Not all anecdotes are equal. If a significant number of the TTLG family had come down with adverse reactions, and we all bore witness to it, that would be a credible anecdote. As it was, while most of us received regular vaccines, nobody here has reported side-effects in all that time. Compared to "a bunch of my friends and neighbours told me", out story fits the actual data.
COVID vaccines are four or five or six orders of magnitude more helpful than harmful.
