The study looked at why some children in urban slums in Myanmar are not getting all their vaccinations. Researchers found that mothers with higher education, permanent residency, and positive views on vaccinations were more likely to have their children fully immunised. The study also showed that having good knowledge about vaccinations and being a first-time mother were linked to higher vaccination rates. This information can help the government and others make better plans to make sure all children in urban slums get the vaccines they need.
