The first clinical trials were completed with a second Russian vaccine, a health official said Wednesday, bringing it closer to the registry under the Russian focus of approving vaccines for emergency use before starting late-stage trials to determine if they are effective.
Early trials provide information on safety, although rare side effects may not be detected until much larger trials are carried out at an advanced stage. Subsequent trials, known as Phase 3, are the only means of determining whether a vaccine actually protects against the coronavirus.
Russia registered its first Covid-19 vaccine, one based on the common cold viruses, in August, and now offers a small number of doses outside of trials to people at high risk of infection, such as healthcare workers. Western vaccine experts criticized the Russian approach as potentially dangerous.
Anna Papova, director of Rospotrebnadzor, a Russian agency that regulates health care, said on Wednesday that researchers had completed the first clinical trials of a different vaccine, based on proteins that mimic those of the coronavirus.
Ms Papova defended the Russian regulatory approach, saying it was based on a long history of Soviet vaccine development. “Russian vaccines deserve absolutely no criticism,” he said.
His agency said earlier this month that it planned to register the second vaccine, made by Vektor, a Siberian laboratory that studied biological weapons during the Cold War, by October 15. A third Russian vaccine, made by the Chumakov Institute in Moscow and based on inactivated coronavirus, is now in early-stage trials.
