MOSCOW (AP) — Russia is boasting that it’s about to be the first country to approve a COVID-19 vaccine, with mass vaccinations planned as early as October using shots that are yet to complete clinical trials. But scientists worldwide are sounding the alarm that the headlong rush could backfire and point to ethical issues that undermine confidence in the Russian studies. Moscow sees a Sputnik-like propaganda victory, recalling the Soviet Union’s launch of the world’s first satellite in 1957. But the experimental COVID-19 shots began first-in-human testing on a few dozen people less than two months ago, and there’s no published scientific evidence yet backing Russia’s late entry to the global vaccine race, much less explaining why it should be considered a front-runner.
