WHO's Technical Body Says Updated COVID-19 Vaccines Needed To Combat Omicron: Reuters

A World Health Organization technical body said that current COVID-19 vaccines might need to be reworked to ensure they are effective against omicron and future variants of the coronavirus, reported Reuters.

• Some vaccine makers are already developing next-generation vaccines targeting omicron.

• The technical group said it would consider a change in vaccination composition and stressed that shots needed to be more effective in protecting against infection.
• "COVID-19 vaccines need to...elicit immune responses that are broad, strong, and long-lasting to reduce the need for successive booster doses," the technical body said in a statement.
• "A vaccination strategy based on repeated booster doses of the original vaccine composition is unlikely to be appropriate or sustainable."
• Moderna Inc MRNA is also working on a vaccine candidate tailored to omicron.

• However, the statement said that an updated vaccine could be aimed specifically at the dominant variant, which is currently omicron in many places or be a "multivalent vaccine" designed to combat several variants at once.
