This might be stupid question but are there any pre and post pfizer vaccine tips ? some people say drink a lot of water and keep moving the arm?

This is actually a pretty good question. No need to prepare prior to vaccine, although good hydration is always advisable. After the vaccine, should you develop any soreness at the injection site, muscle aches, chills, etc, Tylenol as needed, can be taken every 6 hours. Symptoms should subside within a day or two.

Prior to the vaccine no prep is necessary…afterwards drink plenty of fluids, and if arm is sore can take ibuprofen every 6 hours or acetaminophen every 4 hours as needed. It’s great that you’re getting a Covid vaccine!!
