He considered that “this indicates that it may be more transmissible and that current vaccines may be less effective.”
Public health officials in Britain expressed serious concern about the mutation, which recently spread in South Africa, because it contains twice the number of mutations in the highly contagious “delta” strain, including mutations associated with avoiding an immune response.
The British Health Security Agency said that the strain, which was named “B1.1.529”, contains a so-called “spike protein” completely different from the protein found in Corona Virus The original, which vaccines are designed to resist.
The new strain carries mutations that are likely to evade the immune response resulting from both previous infection and vaccination, as well as mutations associated with increased infection.
Scientists said that laboratory studies are needed to assess the possibility that the mutations will result in a significant reduction in the effectiveness of Vaccines.
Earlier Thursday, scientists from South Africa They have discovered the new strain of corona in small numbers, and are working to understand its possible repercussions.
The scientists told a press conference that this strain contains a “very unusual set” of mutations, which are of concern because they may help the virus evade the body’s immune response and make it more transmissible.
The new mutant was also found in Botswana and Hong Kong.
The British Health Security Agency said that no cases of this strain were discovered in Britain, and that its scientists are in contact with their colleagues in South Africa to see their data.
