New Delhi: Timely vaccination in childhood is one of the most significant public health achievements, offering protection against a range of serious, potentially
fatal diseases. It is important to highlight how staying up to date with recommended vaccines safeguards not only individual children but entire communities. In an interaction with News9Live, Dr. Sandeep R, Consultant – Neonatology and Paediatrics, Rainbow Children’s Hospital, Marathahalli, spoke about the importance of regular and timely vaccinations for children.
Vaccines work by stimulating the immune system to recognise and fight pathogens before they can cause disease. When administered according to the recommended schedule, they provide the best possible protection at ages when children are most vulnerable to infections such as measles, polio, diphtheria, whooping cough, and other vaccine-preventable illnesses. Following this schedule helps ensure that a child’s immune response is strong, sustained, and timely, significantly reducing the risk of severe complications or hospitalisation.
Missing or delaying vaccines creates gaps in protection. A delayed immunisation means that a child remains susceptible to infection for longer than necessary, increasing the risk of contracting diseases that are preventable with on-time vaccination. These diseases can result in significant harm, including long-term disability or death, especially in young children whose immune systems have not fully matured. Furthermore, incomplete vaccination can undermine broader disease-control efforts, making outbreaks more likely in communities where coverage is low.
Beyond individual protection, childhood vaccines contribute to herd immunity, a collective shield that reduces disease spread and protects those who cannot be vaccinated due to medical conditions or age. High immunisation coverage prevents the circulation of pathogens in the population and limits outbreaks. When parents adhere to the complete vaccination schedule, they not only secure their own child’s health but also strengthen community protection against preventable illness.
It is also essential to address vaccine hesitancy, which can stem from misinformation, fear of side effects, or misconceptions about disease risk. Public health communication grounded in scientific evidence helps parents understand that vaccines are thoroughly tested for safety and effectiveness, and that the benefits of immunisation far outweigh the risks. Awareness and education about timely immunisation promote confidence in vaccines and encourage adherence to immunisation schedules.
Sustained awareness and education are key to improving vaccination uptake. Clear communication about the benefits of timely immunisation, reminders about vaccination schedules, and community-level awareness initiatives help reinforce the importance of completing all recommended doses.
The message is clear: timely childhood vaccination is not optional. It is a critical responsibility. Ensuring that children receive vaccines on schedule protects individual health, strengthens community immunity, and helps secure a healthier future where preventable diseases no longer pose a threat to young lives.
