In the period 27 December 2020 to 15 February 2021, about 29,400 of Norway’s roughly 35,000 nursing home patients were vaccinated with the [Pfizer–BioNTech] mRNA vaccine BNT162b2. During the same period, the Norwegian Medicines Agency received 100 reports of suspected fatal adverse reactions to the vaccine. The mean age of the patients was 87.7 years (range 61–103 years). Among 100 reported deaths, a causal link to the vaccine was considered probable in 10 cases, possible in 26 and unlikely in 59. Five were unclassifiable.
