U.K. Study Fails to Prove Masks Work in Schools

England introduced new mask rules in schools to curb the spread of Covid based on a study that didn’t provide conclusive evidence of their effectiveness, according to a report published by the Department of Education.

The government announced on Monday that secondary-school students in England have to wear face coverings from this term in an effort to stop the spread of the omicron variant. The other U.K. nations -- Wales, Scotland and Northern Ireland -- had already put in place such measures.
