If he is posting pics of his blister hoping for some compassion, he aint getting it there. He will probably be abused for complaining about "minor inconvenience" to protect everyone else. How dare he hope for a more painless booster? Does he think the whole Pfizer and Moderna revolve around his convenience. The will tell him what to shove and where to shove it, and he better do it, no questions asked, and better keep that smile on his face and dont forget to say "Thank you ma'am".
