Hello @smokie – good to see you once again. I had the Phizer vaccine, I had a mild reaction to the first dose, tired, headache for about a day, with the second dose, I had no reaction at all. I also had an antibody test, there was an excellent number visible. Of course, this does not mean I am safe from infection. I am comfortable the vaccine works, however I continue to be extra diligent when I am out and about in public.
