Turkey reported today that CoronaVac was 91.25% effective in phase 3 tests conducted in the country. The researchers also said that this rate may increase when advanced results are published. CoronaVac is the vaccine against covid-19 developed by the Chinese laboratory Sinovac and partners from other countries, such as Turkey and Brazil.
The Turkish government’s scientific council said no major symptoms were detected during vaccine trials in the country, except for one person who had an allergic reaction.
The purchase of 50 million doses of the immunizer from the Chinese laboratory Sinovac was agreed on December 11, but the shipment was postponed.
Turkish Health Minister Fahrettin Koca said that the vaccines will arrive in Turkey next Monday (28), adding that the country will vaccinate around 9 million people in the first group, starting with health professionals.
Postponed announcement
In Brazil, yesterday, the Butantan Institute and the São Paulo State Government did not report the effectiveness rate of the immunization test in the country, but announced that it was safe and effective enough to request the emergency use registration.
The official version of the São Paulo executive was that Sinovac will review the data before sending them to Anvisa (National Health Surveillance Agency). The agency should only receive the documentation within 15 days, when it will analyze the information and decide whether to approve the use of the immunizer in national territory.
Asked about Turkey’s results, the São Paulo institute said that it “does not comment on information about Sinovac’s contracts with other countries.”
“In clinical tests carried out in Brazil with 13 thousand volunteers, the vaccine has already proven to be extremely safe and with a level of effectiveness higher than that indicated by the WHO (World Health Organization)”, says the note. “This is a great step forward, because, based on the results obtained so far, mass vaccination using the immunizer would already guarantee significant reductions in the number of hospitalizations for complications related to the coronavirus.”
According to the team of Governor João Doria (PSDB), by the end of this month, Butantan will have 10.8 million doses of the Sinovac vaccine on Brazilian soil. Today a shipment with 5.5 million doses arrived at the Viracopos airport in Campinas (SP).
To be used in Brazil, any vaccine must have the registration approved by Anvisa.
