A lot of people seem to be under the illusion that once you’ve had a Covid vaccine you are done and protected.  The signs show otherwise – you need to get repeat vaccines and those booster shots typically give you 4 to 5 months of very good protection and after that it starts to wane.  We are sure that pharmaceutical companies will come up with better vaccines that last longer as time goes by, but until they do I am going to continue to get my booster shots and additional vaccines when they are available to me.  I feel one has to take care with one’s health and part of that is reducing one’s reaction to a dangerous disease by making sure, if one is exposed to it, that one’s body has the right amount of immunity added to it by the booster shots.  I am getting the Pfizer booster shot, but if I had the choice I would get Moderna this time, because I very much like the whole mix and match principle and having the benefit of the different companies’ approach to vaccines.
