Vaccines are effective against variants
Islam News – Researchers have been tracking how well vaccines protect against the Delta variant of the coronavirus as it spreads. All the studies so far agree that most Covid-19 vaccines are very effective at keeping people out of the hospital and have generally protected against the Delta variant.
Though the numbers vary from country to country, experts say that’s to be expected, because it’s hard for a single study to accurately pinpoint the effectiveness of a vaccine in real world conditions.
Quotable: “Their overall implications are consistent: that protection against severe disease remains very high,” said one professor at the Johns Hopkins Bloomberg School of Public Health.
The numbers: In Britain, two doses of the Pfizer shot had an effectiveness of 88 percent protecting against symptomatic disease from Delta. A June study from Scotland concluded that the vaccine was 79 percent effective against the variant. On Saturday, a team of researchers in Canada pegged its effectiveness at 87 percent.
