Had my 2nd shot of the Pfizer vaccine two weeks ago. Unlike the first shot which stung quite a bit, I barely felt the second shot at all. Waited to see if I was going to have any side effects as a few people I knew said that the 2nd shot was worse than the 1st. But as was the case with the 1st shot, I fortunately didn't really notice anything other than a bit of stiffness around the injection site that went away in less than 24 hours. If there were any actual side effects, I honestly couldn't tell. I continued wearing a mask for two weeks after the 2nd shot, but today was the first time in over a year that I went to work without a mask. I'll still continue to wear a mask when entering businesses that still require them, but even when I don't have one, I'll still practice some social distancing for the time being.
