On Friday, the World Health Organization issued statements regarding the updates on COVID-19 vaccines.

The World Health Organization (WHO), alongside the Technical Advisory Group on COVID-19 Vaccine Composition (TAG-CO-VAC) and supported by its Strategic Advisory Group of Experts (SAGE) on Immunization, issued statements on Friday with the latest update on the COVID-19 vaccines.

WHO: COVID-19 Deaths Rise After Five-Week Decline

The TAG-CO-VAC is a group of experts in charge of periodically analyzing the emerging variants of the COVID-19 and the implications they could bring to the effectiveness of the vaccines. The same released a statement detailing the current updated COVID-19 vaccines.

Intended to extend the information offered by the TAG-CO-VAC statement, the WHO, along with SAGE on Immunization illustrate the decision-making considerations at the time of using the variant updated COVID-19 vaccines. WHO COVID-19 Vaccines Working Group was part of the team preparing the statement.

The statements explained that the new modified COVID-19 vaccines, based on the ancestral strain (or index virus) of SARS-CoV-2, have indicated a good response and strong protection against severe disease and death across all virus variants seen to date. For several countries, the main priority remains to achieve high coverage rates with the primary series and booster doses in the highest and high priority-use groups.

The statements remarked on the possibilities of the emergence of new variants, as the virus could continue to evolve. According to TAG-CO-VAC, should Omicron be included in a modified vaccine composition and administered as a booster dose, it will lead to immunity while retaining protection against severe disease and death.
