Many of the adults who come to us in Patong missed HPV vaccination as teenagers because the rollout in their home country happened too late, or stopped at age 18, or only covered girls. Catch-up vaccination of adults is one of the most useful preventive things we do, and Gardasil 9 is stocked on site so the first dose can usually be given the same day you walk in.
What HPV is and why vaccination matters
Human papillomavirus is a family of more than 150 related viruses, of which around 14 types are classified as high-risk because they can cause cancer over years to decades. Two low-risk types, 6 and 11, cause around 90 percent of genital warts. The high-risk types, especially 16 and 18, cause nearly all cervical cancers, around 90 percent of anal cancers, 60 to 70 percent of cancers at the back of the throat and base of the tongue, and a meaningful share of vulvar, vaginal and penile cancers. HPV is transmitted skin-to-skin during sexual contact, including oral and manual contact, which is why condoms reduce but do not eliminate risk. Most sexually active people are exposed to at least one HPV type in their lifetime, and the body clears most infections within two years, but the small fraction that persists is what drives cancer risk decades later. Gardasil 9 covers types 6, 11, 16, 18, 31, 33, 45, 52 and 58, which together account for around 90 percent of HPV-related cancers and 90 percent of genital warts. The vaccine is a non-infectious virus-like particle vaccine, meaning it contains no viral DNA and cannot cause HPV infection.
Who should be vaccinated, and at what age
The routine recommendation from the US Advisory Committee on Immunization Practices (ACIP) and most European programmes is HPV vaccination at age 11 or 12, with the option to start at age 9, and catch-up vaccination through age 26. For adults aged 27 to 45, vaccination is offered on a shared decision-making basis: people with new partners, men who have sex with men, people living with HIV, those with prior abnormal Pap results, and anyone whose risk profile has changed since adolescence usually benefit. Beyond age 45 the formal evidence is thinner, but we vaccinate selected adults case-by-case after a conversation about likely benefit. Men benefit too: HPV causes anal, penile and oropharyngeal cancers in men, and unvaccinated men also act as a reservoir that infects future partners. Gardasil 9 is licensed for males and females from age 9. Vaccination is safe in breastfeeding mothers, and although it is not contraindicated in pregnancy, we usually defer remaining doses until after delivery and resume the schedule then.
Dose schedule by age and health status
| Age band or status when starting | Doses | Interval | Notes |
|---|---|---|---|
| Age 9 to 14 | 2 doses | 0 and 6 to 12 months | Best window for full immune response, ideally before sexual debut. |
| Age 15 to 26 | 3 doses | 0, 1 to 2 months, 6 months | Standard catch-up. Highly effective even after some HPV exposure. |
| Age 27 to 45 | 3 doses | 0, 1 to 2 months, 6 months | Shared decision-making. Still useful for new partners, MSM, immunocompromised. |
| Immunocompromised or HIV positive, any age | 3 doses | 0, 1 to 2 months, 6 months | Three doses regardless of age, including transplant recipients. |
| Schedule interrupted | Complete the series | No need to restart | Resume from where you stopped, even if years late. |
Safety profile and the myths we get asked about
HPV vaccine has one of the strongest safety records of any modern vaccine, with more than 270 million doses distributed worldwide since 2006 and 15 years of post-marketing surveillance. The common side effects are local: a sore arm for a day or two, mild redness or swelling at the injection site, occasionally a low-grade fever or headache. The most clinically relevant rare event is fainting (vasovagal syncope), which is more common in adolescents and is the reason we ask every patient to stay seated for 15 minutes after the injection. Anaphylaxis is very rare, around 1.7 per million doses, and a documented severe allergic reaction to a first dose is one of the few reasons we would not give a second. Large studies have specifically looked for, and not found, any link between HPV vaccination and infertility, premature ovarian insufficiency, autoimmune disease, autism, chronic fatigue or postural orthostatic tachycardia syndrome. Where claims about these conditions circulate on social media, they have been investigated, repeatedly, and not confirmed.
Does vaccination work after possible exposure?
Yes, in almost everyone, because almost no one has been exposed to all nine HPV types covered by Gardasil 9. The vaccine is most effective before any sexual contact, when no HPV types have been acquired, which is why programmes target age 11 to 12. After sexual debut, the vaccine still protects against every type the person has not already met, and it does not have to be all-or-nothing. We see this often in adults in their 30s and 40s: even patients who have had a previous abnormal Pap result, a genital warts episode, or a known HPV infection still gain meaningful protection against the other types and against re-infection at new sites such as the throat or anus. Vaccination after a confirmed HPV-related lesion (warts, CIN, abnormal Pap) does not treat the existing infection, which is why our genital warts and HPV treatment page covers in-clinic removal and clearance separately, but it does reduce the risk of new infections and recurrent disease.
