WHO: There is no evidence that the mutated new coronavirus in mink will affect the vaccine effect
Geneva, November 6 (Reporter Liu Qu) World Health Organization experts said on the 6th,There is currently no evidence that the latest mutation of the new coronavirus infecting farmed mink in Denmark will affect the effectiveness of the new crown vaccine in the future.
The Danish government recently announced thatIn view of the fact that there have been many cases of mink transmitting the mutated new coronavirus to people in the country,The government decided to culminate all domestic mink farms,In addition, stricter epidemic prevention measures have been implemented in 7 cities with more mink farms.Danish Minister of Health Magnus Hojnik said at a press conference on the evening of the 5th,The mutation of the virus may have an impact on the effect of the new coronavirus vaccine under development.
Sumia Swaminathan, the chief scientist of the WHO, said at a press conference on the 6th,How this mutation affects the spread of the new coronavirus, the severity of clinical symptoms, and the immune response,And it is too early to draw conclusions on the effectiveness of the potential new crown vaccine.
Maria Van Kelkhov, the technical leader of the WHO health emergency project, also believes thatThe mutation of the new coronavirus gene is normal,The organization has been tracking the virus mutation since the beginning of the new crown pandemic.Certain mutations in the virus may have some effects,However, WHO still needs further research and evaluation,Related work is currently in progress.
According to Michael Ryan, Executive Director of the WHO Emergency Project,To determine that the new coronavirus is in the mink group,And the spread between mink and people,Need more time.The existing evidence does not show how this mutant new coronavirus spread by mink is different from the past in its behavior.”The characteristics of the virus may be slightly different,But it is still the same virus.”He said,WHO is currently cooperating with relevant parties,In order to complete the first risk assessment of the Danish new crown virus “mink transmission” incident.
Although Denmark has culled farmed mink due to the spread of the new crown virus in farmed mink,Peter Ambarek, a virus expert from the Department of Food Safety and Zoonoses of WHO, still emphasized at the press conference,The risk of other farmed animals being infected with the new coronavirus is much smaller than that of mink.There are two reasons: first,research shows,Farmed animals such as pigs, chickens, and cattle are not as susceptible to the new coronavirus as minks.Even if infected,The virus cannot be maintained and spread like in the mink herd; secondly,The current modern farming system for producing pork and chicken allows us to completely isolate the virus and protect the environment from pollution.This means that it is easier to prevent and control the new coronavirus from entering the breeding environment.
