FDA authorizes booster shots for Moderna, J&J vaccines
The FDA authorized booster shots for the Moderna and Johnson & Johnson vaccines for some populations Wednesday.
Moderna's vaccine can be administered at least six months after the second dose for people ages 65 and up and those ages 18 through 64 who either are at high risk of severe COVID-19 infection or have occupational exposure to the virus, the FDA said.
The J&J booster can be administered at least two months after the single-dose shot to those ages 18 and up, the agency said.
The FDA, which authorized Pfizer's booster dose last month, also said it will allow people to mix booster doses.

States can reserve vaccines for 5 to 11-year-olds beginning Wednesday
Beginning Wednesday, states can start reserving vaccines for kids ages 5 to 11, though vaccines won't start shipping yet.
The government has purchased enough shots for all 28 million children ages 5 to 11 in the U.S.
On Oct. 26, the FDA advisory committee is expected to have a public discussion and have a non-binding vote on the matter. Within days of that vote, the FDA is expected to authorize the vaccine for kids ages 5 to 11.
On Nov. 2 and Nov. 3, a CDC committee is expected to have a public discussion and non-binding vote.
The CDC director is likely to issue a formal recommendation within hours of the expected Nov. 3 vote. Administration of vaccine for 5- to 11-year-olds may begin as soon as the CDC director signs off.
