A second Covid-19 booster shot is available at many Missouri pharmacies. The Pfizer booster is approved for ages 12 and older while Moderna’s is available for those 18 years of age and older. Doctor Stephen Liang, a Washington University infectious disease physician in St. Louis, says he thinks there is enough booster shots to meet the demand.


Only individuals who have completed their primary vaccination series are eligible to get the booster. You can get the booster two months since your last primary or booster dose.
