Boosted
I received my booster vaccination at lunchtime today (Wednesday, January 12). My first two doses of Covid-19 vaccine were the virus-mediated version from AstraZeneca, with the second of these having been stuck into my arm in early September 20211.
Today I was speared in the same arm with the Pfizer vaccine, which is a messenger RNA (mRNA) type. This time, I hardly felt the needle, presumably because it was finer than those used for my two AstraZeneca doses.
