Knowledge among the rural parents about the vaccinations and vaccination coverage of children in the first year of life in Papua New Guinea - analysis of data provided by Christian Health Services.BackgroundThis analysis aimed to assess rural parents' knowledge about the diseases prevented by vaccinations and establish vaccination coverage in PNG.MethodsKnowledge of vaccinations was checked through a standard questionnaire (five closed questions).We analyzed data on vaccination coverage from 2016 to 2018 from all Catholic health facilities. Analyzed vaccinations were the pentavalent vaccine (DTaP-HiB-HepB) and measles vaccine given in the first year of life. Coverage was calculated based on the number of vaccines used compared to the number of eligible children.Analyzed vaccinations were the pentavalent vaccine (DTaP-HiB-HepB) and measles vaccine given in the first year of life.ResultsFifty-six parents, including 52 mothers and four fathers, participated in the interview. Many parents (46%) understood that the vaccine prevents diseases. During the analyzed period, 25,502 doses of measles vaccine were given, 31,428 children were vaccinated with the pentavalent vaccine. In 2016, the measles vaccine coverage rate was 26.6 and 33.4% for the pentavalent vaccine. In 2017, measles and pentavalent vaccines' coverage rate was 12.5 and 16.6%, respectively. There were significant differences in immunization coverage between provinces. A decreasing trend in the number of administered vaccinations was observed.ConclusionThe results of this analysis demonstrate that in PNG, the majority of children are not fully immunized.There are significant differences in the vaccination coverage between provinces. As protection from diseases is low, there is a very high risk of an outbreak of the vaccine-preventable disease in the community.Delivery of vaccinations in PNG encounters many barriers, from access to healthcare services to natural disasters and inter-tribial conflicts.
