What are vaccines ? Write the fundamental concept of vaccination and list some of the compulsory vaccines for children.
In short
Vaccines are biological preparations that mimic a mild infection with pathogen antigens, training the immune system to form antibodies and memory cells without causing disease. Compulsory childhood vaccines under the Universal Immunisation Programme, which covers 12 diseases, include BCG, DPT, polio, measles-rubella, hepatitis B and rotavirus.

Universal Immunisation Programme (UIP)
UIP provides free vaccines against 12 diseases, including DPT, polio, measles, rubella, BCG, hepatitis B, and pneumococcal pneumonia, significantly raising immunisation rates in Andhra Pradesh. This program has been instrumental in reducing child mortality and controlling vaccine-preventable diseases nationwide.
HPV Vaccination Drive1
India launched a nationwide free HPV vaccination in 2026 targeting adolescent girls to prevent cervical cancer, confronting gendered mistrust and social resistance through grassroots mobilisation emphasizing rights and trust. This initiative reflects recent advances in expanding vaccine coverage beyond traditional childhood immunisations.
Vaccine Hesitancy and Coverage Gaps
Social resistance and misinformation, especially in rural and tribal areas like Rayalaseema, impede universal coverage; community engagement is essential. Focused efforts are needed to address these gaps through culturally sensitive communication and involvement of local leaders.
Strengthening Infrastructure and Awareness
Enhancing cold chain logistics, training health workers, and targeted communication campaigns in Andhra Pradesh will improve vaccine delivery and acceptance. Strengthening surveillance systems to monitor vaccine safety and disease outbreaks is also critical for sustaining public trust.
