What records are kept of severe reactions to these vaccines that don’t result in death. A fellow in the pharmacy last week mentioned his experience with AZ. Fit 65 year old had a bad reaction to first dose and couldn’t get out of bed for a week. When it came time for the second dose they said he would be fine. Four days after the jab he suffered a major stroke and hospital said he was lucky to be alive. It made us glad we decided to go for Pfizer.
