Uncategorized Health Officials Advise That Residents Don’t Mix Vaccines While Adair County continues COVID vaccination efforts, health officials want to make sure residents are aware of an important part of the process. Jim LeBaron, Adair County Health Department administrator says the key to the distribution of more vaccine doses among more entities is understanding that for now, individuals should not mix vaccines. Both current two-dose vaccines, Pfizer-BioNTech and Moderna, are mRNA vaccines; however, there has not been sufficient research to determine how mixing them might inhibit the effectiveness of the vaccine. LeBaron says for now, if your first dose was the Pfizer vaccine, your second dose should be the Pfizer vaccine. If your first dose was the Moderna vaccine, your second dose should be the Moderna vaccine. LeBaron adds that while you need to stick with a single vaccine maker for both doses, you don’t have to stick with the same entity distributing the doses.
