Data from Ontario: Even one COVID-19 vaccine dose provides strong protection against variants

by 22q Administrator

Scientists in Ontario have found that Pfizer-BioNTech, Moderna, and Astra-Zeneca vaccines are doing better than first expected.

Even a single dose of any of these three vaccines provide good to excellent protection against:

  • symptomatic infection
  • severe outcomes (hospitalization or death)
caused by the four variants of concern.

The scientists expect that two doses are likely to provide even higher protection.

Here is the news report from CP24 News:
