Brazil defends decision to reject Russian Covid-19 vaccine, citing safety and efficacy



SÃO PAULO – Brazil’s health authority says it has serious doubts about the safety and efficacy of Russia’s Sputnik V Covid-19 vaccine and defended its decision to block the emergency shot, saying Russia had no experience with vaccines and defended its responses. to the agency.

The agency, Anvisa, refused to approve the vaccine last week despite a shortage of Covid-19 shots in the severely affected country and the introduction of Sputnik V in more than 60 countries that have already approved the vaccine for use.

Brazil is concerned that the vaccine may contain active adenoviral particles responsible for the common cold, which can make recipients ill, said Gustavo Mendes, Anvisa’s manager of medicines and organic products, in an interview Monday.

Mr Mendes said Brazil also had doubts about the methodology used in Sputnik V̵

7;s clinical trials and whether the batch of doses Brazil would receive would be identical to the shots tested in those studies.

“It’s a matter of both safety and efficiency,” Mr Mendes said.
