Why is there an age limit for hpv vaccine?

Hpv vaccine has a certain age limit, mainly considering the limited safety and production capacity of the vaccine, so the age limit is set and calculated according to the date of birth on the ID card. There is an age limit for hpv vaccine, and the sooner you get it, the better. The best immunization age of HPV vaccine in the world is the age before sexual intercourse, which is defined as 9 ~ 14 years old. Let's see why there is an age limit for hpv vaccines. 1. Why is there an age limit for hpv vaccine?

Hpv vaccine to prevent cervical cancer is the gospel of female friends, but it should be noted that hpv vaccine has an age limit, and it is not allowed to be vaccinated beyond a certain age. Why?

In fact, hpv vaccine is not over-age, and most countries and regions only recommend that hpv vaccine be vaccinated at the age of 9-45, but the reason why the country stipulates the age limit is mainly because:

1, hpv vaccine is on the market very quickly, and Chinese mainland lacks the support of clinical data, so it may choose a relatively conservative age range.

2. It is better to vaccinate hpv vaccine at the right age, especially if the vaccine production capacity is limited, it will be more difficult to let go of the age limit.

In short, the age limit for hpv vaccination is mainly based on safety and rationality, and then a decision is made.

Second, does the age of cervical cancer vaccination mean one year old?

There is an age limit for cervical cancer vaccine, but many friends don't know what this age is, whether it is a lunar birthday or a solar birthday, a natural year or something. In fact, the age of cervical cancer vaccination mainly depends on the ID card.

No matter when your birthday is actually, no matter whether you were born before or after your ID card, as long as your ID card meets the age requirements, you can get the corresponding hpv vaccine. Even if you are 26 years old today according to the date on your ID card, you can get a nine-valent hpv vaccine.

In addition, some people are less than 26 years old after the first injection, and they are over 26 years old after the second and third injections. According to the regulations of the CDC, they can continue to play as long as they are under the age of 26, that is, before the age of 27.

Third, the age of hpv vaccine?

There are three kinds of hpv vaccines, bivalent hpv vaccine is suitable for 9-45 years old, tetravalent hpv vaccine is suitable for 20-45 years old, and nonavalent hpv vaccine is suitable for 16-26 years old. This is the prescribed age limit. In fact, the sooner hpv vaccine is given, the better.
