WHO : Current Covid vaccine composition may need an update for Omicron

A technical advisory group established by the World Health Organization said on Tuesday that current Covid19 vaccines may need to be updated to ensure they are effective against new variants like Omicron.

The members of the group have advocated for “urgent and broad access” of the existing vaccinations internationally, both for protection and to prevent the introduction of new variants of concern or Variants Of Concern (VOCs).

As per the UN, the 18 experts are working on developing a framework to evaluate incoming VOC evidence “in the context of criteria that would trigger a recommendation to change Covid19 vaccine strain composition and will advise WHO on updated vaccine compositions, as required.” 

“Until such vaccines are available, and as the SARS-CoV-2 virus evolves, the composition of current Covid19 vaccines may need to be updated, to ensure that Covid19 vaccines continue to provide WHO-recommended levels of protection against infection and disease by VOCs, including Omicron and future variants,” they wrote.
