The original HPV vaccine was first given in the major vaccine studies in 2003. The latest research shows the vaccine still offers close to 100% protection more than 10 years after it was received, and this protection shows no sign of weakening.
To date, protection against infections with the targeted HPV types has been found to last for at least 10 years with Gardasil (18), up to 11 years with Cervarix (17), and at least 6 years with Gardasil 9 (19).
For this reason, older teens and adults should get three doses for best protection. If someone age 9–14 years received two doses of HPV vaccine less than 5 months apart, should they get a third HPV vaccine dose? Yes.
Because the HPV vaccine does not protect against all types of HPV, it is possible that a fully vaccinated person could be infected with a type of HPV that is not contained in the vaccine. Most people will clear any type of HPV infection— but it may take months to do so.
HPV vaccines are highly immunogenic.
More than 98% of recipients develop an antibody response to HPV types included in the respective vaccines 1 month after completing a full vaccination series. However, there is no known serologic correlate of immunity and no known minimum titer determined to be protective.
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.
Even if you already have one strain of HPV , you could still benefit from the vaccine because it can protect you from other strains that you don't yet have. However, none of the vaccines can treat an existing HPV infection. The vaccines protect you only from specific strains of HPV you haven't been exposed to already.
Yes, vaccinated women will still need regular cervical cancer screening because the vaccine protects against most but not all HPV types that cause cervical cancer. Also, women who got the vaccine after becoming sexually active may not get the full benefit of the vaccine if they had already been exposed to HPV.
Studies suggest that HPV vaccines offer long-lasting protection against HPV infection and therefore disease caused by HPV infection. Studies of the bivalent and quadrivalent vaccines have followed vaccinated individuals for more than 10 years and have found no evidence of protection decreasing over time.
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.
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.
It is important to use a condom from start to finish of every sex act, including oral and anal sex. HPV is transmitted by skin-to-skin contact. Because HPV can infect areas that are not covered by the condom, condoms will not fully protect you against HPV, but condoms do help in HPV prevention.
Often, HPV warts will appear three to six months after sexual relations with an infected person; or they may take months to appear; or they may never appear. Likewise, the interval between an infection with HPV and a cervical smear abnormality can vary from months to decades.
Human Papillomavirus (HPV) Infection
HPV is the most common STI in the United States, but most people with the infection have no symptoms. HPV can cause some health effects that are preventable with vaccines.
Of the more than 100 types of HPV, about 40 types can spread through direct sexual contact to genital areas, as well as the mouth and throat. Oral HPV is transmitted to the mouth by oral sex, or possibly in other ways. Many people are exposed to oral HPV in their life.
Most men who get HPV never have symptoms. The infection usually goes away by itself. But, if HPV does not go away, it can cause genital warts or certain kinds of cancer. Talk to your healthcare provider about anything new or unusual on your penis, scrotum, anus, mouth, or throat.
The HPV vaccine is marketed to younger people, because of how prevalent the virus is as soon as you become sexually active. “HPV infection is very common and it's estimated that over 80 percent of sexually active adults, ages 18-65, have been infected with at least one strain, even if they never knew it,” says Dr.
ACIP does not recommend HPV vaccination for adults older than age 26 years. ACIP recommends HPV vaccination based on shared clinical decision making for individuals ages 27 through 45 years who are not adequately vaccinated. [1] HPV vaccines are not licensed for use in adults older than age 45 years.
HPV vaccine is free under the National Immunisation Program through school-based programs for children aged 12-13.
All three HPV vaccines protect against HPV types 16 and 18 that cause most HPV cancers. Since late 2016, only Gardasil-9 (9vHPV) is distributed in the United States. This vaccine protects against nine HPV types (6, 11, 16, 18, 31, 33, 45, 52, and 58).
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.
“By the time you vaccinate individuals in their 30s and 40s, many have already been exposed to HPV, so the health benefit really decreases at these older ages,” she said. “It's also important to emphasize that cervical cancer screening remains an effective and cost-effective way to protect women from cervical cancer.”
The HPV vaccine was originally approved for females ages 9 through 26. 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.
