The World Well being Group warned Wednesday that new coronavirus variants might emerge throughout the pandemic that render the present vaccines ineffective.

“As this pandemic drags on, it is potential that new variants might evade our countermeasures and turn out to be totally proof against present vaccines or previous an infection, necessitating vaccine diversifications,” WHO Director-Basic Tedros Adhanom Ghebreyesus mentioned at a press convention in Geneva.

Tedros sounded that alarm as Covid instances hit record highs in many countries, together with within the U.S. The newest surge, coming greater than 21 months after WHO first declared Covid a pandemic, is fueled by the unfold of the brand new and extremely transmissible omicron variant.

Tedros reiterated his frequent requires nations to work collectively to enhance world provides and entry to Covid vaccines and different essential well being tools.

He additionally slammed the “populism” and “short-term nationalism” of some political leaders that he mentioned has “undermined fairness and created the perfect circumstances for the emergence of latest variants.”

“Misinformation and disinformation, typically unfold by a small variety of individuals, have been a relentless distraction undermining science and belief in lifesaving well being instruments,” the world well being chief mentioned.

He famous that “within the enormous waves of instances at present seen in Europe and in lots of international locations around the globe, misinformation which has pushed vaccine hesitancy is now translating to the unvaccinated disproportionately dying.”

Covid vaccines reminiscent of Pfizer and BioNTech’s photographs are nonetheless efficient at stopping extreme illness from omicron, consultants say, however they’re much much less efficient at stopping an infection from omicron. Booster photographs, however, considerably enhance safety from symptomatic illness attributable to omicron.

If a vaccine-resistant pressure of the virus emerges, producers must tweak their photographs, which “would probably imply a brand new provide scarcity,” Tedros warned Wednesday.

It is crucial for nations to construct up their native manufacturing provide of vaccines earlier than that occurs, he mentioned.

“This virus will proceed to evolve and threaten our well being system if we do not enhance the collective response,” Tedros mentioned. “I am extremely involved that omicron, being extra transmissible, circulating similtaneously delta, is resulting in a tsunami of instances.”

Vaccine provides are at present bettering, he mentioned, whereas repeating his criticism that wealthy international locations’ booster-shot applications are making it more durable for poor nations to acquire any vaccines. That rising inequity might lengthen the pandemic.

Regardless of the continuing public-health risk and the opportunity of future challenges, Tedros mentioned he’s “optimistic” the acute stage of the pandemic can finish in 2022.
