U.S.-based Novavax partnered with the Serum Institute of India to apply in the three countries, and plans later this month to also seek the World Health Organization review needed to be part of the COVAX global vaccine program.
The Biden administration has kept in place travel restrictions that have severely curtailed international trips to the U.S., citing the spread of the delta variant of the virus. Under the rules, non-U.S. residents who have been to China, the European Schengen area, the United Kingdom, Ireland, Brazil, South Africa and India in the prior 14 days are prohibited from entering the U.S.
The U.S. Centers for Disease Control last week warned the Delta variant of the virus is so contagious, vaccinated people who do get infected could be just as big a risk to others as people who aren't vaccinated.
The new requirement, which will be phased in over several weeks in August and September, is the most aggressive step the city has taken yet to curb a surge in cases caused by the delta variant.
The findings have the potential to upend past thinking about how the disease is spread. Previously, vaccinated people who got infected were thought to have low levels of virus and to be unlikely to pass it to others. But the new data shows that is not the case with the delta variant.
