Dr Tarun Sahni, Senior Consultant, Internal Medicine, Indraprastha Apollo Hospitals gives an insight on the importance of vaccines
The ongoing World Immunisation Week is an opportunity to promote vaccination amongst communities and people to ensure their health and protect them against communicable and non-communicable diseases. Widely recognised for its success in saving lives of millions of people world over, nationwide immunisation programmes have helped reach out to even the unreachable communities with cost-effective health interventions.
Vaccination is not just alone meant for children. They are meant to support good health and add value in the life of an adult. Vaccines protect us at every stage of our life. In adult life, one needs to get vaccinated to boost efficacy of the vaccines given in childhood.
World Health Organisation (WHO)’s theme of this year’s campaign is “Protected Together: Vaccines Work”. There are challenges in implementing immunisation programmes, which are due to dogmas and beliefs out of religious sentiments in India. While the Indian government had done well to eradicate these concerns, still a lot of work has to be translated on the ground to ensure that the fruits of immunisation actually benefits people of all generations.
Ensuring vaccination amongst all age groups will help in complete eradication of many diseases and ailments, creating a healthier workforce, which is one of the core elements for any country’s economic growth and financial sustainability. Vaccination also helps in addressing global health concerns, as it prevents transmission of bacteria and viruses across boundaries. Moreover, disease outbreaks impact tourism, trade and economy. Travellers are recommended vaccination hygiene by various health agencies as a precautionary measure. Yellow fever vaccination and photo-booster are mandatory to travellers to some cure on of the world where disease is prevalent and should be complied with completely. Pre-vaccination and countering the disease through immunisation minimises any such impact created.
Recently, a new vaccine called RTS,S developed against malaria, a disease which is responsible for millions of deaths worldwide, has been developed and approved by the WHO. In the initial phase, the vaccine is being administered to patients in Malawi in Africa. Depending on the result, this vaccine will become an integral part of regular vaccination schedule and help in saving millions of lives globally.
Different vaccinations one gets at different stages of life:
- Measles, mumps, rubella (MMR): Two doses of MMR vaccine is administered at the age of 12–15 months and another at 4–6 years.

- Hepatitis B (Hep B): First dose is administered at birth, second at 1-2 months, third when the child is four months old and if suggested by the doctor and the fourth between 6–18 months of age. It is currently recommended for all people, children and adults, in India.
