Influenza is well-known to have a considerable influence on the healthcare system; therefore, vaccination plays a significant role in dealing with severe consequences. Close attention is paid to the development of tetravalent adjuvanted vaccines containing antigens of two influenzas A subtypes (H1N1, H3N2) and two influenza B subtypes (Victoria, Yamagata) to increase the effectiveness of influenza prevention. In this work, we present the results of an animal study of an innovative subunit tetravalent candidate influenza vaccine with the addition of betulin as an adjuvant, TetraFluBet. The study was conducted using female BALB/c mice, male and female mongrel rats, and guinea pigs. TetraFluBet was injected intraperitoneally twice in a 14-day interval prior to intranasal infection with 100LD50. Sub-chronic toxicity was assessed by immunohistochemistry of extracted organs and by hematolog.. View More»
