On an unspecified date in Feb2021, the patient experienced drop in body temperature and drop in blood pressure and he still feels chilling in his body. It was reported that the patient had the first vaccine 07Jan2021, Lot EL1284, and he and his wife didn't feel anything. Second dose of Covid vaccine 28Jan2021 EL1283, both in left arm. He does not see NDC or expiration on either vaccine card. Around the 5th day he started to have a drop in body temperature and also his blood pressure dropped. Has been visiting his doctor about that. Would like to know if that is a normal reaction. For the event Body temp dropped: He can't tell exactly what date but states it was 5 days after the 2nd dose, maybe four because he remembers he got the vaccine on Thursday and on Sunday he felt like he had to call his doctor at home to inform him. Or maybe it was on Monday and then he went to the doctor's office the following day. He still feels chilling in his body, but it is less and less but still feels it sometimes, he states it is improved but not completely normal yet. The drop in his blood pressure began the same day as body temperature drop. It is not ongoing; his blood pressure is back to his baseline. He has had high blood pressure in the past, so it is back to normal. He felt that he was freezing so he went to the doctor. Every day was less and less and less. There were no relevant tests done. Laboratory tests on an unspecified date included blood pressure measurement: back to his baseline, blood pressure measurement: drop on Feb2021 and body temperature: drop on Feb2021. The patient confirmed that these were the only two doses he has received of this product. His wife had some of the reactions at the same time, we were vaccinated at the same time and everything, same lot and everything. He said she did not have a drop in blood pressure, only the temperature. She also had a headache and stomach pain. The clinical outcome of drop in blood pressure was recovered and other events was recovering.  No follow-up attempts are possible. No further information is expected.
