Latest study shows two shots of Pfizer vaccine effective vs Delta - but getting second shot vital | Health24

Two doses of Pfizer's Covid vaccine are nearly as effective at preventing infection with the Delta variant as they are against the Alpha variant.

The researchers compared the effectiveness of the vaccine against the Delta variant with its effectiveness against the Alpha variant , which was the predominant virus variant between January and May 2021 in the UK – before the Delta variant took over, causing a surge in cases. The vaccine was found to be 48.7% effective after the first shot and 93.7% after the second shot.

They did, however, note that their study has several limitations, including that they are observational and should, therefore, be interpreted with caution.
