Release 1

Systemic reaction (other): 3 to 4 days after injection having headaches and high blood pressure . My Blood pressure medication stop working and BP went up to 161/105. Went to Emergency on 12/24/20. They gave me a second blood pressure medication and didn't start to work until 3 days later. They don't know why a spike in blood pressure MD said maybe my body is fighting virus. I think it's from the vaccination.

Release 6

Symptoms: Recently diagnosed with hypothyroidism

Release 10

Symptoms: After 1st vax, was in ER for high BP. Also developed hypothyroidism. After vax, now it's low and have to take meds. After booster shot, had high blood pressure problems and elevated D Dimer test for blood clot. I have developed so much health problem cut off by CDC

Free-text releases are not linked to a specific survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
