Pfizer-BioNTech Vaccine Works Against UK, South Africa Variants

Pfizer and BioNTech, makers of a COVID-19 vaccine, said on Thursday that their product is effective against coronavirus variants that have emerged in the United Kingdom and South Africa.

In a statement, the two companies said the “small differences” detected in tests comparing the original virus and the recent versions “are unlikely to lead to a significant reduction in the effectiveness of the vaccine”.
