The HPV vaccine is not mandatory in most of the United States. Only a handful of jurisdictions, including Virginia, Rhode Island, Hawaii, and Washington, D.C., require it for school entry. In every other state, the vaccine is recommended by the CDC but entirely optional.
Even in the states that do require it, parents can opt out. This makes the HPV vaccine one of the easiest school-required vaccinations to decline, which is worth understanding whether you’re a parent navigating school forms or simply trying to figure out where you stand.
Which States Require the HPV Vaccine
Virginia was the first state to mandate the HPV vaccine, and the requirement currently applies before a child enters 7th grade. A complete series of two doses is required under Virginia law, with the first dose administered before the start of that school year. However, Virginia’s law includes a notable provision: after reviewing educational materials approved by the state Board of Health, a parent can simply choose not to vaccinate their child. No medical reason or religious belief is necessary. The parent’s sole discretion is enough.
Rhode Island phases in its requirement across middle and high school. Students entering 7th grade need at least one dose, with additional doses required in 8th and 9th grade to complete the full series. Hawaii and Washington, D.C., also have school-entry requirements on the books.
No other states currently mandate the HPV vaccine for school attendance. Several states have introduced bills over the years proposing mandates or funding for HPV vaccination programs, but most of those efforts either stalled in committee or resulted in education and awareness campaigns rather than binding requirements.
How Exemptions Work
Every state with a school vaccination requirement of any kind offers medical exemptions, meaning a doctor can certify that a particular vaccine isn’t appropriate for a specific child. Beyond that, the landscape varies. Many states also allow religious exemptions, and a smaller number permit philosophical exemptions based on personal or moral beliefs rather than any specific religious doctrine.
For the HPV vaccine specifically, exemptions tend to be even more accessible than for other school-required vaccines like measles or tetanus. Virginia’s opt-out, for example, doesn’t even require paperwork beyond the parent’s decision. This is a significant departure from how most school vaccine mandates work, where families typically need to submit a signed form or obtain a doctor’s note. The practical result is that even in states with HPV mandates, compliance is essentially voluntary.
What the CDC Recommends
Federal health authorities recommend the HPV vaccine for all preteens at age 11 or 12, though the series can start as early as age 9. The number of doses depends on when you start. Children who get their first dose between ages 9 and 14 need two shots, spaced 6 to 12 months apart. Anyone who starts the series at age 15 or older needs three doses, as does anyone with a weakened immune system.
The vaccine is approved for people up to age 45, though the greatest benefit comes from vaccination before any exposure to HPV. That’s the reasoning behind the preteen recommendation: the vaccine works best when given well before a person becomes sexually active. HPV causes nearly all cases of cervical cancer along with several other cancers affecting the throat, mouth, and genital area in both men and women.
Why So Few States Mandate It
The HPV vaccine has faced more political resistance than most childhood vaccines. Because HPV is sexually transmitted, mandates have drawn opposition from parents and advocacy groups who view them as overreach into family decisions about sexual health. This political dynamic has kept most state legislatures from passing requirements, even as the medical case for the vaccine has strengthened over the years.
Research on the handful of states that have passed HPV-related legislation (including funding programs and awareness campaigns, not just mandates) shows limited evidence that these laws meaningfully increased vaccination rates on their own. A study examining state-level data from 2009 through 2017 found no statistically significant jumps in HPV vaccination after legislation passed. Vaccination rates did trend upward over that period, but the increases weren’t clearly tied to the laws themselves. The implication is that broader public health messaging, provider recommendations, and insurance coverage have likely done more to drive uptake than mandates have.
What This Means for Your Family
If you live outside Virginia, Rhode Island, Hawaii, or D.C., no law requires your child to get the HPV vaccine. If you live in one of those jurisdictions, you can still decline it. The process for opting out ranges from a simple parental decision (Virginia) to filing a standard exemption form.
The vaccine is covered without cost under most insurance plans and through the federal Vaccines for Children program for uninsured kids. If your child is approaching middle school, your pediatrician will likely bring it up at a routine visit. Two doses given a year apart before age 15 completes the series for most children.
