Just read of BBC news about the booster shots for all over 50s and CEV rolled out from next week either Pfizer and Moderna being used. DM had AZ vaccines back in March/April. People who had AZ are they having Pfizer/Moderna? I can’t see any mention of AZ boosters. DM had awful reaction to AZ (yellow carded and GP involved) don’t think she’ll want to change to a different type of vaccine. Where can I find information on mixing vaccines for booster shot? And having 3 vaccinations? To me it seems the government are “putting all their eggs in the vaccine basket” when it has been proven you can catch and pass-on even with the vaccine.
