Insights
Vaccination coverage in children under seven remains suboptimal, with significant gaps in completing immunization schedules. Improving newborn recruitment and follow-up is crucial for enhancing childhood vaccination rates.
Area of Science:
- Pediatrics
- Public Health
- Immunization Programs
Background:
- Childhood vaccination is essential for preventing infectious diseases.
- Assessing vaccination coverage is vital for public health surveillance.
- The Halfway National Health and Nutrition Survey (Ensanut MC 2016) provides valuable data on health trends.
Purpose of the Study:
- To evaluate the vaccination coverage status in children under seven years of age.
- To identify specific vaccination deficits within different age groups.
- To determine factors associated with incomplete immunization schedules.
Main Methods:
- Analysis of data from the Halfway National Health and Nutrition Survey (Ensanut MC 2016).
- Assessment of vaccination coverage rates for various vaccines (BCG, pentavalent, MMR, pneumococcal).
- Statistical analysis to identify variables linked to incomplete vaccination.
Main Results:
- Full vaccination coverage was below 65% for children aged under three years.
- Coverage varied significantly by vaccine, with BCG showing high rates and others lower.
- Incomplete vaccination was associated with younger maternal age and indigenous maternal language.
Conclusions:
- The national vaccination program requires enhancement, particularly in early childhood.
- Strategies to improve newborn enrollment and ensure completion of immunization schedules are needed.
- Leveraging local health service contacts can improve vaccination uptake.
Objective:
To assess vaccination coverage in children under seven years of age.
Materials And Methods:
Study based on the Halfway National Health and Nutrition Survey (Ensanut MC 2016).
Results:
Full vaccination coverage in children <1 year was 51.7%, (range: 67.6% [pentavalent (PV)] to 93.9% [BCG]), in those aged 12-23 months was 53.9% (range: 68.5% [MMR] to 98.3% [BCG]) and in those 24-35 months was 63.2% (range: 85.3% [pneumococcal]) to 98.6% [BCG]). In children aged six years, the coverage of 1 MMR dose was 97.8% and 50.7% for two doses. Only 2.2% of six year olds were not vaccinated. Variables associated with incomplete schedule were age of 2-5 months, mother being under 20 years of age or maternal language indigenous.
Conclusions:
The vaccination program needs to improve recruitment of newborns and their follow-up until they complete their immunization schedule, taking advantage of the local contacts with health services to vaccinate them.

There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
