Geneva: The Technical Agency of the World Health Organization said on Tuesday that the Covid-19 vaccine is currently possible to reworked to ensure they are effective against omicrons and variants of Coronavirus in the future.
Technical groups, consisting of independent experts, said they would consider changing vaccination composition and emphasizing that shots need to be more effective in protecting infection.
“Covid-19 vaccine compositions currently may need to be updated to ensure that the Covid-19 vaccine continues to provide that recommends the level of protection against infection and disease by the VOC (a concerned variant), including the omicron and future variants,” the body is technical, assigned to Make recommendations to WHO, say in a statement.
“Covid-19 vaccines need to …
improve the vast, strong, and durable immune response to reduce the need for a consecutive dose of booster,” he added.
“Vaccination strategies based on repeated booster doses of the original vaccine composition cannot be appropriate or sustainable.” However, the statement stopped advocating Omicron’s special vaccine at this stage, said more research was needed and urged producers to share data.
It is said that the updated vaccine can be aimed specifically on the dominant variant, which is currently Omicron in many places, or becomes a “multivalent vaccine” designed to eliminate multiple variants at once.
Further recommendations will be issued when more data is available, he added.
Some vaccine makers have developed the next generation vaccine targeting Omicron, a very contagious variant first detected in South Africa and Hong Kong.
On Monday, Chief Executive Pfizer Albert Bourla said the redesigned Covid-19 vaccine that specifically targets the Omicron variant may be needed and the company can have one that is ready to be launched in March.
Inc.
rivals also do vaccine candidates who are adjusted to Omicron, but it is not possible to be available in the next two months.
An official who previously said the problem of vaccine composition needed “global coordination” and should not be handed over to producers to decide for themselves.
