The executive director of the World Health Organization (WHO), Michael Ryan, said at a news conference on Friday, 23, that the purchase of vaccines is a matter of countries “national sovereignty” and that he believes “that the federal government will work what is best for Brazil “, in response to Jair Bolsonaro’s announcement not to purchase Chinese immunizers. Still on the Brazilian situation, Ryan stated that each country has a unique condition, having to observe the trajectory of the virus, but that there is currently a “very strong scientific infrastructure”, and that “conditions are now better” than at the beginning of the pandemic.
Regarding the release of remdesivir, announced on Thursday, 22, by the Food and Drug Administration (FDA), the US food and drug regulatory agency, Ryan said that institutions can release drugs that will not necessarily be used in therapies, with no conflict. . WHO chief scientist Soumya Swaminathan indicated that the data on which the FDA relied did not take into account the result of the Solidarity survey, which had not registered a drop in mortality from the prescription of remdesivir.
Swaminathan said that WHO should start making data on vaccine efficacy available in November, and that in early 2021, the institution should take a stand on recommending specific immunizers. This step should be followed by the application of vaccines to people at risk, which the scientist hopes will be well distributed globally. Defending the Covax initiative, he stated that it is the best option for countries to guarantee the vaccine, even citing Brazil. “We have to balance expectations,” he said, noting that only between 10 and 20% of vaccines are usually effective, but that there are, “fortunately”, many candidates for covid.
“Some countries have seen an exponential increase in cases and the situation is critical, especially in the Northern Hemisphere,” said WHO Director-General Tedros Adhanom. The director urged governments to do their utmost to “prevent the collapse of health services and for schools to close again”, in addition to “helping families and businesses to maintain themselves”. Some poorer countries have had many problems with oxygen supply, he said, citing some African nations in particular. On the subject, he said: “We support collaboration between countries and the private sector to provide oxygen”.
