As CBS News correspondent Debora Patta reports, there are serious concerns among experts that new stocks could set back the fight against the pandemic.

South African officials have said that mutants that have more mutations than previously detected strains that have emerged worldwide have been a huge “virus” since the beginning of the global health crisis two years ago. It is said to indicate “evolutionary jump”.

According to public health expert Professor Salim Abdul Karim, the concern is that it may be more contagious or more resistant to current vaccine formulations.

“This variant Delta variant, It’s very difficult to predict, doing something different from what we’ve seen, that is, it will grow and spread around the world, “he told CBS News.

South African scientists are working 24 hours a day this week to determine how bad the new variant, previously called only B.1.1.529, is really. Lab results are still a few weeks away.

However, while the World Health Organization calls for a “risk-based scientific approach,” some countries still call for a travel ban not to be adopted, but some countries are detailed scientific. I decided not to wait for the analysis. The United Kingdom, France and Israel have canceled direct flights from South Africa and surrounding countries.

South African health officials said the reaction in other countries was premature, given little understanding of the new strain. Karim said it was detected only thanks to good scientific surveillance of COVID-19 cases in South Africa. It is especially looking for new variants. Few other countries have such a powerful genomic sequencing program to find strains.

“I’m sure other countries may not have the same level of diligence,” he told CBS News. “”

Since the first coronavirus vaccine became available over a year ago, WHO and public health experts around the world have been well vaccinated if doses are not shared with developing countries.

Pfizer partner BioNTech said Friday that it is already studying the effectiveness of both companies’ COVID vaccine formulations against the new strain.

A BioNTech spokeswoman told Agence France-Presse AFP, “We expect more data from clinical tests within two weeks at the latest.” “These data provide more information on whether B.1.1.529 may be an escape variant that may require vaccine adjustment if the variant spreads globally. Will provide. “
