• A pre-print article from the UK reports on effectiveness of two doses of the Pfizer/BioNTech coronavirus vaccine and one dose of the AstraZeneca/Oxford coronavirus for preventing symptomatic COVID-19  in older people. Overall, the researchers reported that one dose of either vaccine is approximately 80% effective at preventing hospitalization for COVID-19 among older adults, and one dose of the Pfizer/BioNTech vaccine is 85% effective at preventing death from COVID-19.

In people age 80 years and above, the Pfizer/BioNTech vaccine was 70 percent effective at 10-13 days post- vaccination: by 14 days after the second dose, it was 89 percent effective. In people age 70 years and up, the Pfizer/BioNTech vaccine was 61 percent effective at 28-34 days post-vaccination, while the AstraZeneca/Oxford vaccine was 60 percent effective at 14-20 days post-vaccination, increasing to 73 percent at 35 days after vaccination. A single dose of both vaccines reduced the risk for hospitalization (the Pfizer/BioNTech vaccine, by 43 percent; the AstraZeneca/Oxford vaccine reduced this risk by 37 percent). Source
