Not just COVID vaccines but ALL vaccines. Flu, COVID, etc. You will have to get tested and if you are seen as not immune for something will have to get a new cycle. Also we are trying to be physicians. Vaccines are made through research, study, and trials. We should be for vaccines as physicians. Yes I understand people see the new COVID vaccine as a new type, but we should trust the science and the work/research put into it by those who came before us. Be skeptical, that is fine, that is science, but follow the studies and research presented by others who have been in the game longer than us. If you doubt the countless studies showing the safety and efficacy of vaccines, how will you trust future studies showing new methods of treatment for disease?
