The vaccine from Russia is not to be launched in August, as the participants who received the vaccine in June 2020 are to be monitored for 180 days.
There is no official confirmation from the Russian government regarding the launch of the vaccine in August. The latest announcement was on July 2 about the BRICS (Brazil, Russia, India, China, and South Africa) STI Framework Programme's dedication to research and development of drugs against COVID-19.
The World Health Organization has listed the vaccine, named Gam-COVID-Vac Lyo, as one of the candidate vaccines under clinical evaluation. The Week in its article covers how the media story about Russia having finished human trials of the vaccine is untrue.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
