About half a dozen different international locations are contemplating the concept. If these international locations additionally start providing booster photographs, “this will require an additional 800 million doses of vaccine,” stated WHO chief scientist Soumya Swaminathan at a press briefing on Monday. 

Those doses ought to be going to international locations which have had little entry to the vaccines, stated WHO director-general Tedros Adhanom Ghebreyesus. He condemned wealthy and middle-income international locations for considering third doses when frontline employees and older adults in poor international locations haven’t but acquired their first dose. Some international locations have but to launch mass vaccination campaigns. “Currently, data shows us that vaccination offers long-lasting immunity against serious and deadly covid-19,” he stated. “The priority now must be to vaccinate those who have received no doses and protection.” 

Craig Spencer, director of worldwide well being in emergency drugs at NewYork-Presbyterian/Columbia University Medical Center, put it extra bluntly. “No matter what pharmaceutical companies tell you, you don’t need a Covid-19 booster more urgently than all the healthcare workers around the world who haven’t yet had access to a vaccine,” he tweeted. 

That’s to not say that we received’t want boosters ultimately. “It may well be that you need boosters after a year or two years,” WHO’s Swaminathan stated. Wherry notes that it’s good to be ready. But he has not seen any knowledge to persuade him that boosters are warranted now. “The emerging data says immunity is holding strong,” he says.
