The main drawback of coronavirus vaccines, which are currently in clinical trials around the world, is the need to inject twice. Anch Baranova, professor at the School of Systems Biology at George Mason University, pointed out such a minus in an interview with RIA Novosti.
“There is a great risk that people will receive the first vaccine, but they will either forget to come for the second injection, or they read some opponents of vaccination and will not come,” the biologist explained. If people only get the first shot and not the second, the impact of mass vaccination campaigns will be diminished, she said.
At the same time, as Baranova added, Chinese scientists have created a vaccine with one stage, but its effectiveness has not yet been established.
Earlier, Kremlin spokesman Dmitry Peskov announced the start of mass vaccinations in Russia. According to him, vaccination will begin before the New Year and will take place in stages, taking into account the geographic characteristics of the country.
To date, two vaccines against COVID-19 have been registered in Russia. The first drug to be registered was Sputnik V. On October 14, President Vladimir Putin announced the registration of EpiVacCorona from the Vector Center. The country is also developing a third drug – this is being done by the Chumakov Center. It is planned that the mass production of the vaccine will begin in February 2021.
