individuals based on their profession or living conditions, recommending only those over the age of 65 should be eligible for a booster at this time.
CDC director Rochelle Walensky overruled her own experts on September 24, 2021, recommended a booster dose for adults at high risk of infection due to profession or living conditions.
Walensky also stressed that boosters will also be authorized for Moderna and Janssen. As reported by CNN:
“Walensky said boosters for people who have gotten the Moderna and J&J vaccines will be addressed with similar urgency as Pfizer's vaccine. She reiterated that the current booster recommendations are only for people who received their second dose of the Pfizer/BioNTech Covid-19 vaccine more than six months ago.
‘We haven't forgotten you if you've gotten Moderna and J&J,’ Walensky said, when asked how soon boosters for these groups might be seen, and if mixing and matching of vaccines could happen in the near future. ‘We will with similar urgency address boosters for those populations, as well as looking at the science and data for mix and matching.’"
In Australia, despite the government already having secured an additional 85 millions doses of the Pfizer vaccine for 2022 and 2023, there is not much public discussion about for whom and when the boosters will begin rolling out.
