Objective: To assess whether utilization of health care services for newly vaccinated health care workers changed after media attention about fatal side effects of the AstraZeneca vaccine on March 11th, 2021, and whether changes differed by age, sex, or occupation. Data sources: We utilized individual-level data on health care use, vaccination, employment, and demographics available in the Norwegian emergency preparedness register BeredtC19. Study design: Using an event-study design with a matched comparison group and multiple time periods, we compared the change in primary and inpatient specialist care use for vaccinated health care workers from 14 days before to 14 days after the information shock on March 11th, 2021. Data collection: Not applicable. Principal findings: Primary health care use rose sharply by 66% (95%CI 60.7 to 71.3) the week following March 11th for those vaccinated with AstraZeneca (n = 87,632), compared with no rise for the unvaccinated comparison group (n = 175,264). Utilization of inpatient care also rose by 20% (95%CI -3.7 to 43.7) in week one and 61% (95%CI 27.1 to 94.9) in week two after March 11th. The sharpest increase in primary health care use was found for women aged 18-44 (83%, 95%CI 76.6 to 89.5) and for cleaners working in the health care sector (103 %, 95%CI 36.1 to 166.9). Conclusions: Health care use was highly affected by the media reports of a few fatal or severe side effects of the AstraZeneca vaccine. Our results suggest that the reports did not only lead vaccinated individuals to contact primary health care more, but also that physicians referred and treated more cases to specialist care because of the new information.
