Britain has confirmed yet another spike in new COVID-19 infections, with close to 4,200 cases identified across the country Friday, the highest daily number in two months.
Seventy-five percent of the new cases in Britain are believed to be infections with the so-called Indian variant, first detected in India, which is more transmissible than the previously dominant variant.
Also Friday, Britain approved a single-shot COVID-19 vaccine developed by Johnson & Johnson. It is the fourth COVID-19 vaccine approved in the country, after inoculations made by Pfizer, AstraZeneca, and Moderna.
The European Commission has authorized the Pfizer-BioNTech COVID-19 vaccine for use in children as young as 12, widening the pool of those eligible to be inoculated, following similar approvals in the United States and Canada.
The commission made the announcement Friday after the European Union's medical regulator, the European Medicines Agency, Friday recommended the use of the vaccine in children ages 12 to 15, saying that data show it is safe and effective.
"Extending the protection of a safe and effective vaccine in this younger population is an important step forward in the fight against this pandemic," said Marco Cavaleri, the EMA's head of health threats and vaccines strategy.
