Nine-valent refers to the nine-valent HPV vaccine, and the latest age for women born in 1996 to receive the vaccine is 26 years old. The HPV vaccine is intended for people between the ages of 16 and 26, so if you are within the age range for the vaccine, you can get it. In addition, the nine-valent HPV vaccine is not a mandatory vaccination, and voluntary vaccination is sufficient. The nine-valent HPV vaccine protects against HPV subtypes 6, 11, 16, 18, 45, 52 and other subtypes, and studies have shown that it can prevent more than 90% of cervical cancers. Usually, three doses of the HPV vaccine are required, and the entire course of the vaccine should be administered within one year. If the vaccine is not administered on time due to special circumstances, it is sufficient to continue to receive the remaining doses without having to start all over again. To summarize, if you are interested in receiving the HPV vaccine, it is recommended to understand the applicable population and precautions beforehand.
