The new booster from Pfizer-BioNtech and Moderna are bivalent vaccines, which means they target two strains -- in this case the original SARS-CoV-2 and the omicron BA.5 subvariant, which is currently causing the most cases. Pfizer's version is approved for ages 12 and up, while Moderna's shot has been approved for ages 18 and up.
You should wait at least two months from your last shot before getting a booster, according to the FDA.
On top of these state-specific options, pharmacies like CVS, Walgreens and Rite Aid have all begun offering booster shots at certain locations.

The New Hampshire Department of Health and Human Services has announced statewide availability of the boosters. Nearly 100,000 doses have been ordered and 56,000 have already arrived for distribution.
Those interested in getting a booster can contact their primary care doctor or visit www.vaccines.nh.gov for a full list of COVID-19 vaccination locations.
Rhode Island health officials said they are first prioritizing residents of long-term care facilities and assisted living facilities for the new booster, because these populations are at higher risk for serious complications from COVID-19.
The state is recommending the general public contact their primary care providers to see if they have boosters available. Independent pharmacies have also been scheduling appointments.
"This is a good reminder that one of the best ways to protect yourself and your family from COVID-19 is to stay up to date on vaccination," Gov. Dan McKee said in a media release. "The Rhode Island Department of Health continues to monitor vaccine availability closely and will ensure that this new, more comprehensive booster dose is available for Rhode Islanders as soon as possible."
