Article Synopsis
- The SARS-CoV-2 virus mutates continuously, leading to new variants like Omicron, which has reduced the effectiveness of vaccines worldwide.
- The study evaluated the Sputnik V vaccine's effectiveness against several SARS-CoV-2 variants using various research methods on transgenic mice.
- Results showed that while Sputnik V generates a strong immune response, its efficacy is significantly lower against the Omicron variant, highlighting the need for ongoing monitoring and potential development of new vaccines.
The data on the structure of the M genome segment of CCHF virus strains from Russia and Central Asia (Tajikistan) are presented. Data obtained have been compared with other available published sequences of the middle segment of strains from China, Nigeria, and Pakistan. It has been found that all the known strains can be divided into four genetic groups, based on the nucleotide sequence of the M genome segment and an amino acid sequence of the glycoprotein precursor it encodes, whereas VLG/TI29414 and STV/HU29223 strains from Russia form a separate group.
