Yes. The HPV vaccine does not prevent every case of HPV. It targets the virus types responsible for most HPV-related cancers and genital warts, but it does not cover all of them. It also cannot treat an infection you already have. So a vaccinated person can still get HPV — though the risk is much lower for the types that matter most.
Can You Still Get HPV Even With the Vaccine?
You can. The vaccine is not a shield against all HPV. It is a targeted tool against the types most likely to cause cancer and genital warts.
There are more than 200 known types of human papillomavirus. The vaccines used in the United States protect against the types responsible for the large majority of HPV-related cancers and genital warts. That leaves other types circulating that the vaccine does not cover.
There is a second reason. The vaccine prevents new infections. It does not clear an infection you already had before vaccination. If you were exposed to a covered type before your shots, the vaccine will not remove it.
Neither of these facts makes the vaccine weak. It makes it specific. Understanding what it does and does not do is the key to understanding your actual risk.
What Does the HPV Vaccine Actually Protect Against?
The vaccine protects against the HPV types that cause the most disease. The current U.S. vaccine, Gardasil 9, covers nine types: 6, 11, 16, 18, 31, 33, 45, 52, and 58.
Types 16 and 18 are the most important. Together they account for the majority of cervical cancers worldwide. Types 6 and 11 cause most genital warts and a condition called recurrent respiratory papillomatosis, which causes wart-like growths in the airway.
The remaining five types add coverage against additional cancer-causing strains. The vaccine’s design is not random. It targets the types that do the most harm.
What it does not cover is the long tail of other HPV types. Most of these are harmless or cause minor issues. Some can cause cancer, but they are far less common drivers of disease.
This is why the vaccine is best understood as a high-impact intervention, not a complete barrier. It removes the biggest threats. It does not remove every threat.
Does the Vaccine Treat an Infection You Already Have?
No. The HPV vaccine is preventive, not therapeutic. It cannot clear an infection that is already present.
This is a common point of confusion. The vaccine works by prompting your immune system to make antibodies before you encounter the virus. Once an infection is established, those antibodies do not eliminate it.
HPV is also unusual in how it behaves. Most infections clear on their own within one to two years as the immune system handles them. The concern is the infections that persist. Persistent infection with a high-risk type is what can lead to cell changes and, over many years, cancer.
Because the vaccine cannot treat existing infection, timing matters. The vaccine is most effective when given before any exposure to the virus. That is why it is recommended in early adolescence, before most people become sexually active.
This does not mean it is useless for older people. It means the benefit is different. Someone who has not been exposed to a covered type can still gain protection from the vaccine at any age within the recommended range.
How Common Is HPV After Vaccination?
HPV infection is still possible after vaccination, but the types that cause the most cancer are far less likely to appear. This is the central point, and it is well supported.
Research consistently shows that the vaccine sharply reduces new infections with the covered types. Studies tracking vaccinated populations have found large drops in infections with types 16 and 18, and corresponding reductions in precancerous cervical changes.
The effect on genital warts has been especially clear. In countries with high vaccination coverage, rates of genital warts have fallen substantially, including in groups that were not vaccinated themselves — a pattern consistent with reduced transmission.
What remains is the rest of the HPV family. A vaccinated person can still acquire a non-covered type. Most of the time this causes no symptoms and clears on its own. In a small number of cases, a non-covered high-risk type can persist and lead to cell changes.
So the honest picture is this: vaccination lowers your risk a great deal for the types that matter most, but it does not bring your risk to zero.
Why Doesn’t the Vaccine Cover Every HPV Type?
Because covering every type is not practical, and it is not necessary to prevent most disease.
There are over 200 HPV types. Many do not cause health problems in humans. Building a vaccine against all of them would be enormously complex, and the added benefit would be small compared with the types already covered.
Vaccine design also involves trade-offs. Adding more types means more manufacturing complexity and potentially different immune responses. The current approach targets the types with the greatest public health impact.
This is a deliberate strategy used across vaccinology. You do not need to block every version of a pathogen to prevent most of the harm. You block the ones that cause the most damage.
It is worth noting that HPV types are not equally dangerous. The distinction between low-risk and high-risk types is real and well established. Low-risk types can cause warts but are not linked to cancer. High-risk types are the ones tied to cancer, and the vaccine targets the most common of these.
Do You Still Need Pap Tests and HPV Screening If You’re Vaccinated?
Yes. Screening recommendations do not change based on vaccination status.
This surprises many people. If the vaccine does not cover every cancer-causing type, and if it cannot treat an infection you already had, then screening remains necessary to catch cell changes that could progress.
Cervical cancer screening — whether by Pap test, HPV test, or both together — is designed to find abnormal cells or high-risk infections before they become cancer. The vaccine reduces how often those problems occur. It does not remove the need to look for them.
Screening guidelines have evolved over time, and the recommended intervals and starting ages have changed. Because these recommendations are updated periodically by national organizations, the most reliable approach is to follow the current guidance from your clinician rather than relying on a fixed number from memory.
The same logic applies to other HPV-related concerns. The vaccine lowers risk. It does not replace regular care.
What This Means for Your Actual Risk
Your risk after vaccination is lower, not zero. How much lower depends on which types you encounter and whether you were exposed before vaccination.
The vaccine’s greatest strength is against the types that cause most HPV-related cancers. That is a meaningful reduction in risk, and it is why vaccination is recommended so broadly.
What it cannot do is make you invulnerable to a virus with more than 200 types. No vaccine against HPV does that. Anyone who tells you otherwise is overstating what the evidence shows.
The practical takeaway is straightforward. Get vaccinated if you are within the recommended age range and have not been. Keep up with recommended screening. And understand that the vaccine and screening work together — one lowers your chance of infection with the most dangerous types, the other catches problems early if they appear.
That combination is what actually reduces HPV-related cancer risk. Neither piece does the whole job alone.
Frequently Asked Questions
Can you still get HPV if you’ve had the vaccine?
Yes. The vaccine does not cover every HPV type, and it cannot treat an infection you already had before vaccination. It does sharply reduce your risk from the types most likely to cause cancer and genital warts.
Does the HPV vaccine protect against all types of HPV?
No. The U.S. vaccine covers nine types, including the ones responsible for most HPV-related cancers and genital warts. More than 200 HPV types exist, and the vaccine does not cover all of them.
Can the HPV vaccine cure an HPV infection I already have?
No. The vaccine is preventive and cannot clear an existing infection. It works by helping your immune system recognize the virus before you encounter it.
Do I still need Pap smears after the HPV vaccine?
Yes. Screening recommendations do not change based on vaccination status, because the vaccine does not cover every cancer-causing type. Follow the current screening guidance from your clinician.
