From Science Daily:
“In a newly published study, physician-scientists at the University of Miami Miller School of Medicine have shown that the flu vaccine may provide vital protection against COVID-19.” The article speculates (intelligently) that the flu shot boosts your immune system which gives some protection against Covid-19.
I got my flu shot today (August 27) and encourage you to get yours unless your doctor has a reason you shouldn’t get it (e.g. reactions to the eggs in which the vaccine is produced). Nothing on this web site constitutes medical advice, which I am not qualified to give, so follow your doctor’s instructions.
