Covid vaccines from Pfizer/BioNTech and AstraZeneca are highly efficient against the Delta strain. This is mentioned in the research released in the New England Journal of Medicine magazine.

Two doses of Pfizer vaccine appeared to be 88 percent effective against the infection caused by the Delta strain. The full course of vaccination with the AstraZeneca drug showed 67-percent efficiency. Two doses of Pfizer and AstraZeneca are considered almost just as much effective against the Alpha strain. The difference in the efficiency levels was minimal.

According to the same research, one dose of Pfizer was effective against Delta by 36 percent, and one injection of AstraZeneca - by 30.
