[Epidemiological investigations on measles in unvaccinated and vaccinated children (author's transl)]
Insights
The combination of split and live measles vaccines offers the highest protection rate (0.94) against measles complications. This combined approach significantly reduces measles complications compared to single vaccine types or no vaccination.
Area of Science:
- Pediatrics
- Immunology
- Public Health
Context:
- Measles remains a significant public health concern globally.
- Vaccination strategies are crucial for controlling measles outbreaks.
- Evaluating the effectiveness of different measles vaccine schedules is essential.
Purpose:
- To assess the protection rates and complication incidence of various measles vaccination strategies in children.
- To compare the efficacy of live attenuated vaccine, split vaccine, and a combined vaccine regimen.
- To determine the impact of vaccination on measles-related complications.
Summary:
- A national study involving 82 pediatricians evaluated 9472 children over 3.13–5.46 years.
- Protection rates: live vaccine (0.89), split vaccine (3 doses, 0.67), combined (split 3 doses + live later, 0.94).
- Measles complications: unvaccinated (5.9%), live vaccine failure (2.9%), split vaccine failure (2.8%), combined vaccine (0%).
Impact:
- The combined measles vaccine regimen demonstrates superior efficacy in preventing complications.
- Findings support optimized vaccination schedules for enhanced measles control.
- This research informs public health policy on measles prevention strategies.
Abstract:
A national study, with participation of 82 paediatricians, was carried out on 9472 children over medium observation periods of between 3.13 and 5.46 years with evaluation of the history of measles, incidence of complications and details of vaccination procedure performed. The protection rate of primary vaccination with live vaccine was 0.89, with split vaccine (3 times) 0.67 and after a combination of split vaccine (3 times) with live vaccine (9 to 12 months later) 0.94. Complications due to measles in unvaccinated children were found in 5.9% of cases. Measles complications after failure of vaccination were found in 2.9% and 2.8% of children vaccinated with live or split vaccine, respectively. No such complications were observed in children vaccinated with a combination of split and live vaccines.
