Is vaccine hesitancy bringing back diseases we thought were gone?
The reason? It's not that science has changed. It's that vaccination rates have taken a hit.
While many parents are still staying on schedule with their kids' shots, more and more are skipping or delaying vaccines. Maybe it's because of fear, confusion, or something they saw online but the result is the same: more outbreaks of diseases we actually know how to prevent. And kids, especially little ones, are paying the price.
14 million kids missed vaccines in 2024
Yes, you read that right. According to new reports from WHO and UNICEF, over 14 million children didn't get a single vaccine in 2024. That's not just a blip. It's a big deal.
Nine countries accounted for over half of those unvaccinated kids, but the ripple effect is global. Even though a few more kids got at least one dose compared to 2023, the numbers still fall short of what's needed. Nearly 20 million infants missed at least one shot in the DTP (diphtheria, tetanus, pertussis) series, and 14.3 million didn't get any vaccines at all.
That's 1.4 million more than in 2019—so instead of moving forward, we're sliding backward.
Wait—Is measles actually back?
Unfortunately, yes. In 2000, the U.S. proudly declared measles eliminated. But fast forward to 2024, and there were over 300 confirmed cases, mostly in kids who hadn't been vaccinated.
And let's not downplay this—measles isn't just a fever and a rash. It's insanely contagious (like, one infected person can spread it to 90% of people nearby who aren't immune).
It can cause pneumonia, brain swelling, and in some cases, it's deadly.
And it's not just measles making a comeback. Polio, whooping cough, even chickenpox—these are all creeping back into communities where vaccine hesitancy has taken root.
Why is this happening?
Honestly, part of the problem is that vaccines have worked too well. Most people today haven't seen these diseases in real life, so they've stopped feeling scary. When you don't see the damage, it's easier to doubt the cure.
And then there's the internet. Misinformation spreads fast—especially when it's coming from influencers, conspiracy theorists, or people pretending to be experts. Throw in a little fear and a few 'my friend's cousin's kid had a bad reaction' stories, and suddenly, vaccines start looking suspicious. But here's the truth: vaccines are one of the best tools we've ever had for protecting kids and saving lives.
What happens when too many skip shots?
Here's the thing about vaccines—they don't just protect the person getting the shot.
They protect everyone around them. It's called herd immunity, and it's the reason some diseases were nearly wiped out in the first place.
But when vaccine rates drop, herd immunity collapses. Suddenly, these diseases can spread like wildfire.
Imagine a school where only 80% of the kids are vaccinated for measles (way below the recommended 95%). If one infected kid shows up, the virus can fly through that classroom, infecting not just the unvaccinated but also anyone with a weak immune system.
It quickly turns from a 'personal choice' into a public health crisis. Schools may need to shut down, hospitals get overwhelmed, and families are left scrambling. And all of it? Completely avoidable.
So what should parents know?
If you're a parent who's unsure or nervous about vaccines, you're not alone. It's totally okay to ask questions. Just make sure you're getting answers from real experts—like your pediatrician or health agencies—not random YouTube videos or Facebook groups.
Ask about ingredients, timelines, side effects, long-term studies—whatever's on your mind. Doctors have heard it all before, and they want to help you feel confident about your decision.
Also, remember: vaccinating your child isn't just about them. It's about protecting your neighbor's newborn, your kid's classmate going through chemo, or your elderly aunt with a weak immune system. It's a simple way to keep everyone safe.

Always talk to your child's doctor or a trusted healthcare provider before making decisions about vaccines or your family's health. Everyone's situation is different, so make sure you're getting advice that's right for you.

