Geneva/Copenhagen: The World Health Organization (WHO) has said that existing COVID-19 vaccines may need to be updated if they are to provide continued protection against emerging variants, including Omicron.
The WHO’s Technical Advisory Group on the Covid-19 Vaccine Composition (TAG-CO-VAC), a group of 18 experts, said on Tuesday that although current vaccines provide a high degree of protection against serious illness and death due to the variants of concern, We do. VOC), future vaccines that can prevent infection and transmission, need to be developed.
Meanwhile, the creation of Current Covid-19 Vaccines Xinhua news agency reported that the update may need to be done to protect against the development of the virus.
Such updates need to be based on strains that are genetically and antigenically close to circulating variants. They should also achieve “broader, stronger and longer-lasting” responses, the WHO said, “to reduce the need for frequent booster doses.”
Experts encourage COVID-19 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 the current Omron version, experts stressed the importance of widespread global access to current COVID-19 vaccines.
Omicron wave will not be vaccinated in Europe: WHO
WHO’s European regional director, Hans Kluge, warns that the Omicron variant may become more prevalent Europe as “tidal wave” of infections spreads to the east.
Kluge said on Tuesday, “I am also deeply concerned that as the version moves east, we are not yet seeing the full impact of it in countries where vaccination levels are low. We are unaffiliated.” Will see more serious illness.”
According to him, omicron version, which is now spreading in the Balkans, is already present in 50 of the 53 countries in the region spread across Europe and Central Asia. “At this rate, the Institute for Health Metrics and Evaluation (IHME) estimates that more than 50 percent of the region’s population will be infected with Omicron in the next 6 to 8 weeks,” he said.
Kluge said that the transmission in the region is causing hospitalizations on an unprecedented scale.
To better manage the devastating impact of the coronavirus on health services, economies and societies, the WHO official called for immediate action and practical actions, including planning for contingencies, and prioritizing response systems during the “end window of opportunity”. Did.
He also stressed the importance of protecting vulnerable people and “minimizing disruption to health systems and essential services”. The WHO official also urged schools to remain open. “Keeping schools open has great benefits for children’s mental, social and educational well-being. School buildings should be the last to close and the first to reopen,” Kluge said.
Additionally, he outlined his five pandemic stabilizing mantras: vaccination, third dose or booster, increased use of masks, ventilation of crowded or enclosed spaces and new strategies to guide Delta or Omicron’s response. Continued use of clinical protocols.
And WHO Europe also said it was “far from” treating Covid-19 as endemic.
“We are still a way away. Endemicity, first of all, assumes a stable circulation of the virus at predictable levels and potentially known and predictable waves of pandemic transmission,” said Catherine Smallwood, senior emergency services officer for WHO Europe. Spain’s recent request to the European Union to discuss an opinion that COVID-19 can be classified as an endemic disease, similar to flu or malaria, always occurs in a particular population or region. exists.
“What we see in 2022 is nowhere near what we are seeing… we still have a virus that is evolving very rapidly and presenting a lot of new challenges… and still many more.” There’s all the unpredictability,” she added.
