The risk of dying from Covid-19 is 20 times higher among people who are not vaccinated than those who had the double dose Pfizer vaccine, a new study by Discovery Health shows.
In the study, the Pfizer vaccine was found to be as effective at protecting people with two comorbidities, like diabetes, and equally beneficial to men and women.
Three months after the second dose — the vaccinations were being delivered during the third wave of infections driven by the contagious Delta variant — no waning in vaccine effectiveness was found. Wits University infectious diseases specialist Dr Jeremy Nel said: “The exact protection against death depends on the specific vaccine, the specific virus variant, and the time point at which it is measured, but on average, with Delta, people can probably expect to see 70% to 95% protection from hospitalisation, and about a 90% to 95% or higher reduction in the risk of death.”
“While immunity following an infection provides some protection from future Covid-19 complications, the risk of reinfection remains,” said Noach.
