World Immunization Week Highlights the Urgency of Global Vaccine Access
UNITED NATIONS, Apr 30 (IPS) – For 2025, the theme of World Health Immunization Week (24-30 April), “Immunization for All is Humanly Possible”, emphasizes the need to eradicate disparities in access to vaccines, particularly for children. By encouraging governments to implement vaccination programs at the local and national levels, the World Health Organization (WHO) seeks t0 ensure worldwide access to life-saving vaccines.
“Vaccines are among the most powerful inventions in history, making once-feared diseases preventable,” said Who Director-General, Dr Tedros Adhanom Ghebreyesus. “Thanks to vaccines, smallpox has been eradicated, polio is on the brink, and with the more recent development of vaccines against diseases like malaria and cervical cancer, we are pushing back the frontiers of disease. With continued research, investment and collaboration, we can save millions more lives today and in the next 50 years.”
According to figures from the United Nations (And), over the past 50 years global immunization efforts have saved roughly 154 million lives. Vaccines are also estimated to save around 4.2 million lives each year. More children live to see their first birthday and beyond than ever before in human history.
Health experts have estimated that immunization is one of the most cost-effective disease treatments, with every 1 dollar invested in vaccinations yielding a 54 dollar return in productivity. Additionally, vaccines are estimated to save the average infected person around 66 years of life, with roughly 20 million people having been spared of paralysis due to polio vaccinations.
Gavi, the Vaccine Alliancereported that in 2024, more than 5 million children who had not received a single dose of an essential vaccine were immunized in 20 vulnerable countries, many of which were in Africa. Gains in public health were most notably observed in Uganda, Chad, Cameroon, Ethiopia, Mozambique, Malawi, Madagascar, and Côte d’Ivoire.
In the past year alone, cases of polio type 1 have decreased in these regions by roughly 65 percent. Additionally, Human papillomavirus (HPV) vaccination coverage has increased by 28 percent as a result of this campaign, making Africa the region with the second highest coverage rate for HPV vaccinations.
Despite recent improvements, rates of global immunization have begun to slip in recent years due to humanitarian crises, recent cuts in funding, and public doubt surrounding the efficacy and implications of child vaccinations. Humanitarian organizations have expressed concern due to the rise or re-emergence of several public health concerns. According to a study conducted by WHOroughly 50 percent of people across 108 countries are experiencing moderate to severe disruptions to immunization services.
“The progress seen across African countries – bolstered by an unprecedented record of co-financing toward vaccine programmes in 2024 by African governments – demonstrates the tangible impact of sustained commitment,” said Thabani Maphosa, Chief Country Delivery Officer at Gavi, the Vaccine Alliance. “However, this momentum must not stall. Conflict, population growth, displacement, and natural disasters are creating ideal conditions for outbreaks to emerge and spread. Investing in immunization and securing sufficient funding for Gavi to carry out its mission over the next five years is essential to protect our collective future.”
According to the United Nations Children’s Fund (UNICEF), the recorded cases of measles reached a total of 10.3 million in 2023, marking a 20 percent increase from the previous year. It is projected that measles cases have risen sharply in 2024 and 2025.
Additionally, rates of meningitis infections have been on an upward trend in 2024 and 2025. Health experts have dubbed the recent rise in meningitis cases in sub-Saharan Africa as the “meningitis belt”, fearing that low and middle-income communities have been hit the hardest.
In 2024, there were nearly 26,000 cases of meningitis and 1,400 deaths across 24 countries. From January to March 2025, there have been approximately 5,500 suspected cases of meningitis and roughly 300 recorded deaths in 22 countries. Health experts also recorded re-emerging malaria and yellow fever epidemics.
In order to ensure global public health and maximize quality of life, it is imperative for governments to invest in health systems that benefit all walks of life, maximize disease surveillance, and tackle persisting cultural taboos surrounding immunization. However, recent cuts in funding threaten to undo decades of progress.
“The global funding crisis is severely limiting our ability to vaccinate over 15 million vulnerable children in fragile and conflict-affected countries against measles,” said UNICEF Executive Director Catherine Russell. “Immunization services, disease surveillance, and the outbreak response in nearly 50 countries are already being disrupted – with setbacks at a similar level to what we saw during COVID-19. We cannot afford to lose ground in the fight against preventable diseases.”
Although many local governments would consider allocating funds for vaccination services as financial losses, Gavi reports that investing in immunization campaigns and programs nets significant financial gains. In recognition of World Immunization Week, UNICEF, WHO, and Gavi released a joint report that detailed the results of the Expanded Programme on Immunization (EPI) in Bangladesh.
The report found that Bangladesh’s EPI has saved roughly 94,000 lives, prevented 5 million child cases of child infections, and yielded a 25 dollar return per 1 dollar of U.S. funding invested. Additionally, as a result of this model, Bangladesh has managed to increase the coverage of fully immunized children from 2 percent to over 81 percent since 1979.
“The need to maintain investments in immunization to improve health security and protect populations from vaccine-preventable diseases has never been more urgent if we are to sustain the progress and tangible impact seen across Bangladesh and South-East Asian countries,” said Sam Muller, Regional Head, Core Countries at Gavi, the Vaccine Alliance. “It is important that Gavi is fully funded for its next strategic period from 2026 to 2030, and governments continue their remarkable commitment to the lifesaving power of vaccines.
