Brazil defends the decision to reject Russia’s Covid-19 vaccine on the grounds of safety and efficacy



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 shot for emergency use, saying Russia lacks vaccine experience and was defensive in its response to the Agency.

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

Brazil is concerned that the vaccine may contain active adenovirus particles that are responsible for colds, which can make recipients sick, Gustavo Mendes, Anvisa’s medical and biological product manager, said in an interview on Monday.

Sir. Mendes said Brazil was also in doubt about the method used in Sputnik V̵

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

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