Polio Eradication Timeline of India: Endemic Disease → EPI → Universal Immunization → Pulse Polio → Polio-Free → Certified

For decades polio left thousands of Indian children every year with weak or paralysed legs, and calipers and crutches were a common sight. India began routine vaccination in 1978, spread it to every district from 1985, and in 1995 launched Pulse Polio — two drops for every child under five on a single day. After years of house-to-house visits, transit teams, and huge setbacks, India recorded its last case in January 2011 and was certified polio-free in 2014.

This timeline covers the Salk and Sabin vaccines, the Expanded Programme on Immunization, the Universal Immunization Programme, the cold chain, Pulse Polio and “Do Boond Zindagi Ki”, polio surveillance, finger and house marking, transit and mobile teams, the 2002 and 2009 outbreaks, the last case in Howrah, WHO certification, IPV, the 2016 vaccine switch, and how India stays polio-free.

Why the Story of Polio Eradication Matters

Many experts once believed India would be the last place on Earth to get rid of polio, because of its huge population, crowded cities, poor sanitation, and constant migration. Its success showed that a well-organised public health campaign — millions of health workers, volunteers, scientists, and parents working together — can defeat a disease even in the hardest conditions, and the same network now helps with other vaccines.

Big picture

India’s fight against polio in one view

Polio was endemic across India until the 1970s. Routine vaccination began with EPI in 1978, the Universal Immunization Programme reached every district by about 1990, Pulse Polio campaigns from 1995 vaccinated every child under five again and again, and the last wild polio case was recorded in 2011, leading to WHO certification in 2014.

Polio in India Then vs Now at a Glance

🦽 EndemicBefore 1978

Polio Everywhere: Calipers & Crutches

Before routine vaccination, the poliovirus spread freely through contaminated water and hands in crowded towns and villages. Most infected children had only a mild fever, but some woke up unable to move a leg, and families turned to hospitals, physiotherapy, calipers, and crutches. Vaccines existed abroad but reached very few Indian children.

  • 1908–1955: Scientists identify the poliovirus (1908), and the injected inactivated polio vaccine (IPV) developed by Jonas Salk is licensed in the United States in 1955.
  • Early 1960s: Albert Sabin’s oral polio vaccine (OPV) — cheap drops that need no needle and also protect the gut — comes into use and is soon tried in a few Indian cities.
  • 1960s–1970s: Polio is common in every Indian state, and hospitals and rehabilitation centres treat children with paralysed legs using physiotherapy, calipers, crutches, and surgery.
  • 1974: The World Health Assembly launches the global Expanded Programme on Immunization (EPI) to protect children against six diseases, including polio.

Technology

  • Salk vaccine: Injected, killed virus.
  • Sabin vaccine: Oral drops, weakened virus.
  • Calipers: Metal leg supports.

Features

  • No routine vaccination: Few children protected.
  • Monsoon outbreaks: Cases rise in wet months.
  • Lifelong disability: No cure for paralysis.
💉 EPI1978 – 1984

Expanded Programme on Immunization

In 1978 India started its first national programme of routine childhood vaccination. Health centres began offering a set of free vaccines, including oral polio drops, but coverage stayed low, especially in villages, because vaccines lost their strength without proper refrigeration and many parents had never heard of them.

  • 1978: India launches the Expanded Programme on Immunization (EPI), offering BCG, DPT, oral polio vaccine, and typhoid vaccine to infants and young children, mainly through hospitals and health centres.
  • Late 1970s–early 1980s: Coverage stays low in rural areas, and many doses lose their strength because the vaccine must be kept cold from the factory to the child.
  • 1983: India’s first National Health Policy sets goals for universal immunisation of children.
  • Early 1980s: Surveys of lameness in schools and villages show that polio is still paralysing a very large number of Indian children every year.

  • Refrigerators: Only at bigger centres.
  • Paper cards: Dose records.

Features

  • Fixed clinics: Parents had to travel.
  • Free vaccines: A basic set.

🏥 UIP1985 – 1994

Universal Immunization Programme

The Universal Immunization Programme aimed to vaccinate every infant and pregnant woman in every district. It added the measles vaccine, trained health workers to hold regular immunisation sessions, and built a national cold chain of ice-lined refrigerators and deep freezers, while the world set itself the goal of wiping out polio.

💧 Pulse Polio1995 – 2004

Pulse Polio: Do Boond Zindagi Ki

Routine vaccination alone could not stop polio, so India began national immunisation days. On a single Sunday, lakhs of booths gave two drops of oral polio vaccine to every young child, even those already vaccinated, and teams later went house to house to find children who were missed. A national surveillance network checked every case of sudden weakness.

  • 9 December 1995: The first Pulse Polio round gives oral polio drops to about 8.7 crore children under three on a single day, with a second round in January 1996; later rounds cover all children under five.
  • 1997: The National Polio Surveillance Project, run with WHO, starts reporting every case of acute flaccid paralysis (sudden floppy weakness) in children and testing stool samples in a network of laboratories.
  • 1999: Vaccinators begin visiting every house after booth day, and the world’s last case of wild poliovirus type 2 is found in Aligarh, Uttar Pradesh.
  • 2002: A large outbreak of about 1,600 cases, mostly in Uttar Pradesh and Bihar, shows the virus surviving among crowded, poor communities with weak immunity.

🚆 Last Mile2005 – 2011

The Last Mile: Transit Teams to the Last Case

The virus held on in western Uttar Pradesh and central Bihar, where crowding, floods, diarrhoea, and poor sanitation weakened the vaccine’s effect. India answered with stronger vaccines, more frequent rounds, teams at railway stations and bus stands, mobile teams for migrant families, and community leaders who won the trust of doubtful parents.
