Pakistan’s immunisation drive saves millions, reshapes child health landscape: WHO

Pakistan’s sustained immunisation efforts have protected millions of lives over nearly five decades, preventing an estimated 2.6 million child deaths, according to the World Health Organization.

As World Immunization Week approaches, the global health body highlighted the country’s progress since the launch of its Expanded Programme on Immunisation (EPI) in 1978. Developed in partnership with international organisations, the initiative has reached more than 160 million children and 130 million mothers with essential vaccines.

The programme’s origins date back to Pakistan’s successful eradication of smallpox in 1976, a milestone that paved the way for broader immunisation campaigns. Since then, vaccines have played a central role in reducing deaths caused by preventable diseases and improving overall child survival.

Sharp decline in polio and tetanus cases

According to the WHO, Pakistan has made significant gains against polio, with paralytic cases dropping by nearly 99.8 per cent since 1994. This progress reflects years of sustained vaccination drives and community outreach, despite persistent challenges.

The country has also achieved elimination of maternal and neonatal tetanus in several regions, including Punjab, Sindh, Islamabad, Gilgit-Baltistan, and Pakistan-administered Kashmir. As a result, around 80 per cent of the population now lives in areas where neonatal tetanus is no longer considered a major public health threat.

Health experts say these achievements underscore the impact of long-term investment in routine immunisation systems, particularly in reaching vulnerable populations.

Vaccination remains most effective public health tool

The WHO estimates that immunisation prevents up to 17 per cent of all childhood deaths in Pakistan, making it one of the most cost-effective health interventions available.

Dr Luo Dapeng praised the efforts of frontline health workers, scientists, and public health authorities who have contributed to the country’s progress. He emphasised that vaccines are grounded in strong scientific evidence and remain essential in protecting children from life-threatening illnesses.

The immunisation effort is supported by a vast workforce, including more than 15,000 routine vaccinators and over 400,000 personnel involved in polio campaigns. Their work ensures that vaccination services reach communities across the country, regardless of geography or socio-economic barriers.

Beyond survival: improving quality of life

In addition to reducing mortality, immunisation programmes have prevented tens of millions of cases of illness, disability, and hospitalisation over the years. Diseases such as measles, pneumonia, polio, and diarrhoeal infections, once major contributors to child mortality, are now increasingly controlled through vaccination.

Health experts note that the benefits extend beyond immediate survival. Preventing disease reduces financial strain on families, limits disruptions to education, and eases pressure on healthcare systems.

The WHO estimates that every life saved through vaccination translates into decades of healthy living, highlighting the long-term social and economic impact of immunisation.

As Pakistan marks another year of progress, global health officials stress that continued commitment to vaccination, alongside efforts to counter misinformation, will be critical to sustaining and expanding these gains.
