Related:    Doctor describes how the flu shot could increase COVID risk. https://doctormurray.com/does-the-flu-shot-increase-covid-19-risk/ I stopped getting the flu shot a couple years ago because a) my research showed doubts it really worked and b) it made me feel awful for weeks after getting it and c) I've been able to beat the flu with home remedies (elderberry syrup especially).  I take elderberry syrup daily as a preventative.  I've not been nearly as sick as often the past couple of years as I used to when I got the flu shot.
