The World Health Organization again requested Wednesday that people who have been vaccinated against COVID-19 not receive a booster dose so that vaccines can be sent to poor countries that have only been able to vaccinate a small part of their population.

"Currently we do not wish to see a generalized use of booster doses for people who have finished their vaccination in good health," WHO Director-General Tedros Adhanom Ghebreyesus told a press conference.

"I will not remain silent when companies and countries that control global supplies of vaccines think that the world's poor should be content with crumbs," he added angrily.

In early August, the director of the World Health Organization wanted to issue a decision to freeze the administration of booster doses until the end of September, but many rich countries publicly opposed it and launched their campaign to start giving the third dose of the vaccine.

However, Tedros called Wednesday for "the extension of the moratorium at least until the end of 2021 to allow each country to vaccinate at least 40% of its population."

Wednesday, Washington renewed its rejection of the World Health Organization's appeal, stressing, in the words of White House spokeswoman Jen Psaki, that President Joe Biden "has the responsibility to do everything in his power to protect people in the United States."

Psaki stressed that giving a booster dose in rich countries does not prevent her from donating vaccines to poor countries.

"We're doing both things together (giving a booster dose and donating vaccines to poor countries), and we believe we can do both things together and will continue to do both," she said.

The World Health Organization has consistently condemned the difficulties in accessing vaccines for poor countries.

He added, "The global goals of the World Health Organization remain to help each country vaccinate at least 10% of its population by the end of the month, at least 40% by the end of the year, and 70% of the world's population by the middle of next year."

He also indicated that he participated in the last meeting of the G20 health ministers on Sept. 5-6 in Rome: "They assured me that they would do their utmost to secure the necessary vaccines to reach the 40% target by the end of this year."

The head of the World Health Organization also said he was "stunned" by comments from the pharmaceutical industry that indicated Tuesday that production of vaccines against Covid will soon be more than enough to ensure a vaccination for everyone.

"In fact, manufacturers have always had the ability to not only vaccinate their priority populations but at the same time support the vaccination of the same collections in all countries," Tedros said.

"We have solutions to stop transmission (of the virus) and save lives. But these solutions are not well used and are not well shared," he said.
