In an age where access to information has never been better, it is troubling to see enduring misconceptions and myths about vaccines, particularly among parents. The decision, and the timing, to vaccinate children is increasingly influenced by misinformation, resulting in hesitancy and delayed vaccination timetables. However, the repercussions of these delays can be significant, affecting not just the well-being of individual children but also the wider community.
Dr Nishant Bansal, Consultant -Pediatrician & Neonatologist, Motherhood Hospitals, Noida, debunks common vaccine myths and emphasises the critical importance of timely vaccination for children.
Myth: Vaccines are unnecessary because diseases have been eradicated
Fact: While some diseases have been significantly reduced due to vaccination efforts, they have not been entirely eradicated. Diseases like measles and pertussis (whooping cough) still pose significant threats, especially to unvaccinated individuals. Failure to vaccinate can lead to outbreaks, as seen in recent years in various parts of the world.
Myth: Vaccines contain harmful ingredients that can cause health problems
Fact: Vaccines undergo rigorous testing for safety and efficacy before being approved for public use. The ingredients in vaccines are carefully selected and present in very small quantities. Common ingredients like thimerosal and aluminum are used in trace amounts and have not been shown to cause harm at the levels found in vaccines.
Myth: Vaccines can overload a child's immune system
Fact: The human immune system is equipped to handle exposure to numerous antigens daily. Vaccines contain only a tiny fraction of the antigens that children encounter naturally in their environment. Research has consistently shown that the recommended vaccine schedule is safe and does not overwhelm the immune system.
Myth: Natural immunity is better than vaccine-induced immunity
Fact: While natural immunity from contracting a disease may provide protection, it often comes at a significant cost. Many vaccine-preventable diseases can lead to severe complications, hospitalisation, and even death. Vaccination offers a safer way to develop immunity without risking the serious consequences of the disease.
Myth: Vaccines can cause autism
Fact: This myth originated from a now-discredited study and has been debunked by extensive scientific research. Multiple studies involving millions of children have found no link between vaccines and autism. The overwhelming consensus among medical experts is that vaccines are not associated with autism.
Why is it crucial to adhere to the recommended vaccine schedule?
Timely vaccination plays a crucial role in cutting hospital stays and preventing the spread of infectious diseases. Vaccines work most effectively when administered according to the recommended schedule, providing children with optimal protection from vaccine-preventable diseases, says Bansal.
Delaying or skipping vaccines not only leaves children vulnerable to potentially life-threatening illnesses but also undermines herd immunity, putting the entire community at risk. Herd immunity occurs when a significant portion of the population is immune to a disease, making it difficult for the disease to spread. By vaccinating children on time, we contribute to the collective effort to protect those who cannot be vaccinated, such as infants and individuals with compromised immune systems.
