Covid-19 Booster Shots

October 21, 2021:
Covid Vaccine Booster Update

The following is an update on eligibility for Covid booster vaccinations through the Calvert County Health Department. Since the Delta variant entered Southern Maryland in late July, an average of 10-12 Calvert residents have been hospitalized at any given time as a result of Covid infections. We cannot emphasize strongly enough how important it is for every eligible person to get vaccinated against this disease. Due to the increasing number of breakthrough infections since the introduction of the Delta variant, those eligible for booster doses should consider taking advantage of additional protection for themselves and vulnerable people around them.

The FDA and CDC have authorized and provided guidance for people to receive a booster regardless of the brand of vaccine they initially received. They have also authorized people to receive a booster that is a different brand than their original vaccine, if they choose. Boosting a Johnson & Johnson vaccine with either Pfizer or Moderna likely improves immune protection to a greater extent than receiving an additional J&J dose. However, there is no current evidence that switching from Pfizer to Moderna or Moderna to Pfizer provides additional benefit.
