Why is the age limit for 1 and 9-valent vaccines limited to 25 years old?
The age limit for the 9-valent vaccine is women aged 16-26. There are three main reasons:
1. The pre-market clinical trials of the nine-valent vaccine included women aged 16-26. Data from overseas clinical studies of the vaccine in this age group, as well as in East Asia The protective efficiency against persistent infection demonstrated in the population suggests that the benefits outweigh the risks.
2. The probability of female behavior among children aged 9-15 in the country is relatively low. The vaccinators aged 9-15 only conducted an immunization trial. This experiment included East Asian Chinese Clinical data on the population are limited, so the appropriate age for vaccination is not placed in the 9-15 age group.
3. Many women over 26 years old have a history of virus exposure. There is currently no evidence to prove that the nine-valent vaccine is effective in this age group after virus exposure. Crowds are protective.
2. Who is not suitable for vaccination with the nine-valent cervical cancer vaccine
The nine-valent cervical cancer vaccine is the latest type of cervical cancer vaccine. It includes nine viruses, covers a wider range of viruses, and has better efficacy than quadrivalent and bivalent vaccines. Meanwhile, both men and women can receive the vaccine. Currently, this vaccine can only be used in people aged 16-26 years because there is currently clinical data to support this group. Currently, only Hong Kong and abroad can receive this vaccine, but China has not yet entered this vaccine.
OK, this is the end of the content about why people after the age of 26 cannot use nine prices and why nine prices are limited to those aged 25. I hope it will be helpful to everyone.
