On November 4th I'm scheduled to receive my second Covid-19 booster. This will be a total of 4 injections for me. The current boosters have been reformulated to include protection against one of the sub-variants of Omicron.
My first booster I felt tired and a bit feverish for only one day. My arm was tender for a couple days after. Exercise your arm by keeping it moving will help it feel better quicker. Also, I've never came down with COVID-19, yet anyway!
