China News Service, September 11, according to foreign media reports on the 11th, Kruger, the director of the European Region of the World Health Organization, said that the emergence of the mutant virus has "shattered" hopes for herd immunity and its ability to put a vaccine to end this new crown epidemic , Expresses pessimism
Foreign media Kruger told reporters on September 10 that the new crown virus may exist for many years, and health officials must now "predict how to gradually adjust our vaccination strategy", especially with regard to the issue of additional doses
Official In May 2021, Kruger said, "Once we reach at least 70% of the vaccination rate, the epidemic will end
Regarding whether the WHO is still targeting this number or must reach a higher target, Kruger acknowledged that the situation has changed due to the emergence of more infectious variants such as Delta
He said: "I think this makes us realize that the primary purpose of vaccination is to prevent severe illness, that is, to reduce mortality
He added: “If we believe that the new coronavirus will continue to mutate and be with us, just like the flu, then we should expect how to gradually adjust the vaccination strategy to adapt to local transmission, and collect information about supplemental vaccination.
Epidemiologists now believe that although vaccines are still essential to contain the pandemic, it is unrealistic to rely on vaccines to achieve herd immunity
Kruger said that high vaccination rates are also necessary to "relieve the pressure on the medical system," and medical institutions urgently need to deal with the treatment of other diseases that have been delayed due to the new crown epidemic
The report pointed out that Delta's transmission power is 60% stronger than the other variant Alpha, and twice as much as the original virus