When to see a doctor
HPV vaccination is mostly a routine preventive visit rather than an urgent one, but there are a few situations where the timing matters. If you have had a severe allergic reaction to a previous dose of HPV vaccine or to any of its components (including yeast), the next dose should be deferred and the case reviewed. If you are moderately or severely ill with fever on the day of vaccination, we postpone the dose by a week or two so any reaction can be attributed correctly. Severe immunocompromise (HIV with low CD4 count, active chemotherapy, recent transplant) does not stop vaccination but does change the schedule to three doses, and the timing is best coordinated with your specialist.
Severe rash, swelling of the lips or tongue, difficulty breathing or wheezing after a previous HPV vaccine dose. Fainting that did not recover within a few minutes after a previous shot. High fever above 39 degrees Celsius starting within 24 hours of vaccination. New abnormal vaginal bleeding, persistent pelvic pain or a visible cervical lesion in someone who has never had a Pap smear: these need cervical screening before or alongside vaccination, not after.
You are not sure whether you ever finished an HPV course at home, your vaccination card is missing, you are pregnant or planning pregnancy, you have HIV or another condition affecting immunity, or you have a personal or family history of severe vaccine reactions. A short consultation will sort the schedule, the dose count and the timing. WhatsApp +66 95 073 5550 to book a same-day appointment, or ask about a whole-family booking.
Prevention: vaccination is one layer, not the whole strategy
Gardasil 9 is the single most effective tool we have against HPV-related cancer, but it is not a complete answer on its own. Vaccinated women still need cervical screening on the age-appropriate schedule, because the vaccine covers around 90 percent of cervical cancer-causing types and not 100, and because some women received the older two-valent or four-valent vaccine which covers fewer types. Condoms reduce, but do not eliminate, transmission because HPV lives on skin around the genitals that condoms do not cover. Smoking is an independent risk factor for HPV persistence and cervical cancer, so stopping smoking is part of the prevention conversation. Travellers and expats often combine HPV vaccination with other catch-up shots in the same visit (see travel vaccinations), which is safe and efficient.
Summary
HPV vaccination is one of the few medical interventions that genuinely prevents cancer, and Gardasil 9 covers the types responsible for around 90 percent of HPV-related cancers and genital warts. The earlier the better, ideally age 9 to 14, but catch-up to 26 is routine and shared decision-making to 45 is sensible for many adults. The clinic stocks Gardasil 9, can start the first dose the same day, issues a bilingual vaccination card for school or travel records, and sends WhatsApp reminders for the second and third doses. Vaccination does not replace Pap screening, and our team is happy to organise both in the same visit.
“A lot of the adults we vaccinate tell us they wish they had been offered this at 12. We tell them the same thing every time: it is not too late, the vaccine still works against every type you have not already met, and most people have not met all nine.”

Frequently asked questions
Does the HPV vaccine still work if I am already sexually active or have had HPV before?
Yes, in almost every case. Gardasil 9 covers nine HPV types, and very few people have been exposed to all nine. The vaccine cannot clear an infection you already have, but it protects against every type you have not yet acquired and against re-infection at new body sites such as the anus or throat. Even patients with a past abnormal Pap or a previous warts episode usually benefit, and we offer it routinely in that situation.
I am 35, is it still worth getting vaccinated?
For most adults aged 27 to 45 the answer is yes, especially if you have new or recent partners, are immunocompromised, are a man who has sex with men, or have had a previous abnormal Pap result. The vaccine is licensed up to age 45, and we use shared decision-making to decide on a case-by-case basis. Beyond 45, the formal evidence is thinner, but we still vaccinate selected adults after a conversation.
What are the real side effects of Gardasil 9?
Most people get a sore arm for one to two days, sometimes mild swelling or redness at the injection site, occasionally a low-grade fever or headache. Fainting can happen, particularly in teenagers, which is why we ask everyone to stay seated for 15 minutes afterwards. Severe allergic reaction is very rare. Claims linking the vaccine to infertility, premature ovarian failure, autism or autoimmune disease have been investigated in large studies and not confirmed.
How many doses does my 12-year-old need?
Children aged 9 to 14 need two doses, given six to twelve months apart. That is the full course, and it gives the same protection as three doses in older teenagers because the immune response at this age is exceptionally strong. If the second dose is delayed past 14 it still counts and you do not restart. We issue a bilingual vaccination card suitable for international school records.
Should boys and men get the HPV vaccine?
Yes. HPV causes anal cancer, penile cancer and a large share of oropharyngeal cancers in men, as well as genital warts. Vaccinating men also reduces transmission to future partners. Gardasil 9 is licensed for males from age 9, and the schedule is the same as for females. Men who have sex with men have a particular reason to vaccinate because of higher anal HPV and anal cancer risk.
If I am vaccinated, can I skip cervical screening?
No. Gardasil 9 covers around 90 percent of cervical cancer-causing HPV types, not 100, and earlier vaccines covered fewer. Cervical screening (Pap smear, with or without HPV testing) is still recommended on the age-appropriate schedule for vaccinated women. We run Pap screening at the clinic and can combine it with a vaccination visit if you are due for both.
