It worries me that we may have to keep having vaccines going forward. I’m due my booster which I will take but I’m hearing that AZ are in the process of tweaking the current vaccine to combat the new strain. So we are then required to take another booster. Many variants can crop up, suppose another one does very soon. I’m concerned about the number of vaccines we could be taking. Is anyone else? And no I’m not an anti vaxer.
