As India advances in childhood immunization, experts urge parents and healthcare providers not to overlook a critical window in child’s vaccine schedule, the booster dose of Diphtheria, Tetanus, Pertussis & Polio at school entry age.
While primary vaccination during infancy provides early protection, scientific evidence shows that immunity to diphtheria, tetanus, pertussis, and polio diminishes over time. If children don’t get timely booster shots, they could be at risk of serious diseases, especially when they start going to school and interacting with more people.
The Indian National Immunization Program (NIP) recommends a DTP vaccination at 6, 10, and 14 weeks of age, followed by a booster at 16–24 months, and 2 fractional doses of polio at 6 and 14 weeks of age. However, by the time a child reaches 4–6 years of age, protective antibody levels decline, making them susceptible to infection and potential outbreaks.
“By the time children reach school-going age, their exposure to infections increases rapidly while the protection from earlier vaccines begins to wear off,” says Dr. Nirav Benani, Urva Children Hospital, Twinkle Complex, Anand Nagar Road Satellite, Ahmedabad. “Booster doses at this stage are a crucial part of the immunisation journey, ensuring that children remain protected as they step into larger group environments.”
The IAP recommends the use of modern combination vaccines, which offer protection against multiple infections with a single dose.⁷ These are especially beneficial during school years, where the risk of transmission is higher, and are essential in upholding major public health achievements such as India’s polio-free certification.⁸
“Schools are an ideal setting to reinforce both learning and health,” adds Dr. Nirav Benani. “Asking for updated vaccination records isn’t just good practice, it’s a preventive measure that helps reduce illness-related absences and supports uninterrupted development during the early years of education.”
As more people learn about the importance of vaccines, many schools are helping by asking for updated health and vaccination records. Vaccination isn’t just a one-time task—it’s something we need to keep up with to stay healthy. Make sure your child is fully protected before starting school. It’s one of the best ways to keep them safe and build a healthier future for everyone.
