Second jab of AstraZeneca vaccine, in the same grocery store pharmacy as the first immunization 12 weeks ago. In the 15-minute observation period, I could feel my pulse rising, and slight headache starting. Appointment was punctual, with no other patients before or after me. Taking 2 days off work, in case of side effects. (Loblaws Pharmacy at Jeff's No Frills, Carlaw Avenue, Riverdale, Toronto, Ontario) 20210609
