US Drug Watchdog Imposes Heavy Restrictions on Johnson & Johnson Vaccine

Pfizer and BioNTech say their vaccine also works against the British and South African variants of the corona.


“Small differences” observed during research are unlikely to make the vaccine much less effective, the companies report in a joint statement.

The Pfizer / BioNTech vaccine has been used in the EU since last month. There is a significant concern there about the new corona variants, which are seen as more contagious.

Pfizer and BioNTech say the study shows no new vaccine is needed to fight new variants of the virus.

The companies emphasize that they continue to monitor how effective the corona vaccine is in practice. They say they will take action if necessary.
