Over 14 million infants missed all vaccines in 2024, warn WHO and UNICEF
More than half of the world's unvaccinated infants are in nine countries — Nigeria, India, Sudan, the Democratic Republic of Congo, Ethiopia, Indonesia, Yemen, Afghanistan, and Angola.
While these nations account for a large share of zero-dose children, it's important to note that high overall coverage can still exist alongside high absolute numbers. For example, India recorded 909,000 unvaccinated infants in 2024, about 6 per cent of the global total, despite reaching 96 per cent vaccine coverage among 22.7 million infants.
Vaccination coverage steady, but below target
Global childhood vaccination rates showed marginal improvement in 2024:
89 per cent of infants received at least one dose of the DTP vaccine (against diphtheria, tetanus and pertussis/ whooping cough).
85 per cent completed the recommended three-dose series.
Around 20 million infants missed at least one dose of DTP-containing vaccine last year.
84 per cent received the first dose of measles vaccine
Global coverage for the first dose of HPV vaccine in girls grew from 27 per cent in 2023 to 31 per cent in 2024.
Coverage of yellow fever vaccine in the countries at risk of it is 50 per cent, well below the recommended 80 per cent.
Funding, misinformation and added challenges
UN officials expressed concern about the slashed health aid budgets. 'Vaccines save lives, allowing individuals, families, communities, economies and nations to flourish,' said Tedros Adhanom Ghebreyesus, WHO Director-General. 'Drastic cuts in aid, coupled with misinformation about the safety of vaccines, threaten to unwind decades of progress.'
The report highlights that around 10.2 million unvaccinated or under-vaccinated infants live in countries facing conflict or social and institutional instability. These children are the most vulnerable to disease outbreaks and urgently need focused support.
Why vaccines still matter
Vaccines save up to five million lives every year, according to WHO. Unvaccinated children are significantly more vulnerable to life-threatening diseases, which can also spread rapidly through communities when herd immunity falters.
While stabilising coverage is a step forward, the continued presence of over 14 million zero-dose infants is a global red flag. Unless urgent action is taken, health experts warn that progress made over decades in childhood immunisation could unravel, leaving the world vulnerable to preventable but deadly disease outbreaks.
To reach every child, WHO and UNICEF calls for:
1. Targeted funding for countries with the highest zero-dose populations
2. Better delivery mechanisms in fragile and conflict-affected regions
3. Strong public messaging to combat vaccine hesitancy and disinformation
4. Investing in better data and disease surveillance systems for high-impact immunization programmes.

Loneliness is the new silent killer: WHO warns of a global health crisis in a hyperconnected world
We've never been more connected, yet so many of us feel deeply alone. In a world filled with social media, video calls, and instant messages, loneliness is quietly becoming a major health crisis. A new report from the World Health Organization (WHO) reveals a shocking truth: loneliness is now linked to over 871,000 deaths every year. It's not just about feeling sad or isolated; it's harming our bodies and minds. From heart problems to depression, the effects are real. As this silent epidemic grows, it's time we take loneliness seriously and start rebuilding the human connections we all need. Loneliness is becoming a global health crisis despite digital connection In an era where we are constantly plugged into digital networks, sending texts, reacting with emojis, and hopping on video calls, a silent epidemic is claiming lives at an alarming rate. A new report by the World Health Organization (WHO), From Loneliness to Social Connection: Charting the Path to Healthier Societies , reveals a disturbing global paradox: despite unprecedented connectivity, loneliness is emerging as one of the most pressing public health threats of our time. According to the report, over 871,000 people die each year due to the direct and indirect effects of loneliness. That's more than 100 people every hour, a figure that rivals the global death tolls from major diseases such as heart conditions and diabetes. Far from being a fleeting emotional state, loneliness is now recognised as a risk factor for serious health issues, both physical and mental. What loneliness really means and why it affects our health The WHO defines loneliness as the gap between the relationships people have and the ones they desire. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Gentle Japanese hair growth method for men and women's scalp Hair's Rich Learn More Undo It's not merely the state of being alone but the painful feeling of being emotionally or socially disconnected. Social isolation, the objective lack of social contact, is closely related, and both conditions can lead to devastating consequences. Mounting research links loneliness to an array of health problems, including stroke, heart disease, dementia, depression, anxiety, diabetes, and even premature death. The report underscores that strong social connections act as a 'biological buffer,' reducing inflammation, regulating stress hormones, improving mental well-being, and potentially extending life expectancy. The hidden social and economic causes behind the loneliness epidemic Despite the global reach of smartphones and social media, our digital lives often lack depth. Likes, comments, and