Today, people can be vaccinated against the human papillomavirus, or HPV, to prevent high-risk types of the virus that can lead to cervical cancer, anal cancer, external genital cancers, and genital warts.

The genital wart vaccine is the first vaccine developed and approved to prevent cancer.

In the following, we will talk about the effects of this vaccine and how to inject it. We will also talk about how long it takes for the side effects of the HPV vaccine to go away.

What is the HPV vaccine?

The brand name of these vaccines is Gardasil. Gardasil is a four-dose vaccine that means it can protect your body against four high-risk types of genital wart virus.

These four types of genital wart virus are:

  1. Hpv-6
  2. Hpv-11
  3. Hpv-16
  4. Hpv-18

Which are responsible for causing 70% of cervical cancers, 80% of anal cancers, 40% of cancers of the external genitalia (vulvar cancer) and 90% of genital warts.

The newer generation of HPV vaccines, in addition to the above four types, also covers five types of genital wart virus. This vaccine is called Gardasil 9.


What does the HPV vaccine not do?


Gardasil vaccine or HPV vaccine injection time

The vaccine was initially recommended for girls 9 to 25 years old (Gardasil vaccine prevented ninety-nine percent of genital warts in this age group), but today it is known that women up to the age of 45 also benefit from this vaccine. However, they are not infected with any of the types of HPV in the vaccine.

The tetravalent vaccine can also be used in men 9 to 25 years of age


Injectable dose of vaccine

Two or three doses

Interval of injections in two doses: the second dose six to twelve months after the first dose is injected

Interval of injections in three doses: the second dose is injected two months after the first dose and the third dose, six months after the first dose.


The vaccine is given in three doses as follows:

The second dose will be two months after the first injection and the third dose will be six months after the first injection.


What are the side effects of the HPV vaccine?

who should not be vaccinated with Gardasil vaccine?




Headache, fever, lightheadedness and fainting that are quite transient, and muscle pain and fatigue


Long-term side effects may also occur following injection of Gardasil:

Around 2009, a study showed that a number of girls receiving the vaccine developed a series of neurological symptoms within a few weeks of receiving the vaccine.

However, in 2019 studies, no special conditions were observed for the recipients of Gardasil 9 vaccine and there was no specific immunosuppressive complication.


How long does it take for the HPV vaccine side effects to go away?

Local or non-local side effects such as swelling, redness and pain at the injection site will improve in about forty-eight hours, and side effects such as headache, fever, etc. will not last long.

It is not yet known how long the immunity developed by the Gardasil vaccine lasts, but we must say that it is better not to miss the chance to be safe against the deadly cancers mentioned above, for fear of the very rare side effects of the HPV vaccine.