"We Hear Children Die Every Day Of Hunger": Gaza Babies Struggle To Survive
Jerusalem: In a makeshift tent on a Gaza beach, three-month-old Muntaha's grandmother grinds up chickpeas into the tiniest granules she can to form a paste to feed the infant, knowing it will cause her to cry in pain, in a desperate race to keep the baby from starving. "If the baby could speak, she would scream at us, asking what we are putting into her stomach," her aunt, Abir Hamouda, said. Muntaha grimaced and squirmed as her grandmother fed her the paste with a syringe. Muntaha's family is one of many in Gaza facing dire choices to try to feed babies, especially those below the age of six months, who cannot process solid food. Infant formula is scarce after a plummet in aid access to Gaza. Many women cannot breastfeed due to malnourishment, while other babies are separated from their mothers due to displacement, injury, or, in Muntaha's case, death. Her family says the baby's mother was hit by a bullet while pregnant, gave birth prematurely while unconscious in intensive care, and died a few weeks later. The director of the Shifa Hospital described such a case in a Facebook post on April 27, four days after Muntaha was born. "I am terrified about the fate of the baby," said her grandmother, Nemah Hamouda. "We named her after her she can survive and live long, but we are so afraid, we hear children and adults die every day of hunger." Muntaha now weighs about 3.5 kilograms, her family said, barely more than half of what a full-term baby her age would normally weigh. She suffers stomach problems like vomiting and diarrhoea after feeding. Health officials, aid workers, and Gazan families told Reuters many families are feeding infants herbs and tea boiled in water, or grinding up bread or sesame. Humanitarian agencies also reported cases of parents boiling leaves in water, eating animal feed, and grinding sand into flour. Feeding children solids too early can disrupt their nutrition, cause stomach problems, and risk choking, paediatric health experts say. "It's a desperate move to compensate for the lack of food," said UNICEF spokesperson Salim Oweis. "When mothers can't breastfeed or provide proper infant formula, they resort to grinding chickpeas, bread, rice, anything that they can get their hands on to feed their children... it is risking their health because these supplies are not made for infants to feed on." Baby bottles without milk Gaza's spiralling humanitarian crisis prompted the main world hunger monitoring body on Tuesday to say a worst-case scenario of famine is unfolding and immediate action is needed to avoid widespread death. Images of emaciated Palestinian children have shocked the world. Gazan health authorities have reported more and more people dying from hunger-related causes. The total so far stands at 154, among them 89 children, most of whom died in the last few weeks. With the international furore over Gaza's ordeal growing, Israel announced steps over the weekend to ease aid access. But the UN World Food Programme said on Tuesday it was still not getting the permissions it needed to deliver enough aid. Israel and the US accuse militant group Hamas of stealing aid, which the militants deny, and the UN of failing to prevent it. The UN says it has not seen evidence of Hamas diverting much aid. Hamas accuses Israel of causing starvation and using aid as a weapon, which the Israeli government denies. Humanitarian agencies say there is almost no infant formula left in Gaza. The cans available in the market cost over $100 – impossible to afford for families like Muntaha's, whose father has been jobless since the war closed his falafel business and displaced the family from their home. In the paediatric ward of Al-Aqsa Martyrs Hospital in the central Gaza city of Deir al-Balah, the infant formula supply is mostly depleted. One mother showed how she poured thick tahini sesame paste into a bottle and mixed it with water. "I am using this instead of milk, to compensate her for milk, but she won't drink it," said Azhar Imad, 31, the mother of four-month-old Joury. "I also make her fenugreek, anise, caraway, any kind of herbs (mixed with water)," she said, panicked as she described how instead of nourishing her child, these attempts were making her sick. Medical staff at the hospital spoke of helplessness, watching on as children's health deteriorated with no way to safely feed them. "Now, children are being fed either water or ground hard legumes, and this is harmful for children in Gaza," said Doctor Khalil Daqran. "If the hunger continues ... within three or four days, if the child doesn't get access to milk immediately, then they will die," he said.

Breast Milk For Sale: Mothers Making Millions Online. But Is It Safe For Other Babies?
Last Updated: Women in the US are earning millions by selling breast milk, but is it safe for babies? Discover 5 essential facts about the benefits and risks of buying breast milk Breastfeeding is on the rise across the United States, with an increasing number of women choosing to nurse their infants rather than rely on formula. As this trend gains momentum, an intriguing development has come to light: many women are now earning up to $1,000 (approximately Rs 87,000) per month by selling their surplus breast milk. Online communities on platforms like WhatsApp and Facebook have emerged, where individuals prioritise purchasing breast milk over formula, believing it to offer superior health benefits. Remarkably, some bodybuilders are also reported to consume breast milk for its perceived nutritional value. Why Is Breast Milk Considered Unique? Health experts widely agree that breast milk offers numerous benefits for both the baby and the mother. It contains essential nutrients, antibodies, proteins, and healthy fats that support immunity and development. The first form of breast milk, colostrum, is often referred to as the baby's 'first vaccine' due to its protective qualities. For babies, breast milk plays a vital role in both physical and cognitive development. For mothers, breastfeeding supports postpartum recovery, strengthens emotional bonding, and may reduce the risk of breast and ovarian cancer. It is also a safe, natural, and cost-effective source of nourishment during the early months of life. The World Health Organisation (WHO) and UNICEF recommend exclusive breastfeeding for the first six months of a baby's life, citing its unmatched health benefits. The Risks Of Buying Breast Milk Despite its growing popularity, the US Food and Drug Administration (FDA) strongly advises against buying or feeding breast milk obtained from unregulated sources. While sharing breast milk may appear harmless, it can pose serious health risks, especially if the donor's medical history is unknown. Diseases such as HIV, hepatitis B and C, and various bacterial infections can be transmitted through breast milk. Improper storage and handling can also lead to bacterial contamination, potentially making the milk unsafe or even fatal for infants. Additionally, some sellers may engage in unhealthy practices to increase milk production, potentially compromising its nutritional quality. Without proper medical supervision or laboratory testing, purchasing and using breast milk from informal sources can be highly risky. A Global Phenomenon With Ongoing Debate The trend of selling breast milk is not limited to the United States, it's observed in several other countries as well. However, the safety concerns highlighted by health authorities remain universally relevant. As demand grows, so too does the debate about regulation, safety, and ethics surrounding the informal breast milk market.