brief messages may create an illusion of interaction, but they rarely substitute for the meaningful relationships that humans truly need. As Chido Mpemba, co-chair of the WHO Commission on Social Connection, points out, even young people immersed in digital environments often report feeling profoundly alone. But screen time isn't the sole culprit. The loneliness crisis is deeply rooted in a complex web of socioeconomic and cultural factors: Poor health and disability can restrict social participation. Economic hardship leads to stress and fewer social opportunities. Urbanisation and sprawling cities have diminished traditional community spaces. A culture of hyper-independence often prizes productivity over personal connection. Lack of accessible education and shared social infrastructure can further isolate individuals. All these factors contribute to a world where forming and maintaining deep social bonds is becoming increasingly difficult. Why the WHO wants loneliness treated as a public health priority To tackle this crisis, the WHO urges governments and institutions to recognise loneliness not as a personal failing but as a systemic health issue. The report outlines a multifaceted approach to addressing the problem, calling for Policy changes that promote community engagement and inclusive urban planning Investment in research to better understand loneliness and how to combat it New ways to measure social connection and isolation, allowing for better monitoring and targeted interventions Public campaigns that encourage acts of connection, such as initiating conversations with strangers or joining local groups Above all, the WHO stresses that social connection should be treated as a core component of public health, just as vital as access to clean water, nutrition, or vaccines. How to rebuild human connection and overcome loneliness in today's fragmented world The loneliness epidemic is not an inevitable consequence of modern life but a result of systems and priorities that undervalue human connection. While there's no quick fix, even small, intentional acts, like a shared meal, a walk with a friend, or a supportive workplace, can begin to restore a sense of belonging. If societies fail to act, loneliness will continue to erode not only individual health but also the social fabric that binds communities together. The time to treat connection as essential to well-being is now because, in the end, our lives may depend on it. Also Read: Can't sleep?

7000 is the new 10,000 steps, finds study
For decades, fitness trackers and health apps have urged users toward the same daily goal: 10,000 steps. But new research suggests that even taking 7,000 steps a day brought significant reductions in the risk of death and major diseases. Importantly, the research found that health benefits began accumulating well before reaching either 7,000 or 10,000 steps. (Representative file photo) A comprehensive analysis of studies published between Jan 1, 2014, and Feb 14, 2025 on Thursday in The Lancet Public Health has found that taking 7,000 steps a day almost halved the risk of death and cardiovascular disease, and significantly reduced the likelihood of developing diseases such as type-2 diabetes, dementia and depression. The study, which analysed data from 57 studies involving more than 160,000 adults across 35 research cohorts, represents the most extensive examination to date of how daily step counts affect health outcomes beyond just mortality. The researchers particularly stressed on the less daunting nature of the goal. 'Although 10,000 steps per day can still be a viable target for those who are more active, 7,000 steps per day is associated with clinically meaningful improvements in health outcomes and might be a more realistic and achievable target for some,' the researchers wrote. The 10,000-step target has long been accepted as a gold standard for daily activity, appearing on fitness devices and in public health messaging worldwide. But its origins lie not in rigorous scientific research but in a 1960s Japanese marketing campaign. The number comes from Manpo-kei, a pedometer sold in Japan in 1965 whose name translates to '10,000 steps meter.' The company chose this round number partly because the Japanese character for 10,000 resembles a walking person — a clever bit of marketing that has influenced global health recommendations for decades. Current physical activity guidelines from the World Health Organization (WHO) focus primarily on minutes of moderate-to-vigorous activity rather than step counts, recommending at least 150 minutes of moderate-intensity activity per week, but have not established official step-count targets, citing insufficient evidence. 'Despite growing interest in step-based recommendations, the evidence available during the development of the 2018 Physical Activity Guidelines for Americans and the 2020 WHO Guidelines for Physical Activity and Sedentary Behaviour was considered insufficient to support the development of step count targets,' the study's authors noted. The new research examined eight health outcomes: all-cause mortality, cardiovascular disease, cancer, type 2 diabetes, cognitive outcomes including dementia, mental health, physical function, and falls. Compared with taking 2,000 steps per day — considered the lower bound of normal activity for older adults — participants who took 7,000 daily steps had: a 47% lower risk of all-cause mortality, 25% lower risk of cardiovascular disease, 47% lower risk of cardiovascular disease mortality, 37% lower risk of cancer mortality, 14% lower risk of type 2 diabetes, 38% lower risk of dementia and 22% lower risk of depressive symptoms. The likelihood of falls dropped by 28%. Importantly, the research found that health benefits began accumulating well before reaching either 7,000 or 10,000 steps. Even modest increases showed substantial improvements: people taking 4,000 steps daily had a 36% lower risk of death compared with those taking 2,000 steps. For most health outcomes, the researchers identified 'inflection points' — thresholds where additional steps provided diminishing returns. These typically occurred between 5,000 and 7,000 steps per day. 