Every year on 16th March, India observes National Vaccination Day, also known as National Immunisation Day, to raise awareness about the critical importance of vaccines in protecting public health. The date holds deep historical significance, marking the anniversary of the launch of India’s Pulse Polio Programme in 1995, a milestone that set the country on a path to one of the greatest public health victories in human history

The Historical Significance: 16th March 1995
On this day in 1995, India administered the first doses of oral polio vaccine (OPV) under its nationwide Pulse Polio Immunisation Programme. At the time, polio was endemic across India, crippling thousands of children every year. The campaign’s ambition was extraordinary, to vaccinate every child under five years of age simultaneously across the entire country, leaving the poliovirus no place to hide.
The effort was monumental. Millions of health workers, volunteers, and government officials fanned out across cities, villages, deserts, and forests. Vaccination booths were set up at railway stations, bus stands, and remote tribal settlements. The campaign reached children who had never before had access to any form of healthcare.
After 16 years of sustained effort, on 13th January 2011, India reported its last case of wild poliovirus. On 27th March 2014, the World Health Organisation (WHO) officially certified India as polio-free, a triumph celebrated around the world, especially remarkable given India’s population of over a billion people and its vast geographic and logistical challenges.
National Vaccination Day commemorates this achievement and renews India’s commitment to immunisation every year.
Why Vaccination Matters
Vaccines are among the most powerful and cost-effective tools in public health. They work by training the immune system to recognise and fight specific pathogens, viruses or bacteria, without causing the disease itself. When enough people in a community are vaccinated, the spread of disease slows or stops entirely, a phenomenon known as herd immunity or community protection. This is especially vital for protecting those who cannot be vaccinated, new borns, the elderly, and people with certain medical conditions.
Globally, vaccines prevent an estimated 2 to 3 million deaths every year. In India, the impact has been transformative, dramatically reducing the burden of diseases that once killed or disabled hundreds of thousands of children annually.
India’s Universal Immunisation Programme (UIP)India’s Universal Immunisation Programme (UIP), launched in 1985, is one of the largest public health programmes in the world. It provides free vaccines to children and pregnant women against twelve vaccine-preventable diseases. Delivered through a network of government health centres, Anganwadi centres, and mobile vaccination units, the UIP aims to reach every child in India, from urban apartments to the most remote forest villages.
The programme has made measurable progress: smallpox was eradicated, polio was eliminated, and deaths from measles, tetanus, and diphtheria have fallen sharply over the decades.
The COVID-19 Vaccination Drive: A Historic Achievement
India’s vaccination story reached a new chapter with the COVID-19 pandemic. Launched on 16th January 2021, India’s COVID-19 vaccination programme, called Co-WIN — became the largest vaccination drive in history. Using indigenously developed vaccines including Covaxin (developed by Bharat Biotech) and Covishield (manufactured by the Serum Institute of India), the programme administered over 2.2 billion doses, protecting hundreds of millions of people.
The Co-WIN digital platform, which allowed citizens to register, book appointments, and download vaccine certificates, was praised globally as a model for large-scale vaccine delivery. India also supplied vaccines to dozens of other countries under the Vaccine Maitri (Vaccine Friendship) initiative, reinforcing its role as the world’s pharmacy.
How National Vaccination Day is Observed
On 16th March each year, the Government of India, state health departments, NGOs, schools, and community organisations come together to observe the day with:
Awareness campaigns: Radio broadcasts, television spots, social media drives, and public rallies educate families about the importance of completing their children’s vaccination schedules.
Vaccination camps: Special immunisation drives are organised in underserved areas, bringing healthcare workers directly to communities that may otherwise be difficult to reach.
School programmes: Students participate in essay writing, drawing competitions, and pledge-taking ceremonies emphasising the importance of preventive healthcare.
Recognition of health workers: Frontline workers, especially ASHAs (Accredited Social Health Activists) and ANMs (Auxiliary Nurse Midwives), who are the backbone of India’s immunisation delivery, are honoured for their tireless work.
Theme-based messaging: A year carries a theme to focus public attention on a specific goal, such as reaching zero-dose children or strengthening cold-chain infrastructure.
Challenges That Remain
Despite remarkable progress, India still faces significant challenges in achieving full immunisation coverage:
Zero-dose children: Millions of children, particularly in Bihar, Uttar Pradesh, Rajasthan, and Madhya Pradesh, still receive no vaccines at all. These children are concentrated in areas with poor infrastructure, low health literacy, and hard-to-reach geographies.
Vaccine hesitancy: Misinformation, religious beliefs, and mistrust of the healthcare system continue to prevent some families from vaccinating their children.
Cold-chain infrastructure: Vaccines must be stored and transported at specific temperatures. Maintaining this cold chain across India’s vast and varied terrain, from the high Himalayas to the Thar Desert, remains a logistical challenge.
Urban slums and migrant populations: Mobile and marginalised communities often fall through the gaps of routine immunisation programmes and are disproportionately vulnerable to outbreaks.
Addressing these challenges requires not just healthcare delivery but sustained community engagement, education, and investment in infrastructure.
India’s Global Role in Vaccination
India is home to the Serum Institute of India in Pune, the world’s largest vaccine manufacturer by volume. It produces over 1.5 billion doses of various vaccines every year, supplying immunisation programmes in over 170 countries. India’s vaccine industry is central to GAVI (the Global Alliance for Vaccines and Immunisation) and COVAX, the global vaccine equity initiative.
The country’s combination of manufacturing capacity, scientific expertise, and cost-effective production makes it an indispensable partner in global health security.
The Broader Vision: Mission Indradhanush
Launched in 2014, Mission Indradhanush (named after the seven colours of the rainbow, representing the seven vaccines initially covered) aimed to accelerate immunisation coverage in districts with the lowest vaccination rates. It has since expanded its scope and continues to target the most underserved communities. Under Intensified Mission Indradhanush (IMI), India has made significant strides in covering children who had missed routine vaccinations.
Why This Day Matters
National Vaccination Day is a reminder that public health is a collective responsibility. Every child vaccinated is not only a child protected, it is a link broken in the chain of transmission that could otherwise carry disease to the most vulnerable. It honours the scientists who developed lifesaving vaccines, the health workers who walked kilometres to deliver them, the parents who trusted the process, and the policymakers who made immunisation a national priority.
India’s polio-free status was not an accident. It was the result of political will, scientific rigour, community mobilisation, and decades of relentless effort. National Vaccination Day exists to ensure that spirit never fades, and that every child in India, no matter where they are born, has the chance to grow up healthy and protected.
“Vaccines are a gift from science to humanity. National Vaccination Day is India’s promise to make sure that gift reaches every child.”
