FRANKFURT (Reuters) - The COVID-19 vaccine developed by Pfizer and BioNTech is likely to protect against a more infectious variant of the virus discovered in Britain which has spread around the world, according to results of further lab tests released on Wednesday.

The encouraging results from an analysis of blood of participants in trials are based on more extensive analysis than those released by the U.S. drugmaker last week.
