Gardasil 9 Vaccination for Males
Males should receive routine HPV vaccination at age 11-12 years with a 2-dose schedule (doses at 0 and 6-12 months), which can be started as early as age 9 years. 1, 2
Age-Based Vaccination Schedule
Routine Vaccination (Ages 9-14 Years)
- 2-dose schedule is recommended when vaccination is initiated before the 15th birthday 1, 2
- The 2-dose schedule is based on robust immunogenicity data showing younger adolescents (9-14 years) mount stronger antibody responses than older individuals receiving 3 doses 2
- Longer intervals between doses (closer to 12 months) produce stronger immune responses than shorter intervals 2
Catch-Up Vaccination (Ages 15-21 Years)
- 3-dose schedule is required when vaccination is initiated at age 15 years or older 1, 2
- Vaccination is recommended for males aged 13-21 years who have not been vaccinated previously or have not completed the series 3
Permissive Vaccination (Ages 22-26 Years)
- Males aged 22-26 years may be vaccinated, though this represents individual clinical decision-making rather than routine recommendation 3
- Important caveat: Vaccination at older ages (22-26 years) is less effective in lowering cancer risk due to higher likelihood of prior HPV exposure 3, 1
Special Populations Requiring Extended Vaccination
Men Who Have Sex with Men (MSM)
- Vaccination is recommended through age 26 years for MSM due to higher burden of HPV infection and HPV-related cancers 3, 1
Immunocompromised Individuals
- Vaccination is recommended through age 26 years for immunocompromised persons, including those with HIV infection 3, 1
- 3-dose schedule is required regardless of age at initiation for immunocompromised individuals 2
Clinical Benefits in Males
HPV vaccination in males prevents multiple cancer types and other HPV-related diseases:
- Anal cancer: 89% associated with HPV 1
- Penile cancer: 63% associated with HPV 1
- Oropharyngeal cancer: 72% associated with HPV in males 1
- Genital warts: 90% caused by HPV types 6 and 11 1
In clinical trials, the quadrivalent HPV vaccine demonstrated significant efficacy in males aged 16-26 years, reducing external genital lesions (rate ratio 0.16,95% CI 0.07 to 0.38) and anogenital warts (rate ratio 0.11,95% CI 0.03 to 0.38) compared with control 4
Rationale for Early Vaccination
Vaccination should occur before potential HPV exposure through sexual activity for maximum effectiveness 1, 5
- Nearly 40% of individuals acquire HPV infection within the first 2 years after sexual initiation 1
- Approximately 24% of adolescents report sexual intercourse by 9th grade 2
- The vaccine provides full protection against vaccine-type HPV infections only when given before exposure 5
Practical Administration Considerations
Co-Administration with Other Vaccines
- HPV vaccine can be administered at the same visit as other age-appropriate vaccines (Tdap, MCV4) using separate syringes at different anatomic sites 3, 2
Post-Vaccination Monitoring
- Patients should sit or lie down for 15 minutes after vaccination due to risk of syncope in adolescents 1, 2
Managing Interrupted Schedules
- Do not restart the series if interrupted—continue from where you left off while maintaining minimum intervals 2
- If the first dose was given before age 15, only 2 doses total are needed regardless of when the second dose is actually administered 2
Common Pitfalls to Avoid
- Do not delay vaccination waiting for "optimal" timing—the priority is completing the series before sexual debut 2
- Do not perform pre-vaccination HPV testing—it is not recommended and provides no useful clinical information 1, 5
- Do not assume vaccination eliminates the need for partner screening—vaccinated individuals' partners still require age-appropriate cancer screening per guidelines 5
