A vaccine usually contains an agent similar to a disease-causing bacteria. When this biological preparation is injected into your body, your immune system recognises and destroys the agent. However, your immune system recognises the agent and next time the actual microbe targets you, it protects you against the disease. Vaccines are usually made from toxins of the microorganism that has been killed or weakened.
Adult Immunizations are Needed
Immunizations are not just for children. Adults need them occasionally, based on factors such as health conditions, travel plans, age, and personal immunisation records. India needs considerable improvement and awareness in the field of adult vaccination. Both the WHO and the Government of India consider childhood vaccination to be a top priority. However, there is no priority on adult immunisation, which is also the most neglected part of health services in India. Vaccines such as pneumococcal and Meningococcal meningitis, hepatitis A and B, rabies, human papillomavirus and tetanus vaccines are the most popular vaccines given in India.
