Reaching out-of-school girls with HPV vaccination: A qualitative evaluation in six low- and middle-income countries using the RE-AIM framework
This qualitative study across six low- and middle-income countries identifies routine community outreach as the most effective strategy for reaching out-of-school girls with HPV vaccination, while highlighting critical challenges related to data disaggregation, tailored approaches for specific subpopulations, and the cost sustainability of these delivery models.

The Big Picture: The "School Bus" Problem
Imagine the world's fight against cervical cancer is a massive game of catch. The ball is the HPV vaccine, and the goal is to throw it to every single girl who needs it.
For a long time, the easiest way to catch the ball was to wait for the girls to line up at school. This is called a school-based strategy. It's like a school bus picking up kids at a stop; it's efficient, cheap, and catches a huge number of people at once.
But here's the problem: Not every girl is on the bus. Some girls never go to school, some drop out early, or some live in places where schools are hard to find. These are the Out-of-School (OOS) girls. If the health workers only wait at the school gate, these girls never get the ball. They are left behind, and without the vaccine, they are at high risk of getting cervical cancer later in life.
The Study: A Six-Country Road Trip
The authors of this paper went on a "road trip" (via interviews) to six countries (Cambodia, Cameroon, Kenya, Malawi, Mozambique, and Uganda) to ask health workers: "How are you finding the girls who aren't at school?"
They used a checklist called the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance) to organize their findings. Think of this as a mechanic's checklist to see if the car is running well, if it's getting to the right places, and if it can keep running for a long time.
What They Found: The "Door-to-Door" Strategy
The main discovery was that the "school bus" isn't enough. To reach the girls who aren't in school, countries are using Community Outreach.
The Analogy: Instead of waiting for people to come to the clinic (the bus stop), the health workers pack up their vaccines and drive (or walk) into the neighborhoods, markets, and villages. They are essentially doing door-to-door sales, but for health.
1. Where do they go? (Implementation)
Since these girls aren't in school, the health workers had to get creative about where to find them. They set up "pop-up clinics" in places where OOS girls actually hang out:
- Markets: Where girls might be working or selling goods.
- Churches: As one worker noted, "Even if a girl doesn't go to school, she goes to church."
- Border Crossings: To catch families moving in and out of the country.
- Livestock Vaccination Sites: In some nomadic communities, families only show up when their animals are being vaccinated. So, health workers started vaccinating the animals and the girls at the same time.
2. Is it working? (Effectiveness)
The workers feel like it's working because they are seeing more girls get vaccinated. However, there is a blind spot.
- The Missing Scoreboard: The health systems don't have a way to tell the difference between a girl who went to school and a girl who didn't. It's like a store knowing they sold 1,000 apples but not knowing who bought them.
- Because they can't separate the data, they can't be 100% sure if the outreach is actually reaching the right girls or just the ones who were already easy to find.
3. What are the hurdles? (Challenges)
Reaching these girls is hard and expensive.
- The "Trek" Factor: In some places, a nurse might have to walk four miles in the hot sun to vaccinate just three girls. It's physically exhausting and demoralizing.
- The Cost: It costs much more to drive a van to a remote village for three people than it does to vaccinate 300 kids at a school.
- The "Why" Question: Some workers worry: "Is it worth spending so much money on just a few girls?"
- The Answer: The paper argues that yes, it is worth it. If you don't vaccinate these girls now, the cost of treating cervical cancer later will be huge. It's like fixing a small leak in a roof now to prevent the whole house from flooding later.
The Conclusion: A Call for Better Maps and More Fuel
The paper concludes that community outreach is the best tool we have to reach the girls who are missing from school. But to make it better, we need two things:
- Better Maps (Data): We need to start counting specifically how many "out-of-school" girls get vaccinated so we know if our strategies are actually working.
- More Fuel (Resources): We need to fund these outreach trips properly so health workers aren't walking miles in the heat for no reward, and so they can keep doing this vital work.
In short: The "school bus" strategy is great, but it leaves some kids behind. The "door-to-door" strategy is the only way to catch them, but it's a tough, expensive job that requires better tools and more support to keep going.
