The U.S. Food and Drug Administration has approved boosters for the Moderna and Johnson & Johnson Covid-19 vaccines.
The Wicomico County Health Department began administering Moderna and J&J boosters on Monday. The Health Department will continue to provide initial doses of the vaccines and Pfizer boosters as well.
The FDA has also approved “mix and match” boosters.
A booster dose is an additional dose of a vaccine given after the protection provided by the original shot or shots has begun to decrease over time.
Typically, you would get a booster after the immunity for the initial dose naturally starts to wane. The booster is designed to help people maintain their level of immunity for longer.
The Moderna booster is given at least six months after the initial Moderna series.
Those eligible include people 65 years and older; people aged 18 to 64 years who are at high risk of severe Covid-19 illness; people aged 18-64 years with frequent institutional/occupational exposure to Covid-19.
The Johnson & Johnson booster is given at least two months after the initial J&J dose.
People 18 years and older are eligible.
Mix and match doses
The FDA has also approved “mix and match” Covid-19 boosters, meaning that a single dose of any of the available Covid-19 vaccines may be administered as a heterologous (“mix and match”) booster dose following the completion of primary vaccination with a different available Covid-19 vaccine.
The eligible populations and dosing interval for a “mix and match” booster dose are the same as those authorized for a booster dose of the vaccine used for the primary vaccination.
