EPI Launch: The World Health Organization (WHO) started the "Expanded Program on Immunization" to protect children from six major diseases: diphtheria, pertussis (whooping cough), tetanus, poliomyelitis (polio), tuberculosis, and measles. Support: UNICEF has continuously supported this program. Key Points: "Expanded" Meaning: Adding more vaccines and ensuring the program reaches all parts of the country, especially underserved areas. Alma-Ata Conference (1978): Highlighted immunization as vital to achieving health for everyone by 2000. Milestones: 1978: India began the Expanded Program on Immunization (EPI), mainly in urban areas. 1983: Introduced Tetanus Toxoid (TT) immunization for pregnant women. 1985: EPI was renamed the "Universal Immunization Program" (UIP) by UNICEF, aiming to reduce deaths and illnesses from six vaccine-preventable diseases. Indigenous Vaccine Production: Increased to meet the program's needs. Cold Chain System: Set up to ensure vaccines stay effective. 1989-90: All districts in India were covered. 1986: Technology mission on immunization started, monitored under the Prime Minister's 20-point program. 1992: Child Survival and Safe Motherhood (CSSM) program began, including UIP and safe motherhood initiatives. 1995: Pulse Polio Immunization Program started, targeting children under five with additional polio doses during December and January. 2005: National Rural Health Mission (NRHM) launched. 2010-11: Hepatitis B vaccine added, given at 6, 10, and 14 weeks with DPT and OPV. 2006: Japanese Encephalitis vaccine introduced in high-risk areas. 2011: India introduced the pentavalent vaccine (DPT, Hepatitis B, Hib) in Kerala and Tamil Nadu. 2013: Multi-dose vial policy and two doses of Japanese Encephalitis vaccine in endemic areas introduced. 2014: Mission Indradhanush launched to vaccinate all children under five by 2020, with support from WHO, UNICEF, and Rotary International. 2015: Inactivated Polio Vaccine (IPV) introduced in six states, expanded nationwide in 2016. 2016: Rotavirus vaccine introduced in four states. Components of Universal Child Immunization (UCI) Overview: Two Main Components: Immunization of Pregnant Women: Protects against tetanus with two doses of tetanus toxoid (TT) or a booster dose. Immunization of Children: Targets diseases like diphtheria, pertussis (whooping cough), tetanus (DPT), polio (OPV), tuberculosis (BCG), and measles within the first year of life. Goals: Pregnant Women: Achieve 100% coverage with two TT doses or a booster. Children: Reach 85% coverage with three doses of DPT, OPV, one dose of BCG, and one dose of measles by 1990. Implementation: Initial Phase (1985): Began in 30 selected districts and 50 medical college catchment areas. Current Phase: Expanded to all districts and medical colleges, integrated with Maternal and Child Health (MCH) services, without additional staffing. Program Implementation Plan (PIP) to Strengthen Routine Immunization Key Strategies: Vaccine Delivery: Ensures smooth transportation of vaccines from Primary Health Centers (PHC) to sub-centers and outreach areas. Retired Manpower: Utilized in underserved slum areas to support immunization efforts. Mobility Support: Provided to district immunization officers for better supervision. Review Meetings: Held at the state level to monitor district progress. Community Mobilization: Assisted by ASHA workers, women's self-help groups, and others to bring children to immunization clinics. Materials Support: Includes printing immunization cards, monitoring sheets, etc. Central Government Assistance: Auto-disposable syringes. Downsizing BCG ampoules from 20 to 10 doses. Cold chain maintenance to ensure vaccine potency. Immunization Schedule 2020 Mandatory Vaccines: Administered to all children in India under the Universal Immunization Program (UIP) as per the latest guidelines by the Government of India and the Indian Academy of Pediatrics (IAP), following WHO recommendations. Schedule Overview: Weeks (W), Months (M), and Years (Y): The schedule specifies when each vaccine should be given, tailored to the child’s age and health history.
