The World Health Organization has called on pharmaceutical companies to update their Corona vaccines to provide stronger immune responses after warning that repeated booster doses are not sustainable, as the World Health Organization is pushing vaccine developers to work towards creating long-lasting Corona vaccines that are effective against future strains, as the organization believes. The continuous distribution of booster doses every year is not sustainable, according to the British newspaper, “Daily Mail”.

Albert Burla, CEO of Pfizer, said: PfizerThe virus will be around for the next 10 years, but it can be controlled by annual boosters. The World Health Organization has long criticized the launch of booster vaccines in the developed world, and instead developed countries wanted to donate doses abroad.

The World Health Organization is calling on vaccine manufacturers to prove future coronavirus vaccines rather than focus on rolling out regular boosters.

The WHO technical advisory group on developing a vaccine has issued Corona Crown COVID-19 TAG-CO-VAC A report this week says that planning to roll out booster doses regularly is not sustainable.

According to the British newspaper, “Daily Mail”, Pfizer Inc Pfizer The leading manufacturer of vaccines in the United States and many countries around the world, the company has made millions of dollars in vaccine contracts since the vaccines first became available in December 2020.

The newspaper said, the continued use of booster doses to control Corona may be necessary, and will certainly lead to significant financial gains for the New York-based company.

With the near-to-medium supply of available vaccines, the need for equal access to vaccines across countries to achieve global public health goals, and other considerations including vaccine demand, virus evolution, and a vaccination strategy based on repeated boosters, the WHO Technical Advisory Group on Vaccine Development wrote Corona TAG-CO-VAC The doses of the original vaccine formulation are unlikely to be appropriate or sustainable.

Health officials have deemed the current crop of vaccines safe and effective, but the protection provided by the doses wanes over time, even before the omicron variant appeared. Omicron Vaccine dodger health officials in the United States and several European countries have been rolling out booster doses to fill gaps in vaccine protection that diminish over time.

In the United States, a booster dose is recommended for anyone 6 months after receiving the Pfizer vaccine Pfizer , or 5 months from Moderna Modern, or two months after receiving the Johnson vaccine.

The World Health Organization working group says that future vaccines should be “based on genetically and antigenically close strains of the circulating corona variants, in addition to protecting against severe disease and death, but more effective in protecting against infection and thus reducing transmission in the community and the need for health and social measures.” rigorous and extensive, and “elicit broad, robust, and long-lasting immune responses to reduce the need for successive booster doses.”

The newspaper confirmed, led to the emergence of a mutant omicron Omicron The variant, first discovered by South African health officials in November, is the most mutated strain to date, and more than 30 mutations on the spike protein allow it to evade antibodies to vaccines that protect against infection, which are also The most contagious strain of the virus by far, causing cases in the US to reach record levels, As of Wednesday, the average number of new cases in the US is 786,000 per day, the most since the virus first arrived in March 2020.

Pfizer plans to Pfizer and her partner BioNTech Also to roll out a specially designed booster for the omicron . mutant Omicron In late March.

Borla said, earlier this week, that regular use of booster doses will be key to controlling the epidemic in the future.

وةضاف لشبكة CNBC “We will live a completely normal life, with only injections maybe once a year, noting that these regular doses may be necessary for up to ten years.

The World Health Organization has long criticized the distribution of boosters in high-income countries such as the United States and the United Kingdom, while other countries struggle to immunize their populations.

While the United States sits on a stockpile of unused vaccines, for example, only about 15% of the population of the African continent has received at least one dose of vaccines, the organization said.

In August, before the discovery of Omicron Omicron The Director-General of the World Health Organization, Tedros Adhanom Ghebreyesus, called for a halt to the booster doses for two months, in the hope that he would donate them to countries with poor vaccine supplies.

Tedros said, last August, that the unfairness of vaccines and the nationalism of the vaccine increases the risk of the emergence of more infectious variants, adding that he expected the emergence of a variant such as Omicorn. Omicron In the end.

The virus will have a chance to spread in countries with low vaccination coverage, the delta variant can evolve to become more virulent, and at the same time more virulent variants can also emerge.

The newspaper said, not only do many of these countries have the same access to vaccines as the developed world, nor do they have the resources to conduct strong vaccination campaigns, for this reason, the “Taj” group pushed TAG-CO-VAC company Pfizer And other manufacturers to use the current knowledge about Omicron And other strains of the virus to develop vaccines that last longer, and have properties that make them resistant to future variants.
