The World Health Organization has said that the corona vaccines in the world need to be made more effective to provide continued protection against Omicron variants. The WHO’s Technical Advisory Group and a group of 18 experts on the composition of the corona vaccine said on Tuesday that although current vaccines provide a high level of protection against severe disease and deaths due to Variant of Concern (VOCs), the current vaccines are still at risk. In the future, however, we need to develop vaccines that can prevent infection.
In the meantime, there is a need to make vaccine vaccines against the corona virus more effective, so that the virus can be stopped from spreading, the organization said. There is a need for such compositions, which are genetically and antigenically close to the rapidly spreading variants, that reduce the need for frequent booster doses and provide broad, robust and long-lasting responses, the WHO said.
Omicron fast-forwarding its Delta variant
Experts encourage corona vaccine manufacturers to provide data on the performance of current and Omicron-specific vaccines to help decide when changes to vaccine composition may be needed. With regard to current Omicron variants, experts stressed the importance of widespread global access to current corona vaccines.
The WHO also said that the Omicron form of the corona virus is rapidly overtaking its delta variants and cases of infection from this form are now being reported all over the world. A senior WHO official has warned in this regard. A Global Health Agency official has warned that there is “increasing evidence” that Omicron can evade immunity but that the severity of the disease is lower than other forms.
Due to Omicron, people are getting admitted to the hospital
Maria Van Kerkhove, infectious disease epidemiologist and ‘Covid-19 technical lead’ at the WHO, said on Tuesday that it may take time for Omicron to dominate the delta in some countries, depending on the level of spread of the delta form in those countries. . Kerkhov said during the online Q&A session, “Omicron has been found in all the countries where the technology of genome sequencing is good and it is probably present in all the countries of the world.” It is rapidly overtaking Delta in terms of spread. And so Omicron is becoming the dominant form whose cases are coming to the fore.
He also cautioned that while there is some information on Omicron being less severe than the delta form, “it is not a mild disease” because “Omicron may also lead to hospitalization of people.” It’s coming.’ According to the Kovid-19 weekly epidemic update data released by the WHO, 15 million new cases of Kovid were reported worldwide in the week of January 3 to 9, which is 55 percent more than the week before that when about 95 lakh cases. had come. There were cases of death of about 43,000 patients last week. Till January 9, more than 30.40 crore cases of Kovid-19 had been reported and more than 54 lakh people had died of the infection.
