[Nine-valent HPV vaccine - new generation of HPV vaccine]
Objective:
To evaluate current knowledge about new generation of HPV vaccine - nine-valent vaccine Gardasil9.
Design:
Review article.
Results:
The nine-valent vaccine against HPV 6/11/16/18/31/33/45/52/58 could improve efficacy of quadrivalent vaccine from 70 to 90 percent for cervical cancer. In addition this vaccine has covered around85-90% of HPV-related vulvar, vaginal and anal cancers. Efficacy and immunogenicity against HPV 6/11/16/18 is the same as for quadrivalent vaccine. Efficacy against HPV 31/33/45/52/58 associated lesions is 97%.
