Russia develops Covid-19 vaccine that does not require injection

The vaccine is being developed by scientists at the Institute of Experimental Medicine in St. Petersburg and is administered orally, in aerosol or droplet form, according to Vladimir Chekhonin, vice president of the Russian Academy of Sciences.

The antigens in these preparations are encapsulated in microcapsules, which protect them from digestive enzymes. The goal is to clone a gene encoding the S protein of the SARS CoV-2 virus (which is the main antigen that stimulates neutralizing antibodies). As a result, the gene is inserted into the coding region of the surface pilus of the bioengineered bacteria and a bacterium is formed with the virus's immunogenic protein on its surface. To date, preclinical trials of this vaccine are underway.

Currently, Russia is developing nine different vaccines that can protect the human body from the SARS CoV-2 virus. Six are being developed by the Vector State Research Center for Virology and Biotechnology under the Federal Service for Supervision, Protection of Consumer Rights and Health of the Russian Federation, two others are being developed by the Biocad Company, one of which is a joint research with the Institute of Experimental Medicine in St. Petersburg. The ninth vaccine is being developed by the St. Petersburg Research Institute of Vaccines and Serums.

Previously, scientists at the National Center for Virology and Biotechnology "Vector" also developed a Covid-19 vaccine that can be administered into the body by dropping it into the nose. This vaccine has been successfully tested in preclinical trials.

As of June 2, Russia recorded 42,3741 people infected with Covid-19, an increase of 8,863 cases compared to the previous day, 186,985 people recovered, 5,037 people died./.
