The Pfizer or AstraZeneca vaccines for COVID-19 are nearly as effective against the Delta variant as they are against the previously dominant Alpha variant, when the person receives two doses of the vaccine, a new study published on Wednesday suggests.

The highly contagious Delta variant, first identified in India in late 2020, is now the dominant variant of the CCP (Chinese Communist Party) virus worldwide. The CCP virus causes the disease COVID-19.
