● Crown disease 19 epidemic situation
WHO shows that the coronary vaccine is still effective in Omikon, especially for preventing severe illnesses and death.However, these vaccines may still need to be updated to continue to provide enough protection for people.The European Drug Administration also stated that repeated vaccination additions every four months may eventually weaken the immune system and make the vaccinator tired.

(Geneva Composite Electric) The World Health Organization experts pointed out on Tuesday that existing crown vaccines are still valid for Omiko strains, but they are constantly adding to vaccination, not long -term measures against new strains.They believe that the medical community may update the existing vaccine components for new strains and develop new vaccines that can better prevent infection and spread.
The European Pharmaceutical Administration (EMA) also said that the vaccine addition agent will be vaccinated every four months, which is not a sustainable long -term strategy. This may weaken the immune system.
The WHO Coronal Vaccine Component Technology Consulting Group (Tag-CO-VAC) issued a statement on Tuesday saying that the crown vaccine that has been urgently used by WHO is still effective for Omikdon, especially in particular, especiallyIt provides a high degree of protection for prevention and death.However, these vaccines may still need to be updated to continue to provide people with sufficient protection to cope with the current and possible new variant viruses.
The group experts are currently analyzing evidence related to the mutant strains that "need attention", and may modify suggestions for the component of the coronary vaccine.Specifically, the component of the updated vaccine strain needs to be similar to the mutant virus that is spread on genes and antigens.
The group pointed out: "In addition to preventing severe illnesses and deaths, it is also necessary to develop coronary vaccines that can effectively prevent infection and spread." Such a new vaccine will help reduce community transmission cases, and then reduce reductionImplementation of strict and extensive public health and social measures.
The statement says: "Repeated additional vaccination strategies for vaccination are unlikely to be appropriate or sustainable." Moreover, the crown vaccine must cause "extensive, strong and long -lasting immune response reactions", To reduce the demand for subsequent vaccinations.
So far, WHO has included eight crown vaccines on an emergency use list.At present, there are as many as 331 crown diseases around the world.
Some pharmaceutical factories have started to improve the coronary vaccine.Pfizer and partner Biontech plans to launch vaccines specifically targeted at Omikon in March, and are developing a multi -price crown vaccine that can also respond to Omikon and other strains at the same time.Modner is also developing an additional vaccine for Omikon, and is expected to be listed this fall.
At the same time, the European Drug Administration (EMA) also said that every four months, the vaccine addition agent is repeated, and this may eventually weaken the immune system and make the vaccination people feel tired.The agency recommends that countries should leave more time between the additional vaccination plans according to the blueprint of the flu vaccine strategy and linked the time of vaccination with the time of the cold season.
Cavali said on Tuesday: "Additional vaccination can be done or twice, but we should not think that it can be repeated ... we must think about it ...From the current popular environment, transition to the environment that is closer to local epidemic (Endemic). "
However, WHO pointedAnd predictable communication is premature time now.Simerwood, a senior emergency official of the WHO European Office, said: "The uncertainty is still very large, the virus has evolved quite fast, bringing new challenges. We can still be called a time point for local epidemic diseases in the future."
The Director of the WHO European Regional Office, Klutu, said that in the first week of 2022, more than 7 million crown disease confirmed cases were added. This number increased in two weeks.More than double.American Health Index and Evaluation Research Institute predict that according to this trend, in the next six weeks to eight weeks, more than half of Europe will have more than half of the population infection of Omikon.
