GENEVA: World Health Organization (WHO) said the Current Covid-19 vaccinations, may need to be updated in order to give continuing protection against new variants, such as Omicron.
Although current vaccines provide a high level of protection against severe disease and death caused by Variants Of Concern (VOC), the WHO's Technical Advisory Group on Covid-19 Vaccine Composition (TAG-CO-VAC), a group of 18 experts, said on Tuesday that future vaccines that can prevent infection and transmission are needed.
Meanwhile, the composition of current Covid-19 vaccinations may need to be changed to fight against the virus's development. These revisions must be based on strains that are genetically and antigenically similar to the circulating variants. In order to "avoid the need for subsequent booster dosages," they should also elicit "wide, powerful, and long-lasting" reactions, according to WHO.
Experts have urged Covid-19 vaccine manufacturers to give data on the performance of current and Omicron-specific vaccinations in order to determine when vaccine composition adjustments may be necessary. Experts stressed the necessity of broader global availability to current Covid-19 vaccinations in relation to the current Omicron version.
