Global vaccination efforts stall, leaving millions of children vulnerable to preventable diseases
Efforts to vaccinate children globally have stalled since 2010, leaving millions vulnerable to tetanus, polio, tuberculosis, and other diseases that can be easily prevented. Protection from measles, in particular, dropped in 100 countries between 2010 and 2019, unraveling decades of progress, including in rich countries that had previously eliminated the highly infectious disease, according to a new analysis of global vaccination trends published Tuesday in the journal Lancet.
'After clean water, vaccination is the most effective intervention for protecting the health of our children,' said Helen Bedford, a professor of children's health at University College London, who was not connected to the research. She warned there has been a small but worrying rise in the number of parents skipping vaccination for their children in recent years for reasons including misinformation. In Britain, Bedford said that has resulted in the largest number of measles cases recorded since the 1990s and the deaths of nearly a dozen babies from whooping cough. Vaccination rates in the US are also falling, and exemptions from vaccinations are at an all-time high.
After the World Health Organization established its routine immunization program in 1974, countries made significant efforts to protect children against preventable and sometimes fatal diseases; the program is credited with inoculating more than 4 billion children, saving the lives of 154 million worldwide. Since the program began, the global coverage of children receiving three doses of the diphtheria–tetanus–whooping cough vaccine nearly doubled from 40 percent to 81 percent. The percentage of kids getting the measles vaccine also jumped from 37 percent to 83 percent, with similar increases for polio and tuberculosis.
But after the COVID-19 pandemic, coverage rates dropped, with an estimated 15.6 million children missing out on the diphtheria–tetanus–whooping cough vaccine and the measles vaccine. Nearly 16 million children failed to get vaccinated against polio, and 9 million missed out on the TB vaccine, with the biggest impact in sub-Saharan Africa. The study was funded by the Bill & Melinda Gates Foundation and Gavi, The Vaccine Alliance. Researchers at the Institute for Health Metrics and Evaluation at the University of Washington, who conducted the analysis, noted that more than half of the world's 15.7 million unvaccinated children live in just eight countries in 2023: Nigeria, India, Congo, Ethiopia, Somalia, Sudan, Indonesia, and Brazil.
Since former President Trump began to withdraw the US from the WHO and dismantled the US Agency for International Development, public health experts have warned of new epidemics of infectious diseases. The researchers said it was too early to know what impact recent funding cuts might have on children's immunization rates. The WHO said there had been an eleven-fold spike in measles in the Americas this year compared to 2024. Measles infections doubled in the European region in 2024 versus the previous year, and the disease remains common in Africa and Southeast Asia.
'It is in everyone's interest that this situation is rectified,' said Dr. David Elliman, a pediatrician who has advised the British government, in a statement. 'While vaccine-preventable infectious diseases occur anywhere in the world, we are all at risk.'

Children in Pakistan among millions under threat as vaccine coverage faltering — study
PARIS: Efforts to vaccinate children against deadly diseases are faltering across the world due to economic inequality, Covid-era disruptions and misinformation, putting millions of lives at risk, research warned Wednesday. These trends all increase the threat of future outbreaks of preventable diseases, the researchers said, while sweeping foreign aid cuts threaten previous progress in vaccinating the world's children. A new study published in The Lancet journal looked at childhood vaccination rates across 204 countries and territories. It was not all bad news. An immunization program by the World Health Organization was estimated to have saved an estimated 154 million lives over the last 50 years. And vaccination coverage against diseases such as diphtheria, tetanus, whooping cough, measles, polio and tuberculosis doubled between 1980 and 2023, the international team of researchers found. However the gains slowed in the 2010s, when measles vaccinations decreased in around half of the countries, with the largest drop in Latin America. Meanwhile in more than half of all high-income countries there were declines in coverage for at least one vaccine dose. Then the Covid-19 pandemic struck. Routine vaccination services were hugely disrupted during lockdowns and other measures, resulting in nearly 13 million extra children who never received any vaccine dose between 2020 to 2023, the study said. This disparity endured, particularly in poorer countries. In 2023, more than half of the world's 15.7 million completely unvaccinated children lived in just eight countries, the majority in sub-Saharan Africa, according to the study. In the European Union, 10 times more measles cases were recorded last year compared to 2023. In the United States, a measles outbreak surged past 1,000 cases across 30 states last month, which is already more than were recorded in all of 2024. Cases of polio, long eradicated in many areas thanks to vaccination, have been rising in Pakistan and Afghanistan, while Papua New Guinea is currently enduring a polio outbreak. 