Why vaccines matter at your age
Protection from some childhood vaccines fades over time, and some vaccines work best when given in the teen years.
Vaccines train your immune system to recognise germs, so you are protected before you are exposed.
Td (tetanus and diphtheria)
India's Universal Immunisation Programme gives a Td booster at around 10 and 16 years.
Adults usually need Td boosters every ten years, and sometimes after a deep or dirty wound. Ask your doctor whether you are up to date.
HPV vaccine
Human papillomavirus (HPV) is very common and is passed through sexual contact. Some types cause most cervical cancers and also some cancers of the throat, anus and penis, as well as genital warts.
The HPV vaccine works best when given before any exposure, which is why it is offered from age 9. India has been bringing it into its national programme for girls, and it is also available privately.
Older teens and young adults who have not had it can ask a doctor whether it is still recommended for them.
Others to ask about
Depending on your history, a doctor may suggest catching up on hepatitis B, MMR (measles, mumps and rubella), chickenpox or typhoid vaccines, or a yearly flu vaccine.
If you are moving to a hostel, travelling abroad, starting a health-related course or planning a pregnancy, other vaccines may be advised.
Keep your vaccination card or digital record safe. Ask your doctor which vaccines are due for you.
