GENEVA (AP) 鈥� The head of the World Health Organization called Wednesday for a moratorium on administering booster shots of COVID-19 vaccines as a way to help ensure that doses are available in countries where few people have received their first shots.
WHO Director-General Tedros Adhanom Ghebreyesus made the appeal mostly to wealthier countries that have far outpaced the developing world in numbers of vaccinations. He said richer countries have administered about 100 doses of coronavirus vaccines for every 100 people on average, while low-income countries 鈥� hampered by short supplies 鈥� have provided only about 1.5 doses per 100 people.
WHO officials say the science is unproven about whether giving booster shots to people who have already received two vaccine doses is effective in preventing the spread of the coronavirus.
The U.N. health agency has repeatedly called for rich countries to do more to help improve access to vaccines in the developing world. It has argued that no one is safe until everyone is safe because the longer and more widely the coronavirus circulates, the greater the chance that new variants could emerge 鈥� and prolong a global crisis in fighting the pandemic.
The agency has no power to require countries to act, and many in the past have ignored its appeals on issues like donating vaccines, limiting cross-border travel and taking steps to boost production of vaccines in developing countries.
Tedros pointed to a WHO target he had announced in May seeking to ensure that 10% of the populations in all countries receive vaccines against the coronavirus.
鈥淎ccordingly, WHO is calling for a moratorium on boosters until at least the end of September to enable at least 10% of the population of every country to be vaccinated,鈥� he told a news conference.
To help take the heat out of the pandemic, WHO has been focusing on getting vaccines to older adults, health care workers and other target populations in many countries before booster shot campaigns are carried out.
Dr. Bruce Aylward, a special adviser to Tedros, said the moratorium was about an appeal to countries considering booster doses to 鈥減ut a hold鈥� on such policies 鈥渦ntil and unless we get the rest of the world caught up" in the fight against the pandemic.
鈥滱s we鈥檝e seen from the emergence of variant after variant, we cannot get out of it unless the whole world gets out of it together. And with the huge disparity in vaccination coverage, we鈥檙e simply not going to be able to achieve that," Aylward said.
Israel, France, Germany and many Middle Eastern countries have already started administering boosters, and other nations, including the United States and Britain, are considering plans to do so in the wake of the emergence of the highly transmissible delta variant.
Dr. Katherine O鈥橞rien, WHO鈥檚 vaccines chief, noted that a 鈥渧ery limited number鈥� of countries were giving booster doses though a larger number were contemplating it.
鈥淭he evidence is evolving. It鈥檚 moving. We don鈥檛 have a full set of evidence around whether this is needed or not,鈥� O'Brien said, adding that the main message was that 鈥渨e need instead to focus on those people who are most vulnerable.鈥�
WHO officials reiterated their call for global 鈥渟olidarity鈥� to help battle the coronavirus pandemic and appealed to wealthy countries and corporations to help.
鈥淲e need everyone鈥檚 cooperation, especially the handful of countries and companies that control the global supply of vaccines,鈥� Tedros said, appealing in particular to the influential Group of 20 large economies. 鈥淭he G-20 has a vital leadership role to play as the countries that are the biggest producers, the biggest consumers and the biggest donors of COVID-19 vaccines.鈥�
He urged the G-20, which currently is chaired by Italy, to make 鈥渃oncrete commitments to support global vaccination targets.鈥�
鈥淲e call on everyone with influence -- Olympic athletes, investors, business leaders, faith leaders and every individual in their own family and community -- to support our call for a moratorium on booster shots until at least the end of September,鈥� Tedros said.
