Insights
Parental empathy for children receiving shots led to delayed measles vaccination, indicating poor adherence to recommended schedules in São Paulo. Understanding perceptions is key to improving vaccination rates.
Area of Science:
- Public Health
- Epidemiology
- Vaccinology
Background:
- Vaccination campaign success hinges on adherence to immunization schedules.
- Understanding factors influencing timely measles vaccination is crucial for public health.
Purpose of the Study:
- To investigate risk factors for delayed measles vaccination in children.
- To explore caregiver perceptions regarding measles vaccination in São Paulo, Brazil.
Main Methods:
- A case-control and exploratory study was conducted in metropolitan São Paulo.
- Interviews with caregivers of 122 children assessed perceptions of measles vaccination and the disease.
Main Results:
- Demographic factors like age, region, marital status, and education were not associated with adequate measles vaccination.
- Caregiver empathy towards children receiving injections was linked to vaccination delays.
- Most children received measles vaccinations outside the recommended age windows.
Conclusions:
- There is significant non-compliance with the recommended measles vaccination schedule in São Paulo.
- Parental feelings of pity for children undergoing vaccination can be a barrier to timely immunization.
Context And Objective:
The success of vaccination campaigns depends on the degree of adherence to immunization initiatives and schedules. Risk factors associated with children's failure to receive the measles vaccine at the correct age were studied in the city of São Paulo, Brazil.
Design And Setting:
Case-control and exploratory study, in the metropolitan area of São Paulo.
Methods:
The caregivers of 122 children were interviewed regarding their perceptions and understanding about the measles vaccination and the disease.
Results:
The results showed that age, region of residence, marital status and education level were unrelated to taking measles vaccines adequately. Most individuals remembered being informed about the last annual vaccination campaign by television, but no communication channel was significantly associated with vaccination status. The answers to questions about knowledge of the disease or the vaccine, when analyzed alone, were not associated with taking measles vaccinations at the time indicated by health agencies. The results showed that, when parents felt sorry for their children who were going to receive shots, they delayed the vaccination. Most of the children did not take the measles vaccination on the exactly recommended date, but delayed or anticipated the shots.
Conclusion:
It is clear that there is no compliance with the government's recommended measles vaccination schedule (i.e. first dose at nine and second at 15 months of age, as recommended in 1999 and 2000). Feeling sorry for the children receiving shots can delay vaccination taking.