'For all outcomes, even very low step counts were associated with a risk reduction, and the HR continued to decrease with each 1,000 increment of step increase,' the authors wrote. 'Overall, the decrease in risk was attenuated before reaching 7,000 steps per day.' While taking 10,000 steps did provide additional benefits for some outcomes compared with 7,000 steps, the improvements were relatively small. For instance, 10,000 daily steps was associated with a 10% lower risk of all-cause mortality compared with 7,000 steps. The study revealed interesting variations based on age and the type of device used to measure steps. For all-cause mortality, the relationship was non-linear for younger adults, with benefits levelling off around 5,400 steps per day. For older adults, however, the relationship was linear, meaning continued benefits with each additional step. The analysis also addressed a key question for public health guidelines: whether different devices — accelerometers versus pedometers — produced similar results. The researchers found that 'the magnitude of association was similar at equivalent step counts, with minor differences in model fit for linear versus non-linear models.' The findings could have significant implications for public health messaging and individual motivation. Dr Ding Ding, the study's lead author from the University of Sydney, and colleagues suggest that emphasising a lower, more achievable target might encourage more people to become active. 'The message that every step counts for those who are able should be emphasised as a core public health message, regardless of the specific quantitative target,' the researchers wrote. The researchers acknowledged several limitations to their analysis. Most studies measured step counts at a single time point over just a few days, which 'might not accurately capture typical stepping patterns or changes over time.' Additionally, most data came from high-income countries, limiting the generalisability of findings to global populations. The researchers also noted that people with extremely low step counts might differ from more active individuals in health status and physical function, potentially affecting the results. 'Future research targeting low-income and middle-income countries and using harmonised meta-analysis and causal inference methods would further strengthen the evidence base,' they wrote.

Hunger grips war-torn Gaza: Around 2 million are now food insecure, ‘skeletal children fill hospital wards'
"Starvation is a horrific reality for children and families in Gaza," UNICEF posted on X social media recently. More than two million people in Gaza are facing severe food shortages, with more than 100 NGOs warning of "mass starvation". Meanwhile, more than 800 people have been killed in recent weeks trying to reach food, mostly in mass shootings by Israeli soldiers posted near Gaza Humanitarian Foundation distribution centers, Reuters reported. Besides, Israeli forces have killed nearly 60,000 Palestinians in airstrikes, shelling and shooting since launching their assault on Gaza in response to attacks on Israel by the Hamas group that killed 1,200 people and captured 251 hostages in October 2023. For the first time since the war began, Palestinian officials say dozens are now also dying of hunger. Gaza's health ministry said on Tuesday that 9,00,000 children are going hungry, and 70,000 already show signs of malnutrition. Meanwhile, the ward at the Patient's Friends Benevolent Society hospital was crowded with other skeletal children, some doubled up on the 12 beds, the Guardian reported. There are only two functioning paediatric teams left in Gaza City, and up to 200 children turn up daily seeking treatment. The chief of the World Health Organization said on Wednesday that Palestinians in Gaza are suffering from man-made 'mass starvation' due to the aid blockade on the enclave. Gaza has been witnessing its food stocks run out since Israel cut off all supplies to the territory in March and then lifted that blockade in May with new measures it says are needed to prevent aid from being diverted to militant groups. Despite a partial lift of the Israeli blockade on humanitarian truck entries in May, the food supplies that are getting into Gaza are insufficient, leaving 2.1 million people food insecure, CNN reported. Meanwhile, the United Nations said more than a thousand people have been killed by Israeli forces while seeking food since late May, when a new Israel- and US-backed aid group, the Gaza Humanitarian Foundation, began operating. 'Parents tell us their children cry themselves to sleep from hunger,' Director-General Tedros Adhanom Ghebreyesus was quoted by CNN as saying. 'Food distribution sites have become places of violence," he added. Adding to the woes of people in war-torn Gaza, the price of flour in Gaza has also risen sharply in recent months. As per the Guardian, flour is selling for more than 30 times the market rate at the start of the year.
