(CBS DETROIT) – Pfizer and AstraZeneca's COVID-19 vaccines were found to be highly effective against new coronavirus variants.

This includes variants found in India and England.

Pfizer's vaccine was at least 88 percent effective in preventing symptomatic COVID-19 cases.

AstraZeneca's shots were 60 percent effective against the variant found in India.

Data shows getting both shots was vital because effectiveness was 50 percent or less after just one dose.
