South African variant can ‘break through’ Pfizer vaccine: Israeli study
JERUSALEM — The coronavirus variant discovered in South Africa can “break through” Pfizer/BioNTech’s COVID-19 vaccine to some extent, a real-world data study in Israel found, though its prevalence in the country is low and the research has not been peer reviewed.
It appears that the AstraZeneca jab has a much lower efficacy rate than either Moderna, Janssen or Pfizer. But guess which one Canada seems to have the most of for the GTA? Yup AstraZeneca.
Thank that schmuck in Ottawa for subjecting you to Vaccine Roulette. And given we now live in Bananada I wonder who is getting the highest efficacy vaccines if indeed their ratings are reliable?
Official: Chinese vaccines’ effectiveness low
The effectiveness of a Sinovac vaccine at preventing symptomatic infections was found to be as low as 50.4% by researchers in Brazil, near the 50% threshold at which health experts say a vaccine is useful. By comparison, the Pfizer-BioNTech vaccine has been found to be 97% effective.

The Pfizer and Moderna vaccines have the highest efficacy at around 95 per cent. Lower efficacy, in the 60 to 70 per cent range, was found for the AstraZeneca and Janssen products. (Efficacy measures how many vaccinated people contract COVID-19 compared with how many infections occur in the placebo or control group. Put another way, it represents the proportion of COVID-19 infections that could be prevented by vaccination).
