The children’s vaccine Encevir Neo for the prevention of tick-borne encephalitis, developed by SPA Microgen (part of the Nacimbio holding company of Rostec State Corporation), has received a registration certificate in the Republic of Belarus (LP No.001361-GP-BY).

Encevir Neo is a Russian vaccine designed to protect against tick-borne encephalitis in children aged 3-17. Its efficacy and safety have been confirmed through clinical trials conducted in 2011-2012 at four research centers in Moscow, St. Petersburg, Perm, and Omsk, involving 320 children.

In Russia, Encevir Neo is listed as a vital and essential medicine for medical use. The drug is commonly used for vaccinating the population as part of the calendar of preventive vaccinations against epidemic indications.

In order to prevent tick-borne encephalitis, the Nacimbio holding company supplied only the Encevir vaccine for adults to the Republic of Belarus. The annual supply of this vaccine is approximately 18,000 doses. The new vaccine will be delivered to Belarus alongside the adult drug.

“We not only produce complete-cycle vaccines, but we also systematically work to expand the geographical presence of our products in various countries. In addition to Belarus, Microgen’s products are also registered in Kyrgyzstan, Mongolia, Uzbekistan and Azerbaijan. Our goal is to help prevent viral infections in the member states of the Eurasian Economic Union. We believe that the Encevir Neo children’s vaccine for tick-borne encephalitis will improve prevention of this dangerous disease in Belarus and prevent negative effects of tick bites on adults and children,” said Andrei Zagorsky, CEO of Nacimbio.

Tick-borne encephalitis is a significant health concern in Belarus. Long-term epidemiological monitoring of the infection’s spread in the country indicates a trend towards an increase in incidence. Simultaneously, due to climate change, the duration of the tick activity period, as well as the risk of contracting tick-borne encephalitis has increased to 10 months per year. According to the Russian Research Institute of Health, in 2024, more than 25 thousand people visited medical institutions in Belarus after being bitten by ticks.