'Routine childhood vaccinations are among the most powerful and cost-effective public health interventions available,' said senior study author Jonathan Mosser of the US-based Institute for Health Metrics and Evaluation (IHME). 'But persistent global inequalities, challenges from the COVID pandemic, and the growth of vaccine misinformation and hesitancy have all contributed to faltering immunization progress,' he said in a statement. In addition, there are 'rising numbers of displaced people and growing disparities due to armed conflict, political volatility, economic uncertainty, climate crises,' added lead study author Emily Haeuser, also from the IHME. The researchers warned the setbacks could threaten the WHO's goal of having 90 percent of the world's children and adolescents receive essential vaccines by 2030. The WHO also aims to halve the number of children who have received no vaccine doses by 2030 compared to 2019 levels. Just 18 countries have achieved this so far, according to the study, which was funded by the Gates Foundation and the Gavi vaccine alliance. The global health community has also been reeling since President Donald Trump's administration drastically slashed US international aid earlier this year. 'For the first time in decades, the number of kids dying around the world will likely go up this year instead of down because of massive cuts to foreign aid,' Bill Gates said in a separate statement on Tuesday. 'That is a tragedy,' the Microsoft co-founder said, committing $1.6 billion to Gavi, which is holding a fund-raising summit in Brussels on Wednesday.

Trump administration authorizes $30 million for Israeli-backed group distributing food in Gaza
WASHINGTON: The Trump administration has authorized providing $30 million to a US- and Israeli-backed group that is distributing food in Gaza, a US official said Tuesday, an operation that has drawn criticism from other humanitarian organizations. The request is the first known US government funding for the Gaza Humanitarian Foundation's aid distribution efforts amid the Israel-Hamas war. The American-led group had applied for the money to the US Agency for International Development, which has been dismantled and will soon be absorbed into the State Department as part of the Trump administration's deep cuts of foreign aid. The application is part of a controversial development: private contracting firms led by former US intelligence officers and military veterans delivering aid to some of the world's deadliest conflict zones in operations organized with governments that are combatants in the conflicts. The official, who spoke on condition of anonymity to discuss a sensitive diplomatic issue involving a controversial aid program, said the decision to directly fund GHF was made 'to provide effective and accessible humanitarian aid to the people of Gaza.' The announcement comes as violence and chaos have plagued areas near the new food distribution sites since opening last month. GHF says no one has been killed at the aid sites themselves and that it has delivered some 44 million meals to Palestinians in need. Palestinian witnesses and health officials say Israeli forces have repeatedly opened fire on crowds heading to the sites for desperately needed food, killing hundreds in recent weeks. The Israeli military says it has fired warning shots at people it said approached its forces in a suspicious manner while going to the sites. Witnesses said Israeli troops opened fire as crowds tried to reach a GHF site on Tuesday in southern Gaza. At least 19 were killed and 50 others wounded, according to Nasser hospital and Gaza's Health Ministry. The Israeli military did not immediately comment. Israel wants the GHF to replace a system coordinated by the United Nations and international aid groups. Along with the United States, it accuses Hamas of stealing aid, without offering evidence. The United Nations, its affiliated aid agencies and private humanitarian groups that work in Gaza have denied that there has been any significant theft of their supplies by Hamas. The Associated Press reported Saturday that the American-led group had asked the Trump administration for the initial funding so it can continue its aid operation, which has been criticized by the UN, humanitarian groups and others. They accuse the foundation of cooperating with Israel's objectives in the 21-month-old war against Hamas in a way that violates humanitarian principles. State Department spokeswoman Tammy Bruce told reporters earlier Tuesday that she had no information to provide on funding for the foundation.
