I get an annual flu shot because of the risk catagories I am in. I will get an annual SARS-covid2 shot for the same reason. I really do not see the need for healthy people to get an annual shot, at least at this time. Ron, I will try to say this politely and softly. With your heart, and your weight please ask a qualified doctor about this. This is just my opinion but I do not think your family doctor is the right person. This is a question I hope you will ask a virologist.
