What are the components of the HPV vaccine?

The ingredients are proteins of HPV Types 6, 11, 16, and 18, amorphous aluminum hydroxyphosphate sulfate, yeast protein, sodium chloride, L-histidine, polysorbate 80, sodium borate, and water for injection.

What is the science behind the HPV vaccine?

Like other immunizations that guard against viral infection, HPV vaccines stimulate the body to produce antibodies that, in future encounters with HPV, bind to the virus and prevent it from infecting cells. The current HPV vaccines are based on virus-like particles (VLPs) that are formed by HPV surface components.

How does the immune system response to HPV vaccine?

HPV vaccines are proven safe and effective. The vaccine helps the body develop immunity to HPV by imitating an HPV infection. When the vaccine is injected into your arm, your immune system responds as if this was the real virus and makes antibodies to fight it off.

What kind of vaccine is the HPV vaccine?

About HPV Vaccines 9-valent HPV vaccine (Gardasil-9 [23 pages] ) is a non-infectious recombinant vaccine prepared from the purified virus-like particles (VLPs) of the major capsid (L1) protein of HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58.

Does the HPV vaccine last for life?

How long does vaccine protection last? Research suggests that vaccine protection is long-lasting. Current studies have followed vaccinated individuals for ten years, and show that there is no evidence of weakened protection over time.

Should boys get HPV vaccine?

HPV vaccine is cancer prevention. Vaccinate your son or daughter when they are 11 or 12 to protect them against HPV cancers later in life. Learn why all 11-12 year old boys and girls should get the HPV vaccine. HPV can cause six types of cancer in men and women. HPV vaccination can prevent these cancers.

What happens if you get the HPV vaccine twice?

People who have received one dose of the HPV vaccine may have some protection, but the additional dose or doses (depending upon age) offer additional protection. Further, if you or your partner were already infected with a type of HPV, the vaccine will not prevent transmission of that HPV type.

What are the 3 types of HPV vaccines?

Three HPV vaccines—9-valent HPV vaccine (Gardasil 9, 9vHPV), quadrivalent HPV vaccine (Gardasil, 4vHPV), and bivalent HPV vaccine (Cervarix, 2vHPV)—have been licensed by the U.S. Food and Drug Administration (FDA). All three HPV vaccines protect against HPV types 16 and 18 that cause most HPV cancers.

When was the HPV vaccine invented?

Since HPV vaccines were first introduced in the U.S. in 2006 there have been changes in the range of protection they offer and the dosing regimen. The vaccines were originally recommended only for girls and young women and were subsequently broadened to include boys and young men.

Does HPV weaken the immune system?

HPV can also induce immune evasion of the infected cells, which enable the virus to be undetectable for long periods of time. The induction of immunotolerance of the host’s immune system by the persistent infection of HPV is one of the most important mechanisms for cervical lesions.

Do you need HPV vaccine if you are married?

“If you are married, monogamous, and 35 — there’s probably no reason to run out and get the HPV vaccine. But if you’re dating and having new partners, and are at risk for acquiring new infections, it would be worth having a discussion with your provider,” Eckert said.

Can I get HPV vaccine if I am over 45?

Now, men and women up to age 45 can get vaccinated. US health officials have expanded the recommended age range for people receiving the HPV vaccine to protect against several types of cancer to people in their mid-40s.

Can you clear HPV after 30?

There is no cure for HPV, but 70% to 90% of infections are cleared by the immune system and become undetectable. HPV peaks in young women around age of sexual debut and declines in the late 20s and 30s. But women’s risk for HPV is not over yet: There is sometimes a second peak around the age of menopause.

When is it too late for HPV vaccine?

HPV vaccination is not recommended for everyone older than age 26 years. Some adults age 27 through 45 years who were not already vaccinated might choose to get HPV vaccine after speaking with their doctor about their risk for new HPV infections and possible benefits of vaccination for them.

Why was the HPV vaccine discontinued?

They cited a lack of adequate long-term testing of the vaccine, unproven efficacy and disturbing news of adverse side effects such as neurological disorders.

What are the negatives of getting the HPV vaccine?

HPV vaccines can cause pain, swelling, and redness where the shot was given, as well as headaches, tiredness, and nausea. The most common serious side effects of HPV vaccination are dizziness and fainting.

Can HPV vaccine trigger autoimmune disease?

In this nationwide study, the quadrivalent HPV vaccination was not associated with increased incidence of new-onset autoimmune disease in girls and women with pre-existing autoimmune disease.

Why are there 3 shots for HPV vaccine?

Preteens get two doses and teens 15 and older get three doses because preteens make more antibodies after they get the HPV vaccine than older teens or young adults. Three doses also are recommended for preteens and teens age 9 years and older who have certain immunocompromising conditions.

Can I pass HPV to my child by sharing drinks?

HPV is passed through skin-to-skin contact, not through bodily fluids. Sharing drinks, utensils, and other items with saliva is very unlikely to transmit the virus.

How did I get HPV if I am married?

You can get HPV by having vaginal, anal, or oral sex with someone who has the virus. It is most commonly spread during vaginal or anal sex. It also spreads through close skin-to-skin touching during sex. A person with HPV can pass the infection to someone even when they have no signs or symptoms.

Why can’t I get HPV vaccine after 26?

What about people older than 26? The HPV vaccine is most effective in early adolescence, but this starts to decrease by age 18. Because of this, it is unlikely to provide much benefit for cancer prevention as people get older. The ACS does not recommend HPV vaccination for persons older than age 26 years.

Can you still get HPV if you have had the vaccine?

There is a small chance that someone might still get genital warts after having all their HPV vaccine shots. The vaccine protects against 90% of the HPV strains that cause genital warts. But there are lots of different strains (types) of HPV and the vaccine cannot protect against them all.

Should I get HPV vaccine if I am over 26?

Vaccination is not recommended for everyone older than age 26 years. Some adults ages 27 through 45 years might decide to get the HPV vaccine based on discussion with their clinician, if they did not get adequately vaccinated when they were younger.

How long did it take to make HPV vaccine?

After seven years of design and testing, the first human trials for the vaccine, named Gardasil, were completed. This vaccine prevented four high-risk HPV types (HPV 6, 11, 16, and 18), which would target over 70% of cervical cancer cases.

Are all warts caused by HPV?

Each person’s immune system responds to the HPV virus differently, so not everyone who comes in contact with HPV develops warts.
