Vaccinations are one of the most effective ways to protect people from serious infectious diseases. In India, vaccines are given to children from birth and are also recommended for adults in certain situations, such as during pregnancy, for travel, or for people with specific health conditions. Understanding how vaccines work, and why schedules matter, can help families make informed decisions.

How Vaccines Work
Vaccines work by teaching the immune system to recognise a germ, such as a virus or bacterium, without causing the full disease. When the body later encounters the real germ, it can respond more quickly and effectively. This reduces the chance of getting seriously ill and, for many diseases, reduces the spread of infection in the community.
Vaccines for Children
In India, the national immunisation programme covers vaccines against diseases such as tuberculosis, polio, diphtheria, tetanus, whooping cough, hepatitis B, measles, rubella, and others, with additional vaccines recommended at different ages. Children usually receive vaccines at birth, at six, ten, and fourteen weeks, and at later milestones through early childhood and adolescence.
Keeping a vaccination card or record is very helpful. It shows which vaccines have been given, when the next dose is due, and helps avoid duplication or missed doses when a child changes doctors or schools.
Vaccines for Adults
Vaccination is not only for children. Adults may need vaccines for several reasons, including:
- Booster doses, such as tetanus boosters, after injuries or at recommended intervals
- Vaccines during pregnancy, as advised by a doctor, to protect both mother and baby
- Vaccines for people with chronic conditions, such as diabetes, heart disease, or weakened immunity, who may be at higher risk from infections
- Vaccines for travel to areas where certain diseases are more common
- Seasonal vaccines, such as influenza vaccines, for older adults and high-risk groups
Adults often forget their vaccination history, so it is worth checking with a doctor, especially before pregnancy, travel, or major surgery. A doctor can review records and recommend only the vaccines that are appropriate for that person.
Safety, Side Effects, and Common Concerns
Vaccines are tested for safety before use, and side effects are usually mild and short-lived, such as soreness at the injection site, mild fever, or tiredness for a day or two. Serious side effects are rare. If a child or adult develops a high fever, unusual swelling, difficulty breathing, or other worrying symptoms after vaccination, medical help should be sought promptly.
Some people worry that vaccines overwhelm the immune system, but the immune system encounters many germs every day, and vaccines are designed to work safely within that system. Doctors and health workers can answer questions and explain the benefits and risks for each vaccine, so families do not have to rely on rumours or social media posts.
Vaccination also protects the wider community. When enough people are immunised, diseases spread less easily, which helps protect babies too young to be vaccinated and people who cannot receive certain vaccines for medical reasons.
Keeping vaccinations up to date is a simple, powerful step for family health. By following the recommended schedule, keeping records, and asking a doctor about any doubts, families in India can protect children and adults from many preventable diseases.
