The nasal spray is to be applied in two doses in a clinic in St Petersburg, according to the document published on the state register of medicines, which did not provide the planned timing of the clinical tests.
President Vladimir Putin said on Tuesday that Russia needed to speed up its vaccination campaign against Covid-19 as the country recorded its highest single-day death toll since the start of the pandemic.
Russian authorities said in June that they had a nasal spray vaccine suitable for children aged 8-12, which had been tested, and the plan was to launch the new product in September.
