A new vaccine will save from human papillomavirus
As it is known, human papillomavirus (HPV) virus is very common. It is transmitted sexually. Due to HPV, warts appear and the risk of cervical cancer increases substantially. As UPI.com notices, about 300,000 people die from cervical cancer each year (more than 80% die in developing countries).
There are more than 100 types of HPV, but only 13 of them are associated with the development of cancer. HPV 16 and HPV 18 present in most cases of cervical cancer (approximately 70%). Currently, there are two vaccines against HPV - Cervarix and Gardasil. They successfully prevent an infection with HPV 16 and HPV 18. Gardasil also protects against HPV 6 and HPV 11. However, vaccines do not fight against other types of viruses.
The new study involved 14215 women aged 16 to 26 years. Scientists have found that the new HPV vaccine, 9vHPV, prevents infection with HPV 16, 18, 6, 11, 31, 33, 45, 52 and HPV 58. The effect was stable. Compared to Gardasil, 9vHPV vaccine reduced the risk of infection with HPV 31, 33, 45, 52 and HPV 58 by 97.7%. According to the scientists, the new vaccine can prevent about 90% of cases of cervical cancer.
