Additional information: The Booster had much more severe side effects than the first two doses. My joints hurt so that I could walk barely and my armpits hurt very badly. I felt the same level of nausea, migraine, and chills. I'm glad I didn't know beforehand because I might have missed the booster. I understand these effects to be a strong immune response which is good news and I'm very grateful to Pfizer for providing these vaccines. I won't tell anyone how awful I feel because I would not deter anyone. At one point though the side effects were scary and I thought how awful for those suffering Covid in the hospitals and dying. I am trying to convince my son who is in a Frontline occupation to get the booster. Still, I thought you should know the side effects were pretty rough. Still, I'm very grateful. Took hydrocodone though I had been greatly reduced. Pain subsided after 2.5 days. Prior to the vaccination, the patient was not diagnosed with COVID-19. Since the vaccination, the patient had not been tested for COVID-19. Weakened immune system. Specific Relevant Test For Thromboembolic Events with Thrombocytopenia was unknown. Patient did not need emergency medical treatment due to the Booster. Children will be very wary if they have similar side effects. (Praying). No follow-up attempts are possible.
