Illustration of a young child sitting against a pink textured background with playful shapes. Text reads: 'Measles protection requires two vaccine doses.' Below, a water drop icon is followed by: 'In 2024, only 84% of children got the 1st dose and just 76% received the 2nd dose.'

#Measles is preventable with two doses of vaccine.

Yet in 2024, 30+ million children remained under-protected, leading to more large or disruptive outbreaks.

Only 76% of children got the second dose, far below the 95% coverage needed to stop outbreaks 👉 bit.ly/4kFzSGW

Children living in countries facing conflict or fragility are 3x more likely to miss life-saving vaccines than those living in stable countries.

Conflicts and crises are putting childhood vaccinations at risk, threatening to undo years of progress.

New WHO & @unicef.org data shows the number of unvaccinated children in 13 crisis-affected countries rose from 3.6M in 2019 to 5.4M in 2024.

The Global Accelerator for Paediatric Formulations Network (GAP-f) is fast-tracking the development of medicines made for children—not just scaled-down versions of adult treatments.

Illustration of a small child standing next to a big ladder. Text reads 'Why are children put at risk with medicines that are not designed for their age?'. Below it, text reads '38-50% of medicines used for children are prescribed off-label.'

Too many children are given medicines that were never properly tested for them.

That means imprecise dosing—and real risks.

💡 The Global Accelerator for Paediatric Formulations Network (GAP-f) is changing the game.

Illustration showing a sleeping infant. Above the baby, text reads: “Global childhood immunization coverage remains strong.” Below, large text highlights: “85% infants were immunized in 2024.”

In 2024, 89% of infants received at least one dose of the diphtheria, tetanus and pertussis (DTP) vaccine, and 85% completed all three doses.

Global demand for childhood immunization is strong according to new data from WHO and @unicef.org 🔗 bit.ly/4kFzSGW

@who.int remains committed to end AIDS in our lifetime, and calls on leaders to:

Embrace meaningful partnerships — esp. with people living with #HIV;
 
Support HIV research;
 
Prioritize HIV prevention;
 
Protect human rights;
 
Reject the politicization of science and scientific institutions.

Text reads 'Why are children still waiting for medicines adults have had for years?' near the illustration of a child looking sad with balloons flying away. Text below reads 'Only 30% of essential medicines are available in child-appropriate formulations.'

Many essential medicines are not designed for children.

That means crushed pills, inaccurate doses, and bitter tastes that make treatment hard to take.

The Global Accelerator for Paediatric Formulations Network (GAP-f) is working to close this gap.

Text reads 'Lenacapavir (LEN) is a new drug to protect people at risk of HIV. WHO recommends LEN as an additional PrEP option for HIV prevention.' Light green background with illustration of a medicine bottle and a red ribbon.

Text reads 'Lenacapavir is the first twice-yearly injectable form of PrEP.' Below the text reads - Only 2 doses per year - Highly effective & long-acting - An alternative to daily pills - Designed to be discreet and convenient. Helps fight stigma' Light green background with illustration of a red ribbon.

Text reads 'Diverse HIV prevention options mean more ways for you to take control of your health.' Light green background with illustration of a small group of people smiling and a red ribbon.

⚠️ 1.3 million people acquired HIV in 2024 alone, including thousands of adolescent girls and young women.

Today, in a landmark move towards HIV prevention, WHO recommends twice-yearly injectable lenacapavir as pre-exposure prophylaxis (PrEP) to protect people at risk of HIV.

The United Nations agencies and humanitarian partners cannot overstate the urgency of this moment: fuel must be allowed into Gaza in sufficient quantities and consistently to sustain life-saving operations.

For the first time in 130 days, a small amount of fuel entered Gaza this week. This is a welcome development, but it is a small fraction of what is needed each day to keep daily life and critical aid operations running.

These conditions expose families to deadly disease outbreaks and push Gaza’s most vulnerable even closer to death.

Without fuel, bakeries and community kitchens cannot operate. Water production and sanitation systems will shut down, leaving families without safe drinking water, while solid waste and sewage pile up in the streets.

Roads and transport will remain blocked, trapping those in need. Telecommunications will shut down, crippling lifesaving coordination and cutting families off from critical information and from one another.

Without adequate fuel, Gaza faces a collapse of humanitarian efforts.

Hospitals are already going dark; maternity, neonatal and intensive care units are failing, and ambulances can no longer move.

Without adequate fuel, UN agencies responding to this crisis will likely be forced to stop their operations entirely, directly impacting all essential services in Gaza.

This means no health services, no clean water, and no capacity to deliver aid.

After almost two years of war, people in Gaza are facing extreme hardships, including widespread food insecurity. When fuel runs out, it places an unbearable new burden on a population teetering on the edge of starvation.

Fuel supplies are needed to move the fleet used for transporting essential goods across the Strip and to operate a network of bakeries producing fresh bread for the affected population. Without fuel, these lifelines will vanish for 2.1 million people.

Joint statement by OCHA, UNDP, UNFPA, UNOPS, UNRWA, WFP, and WHO on fuel shortage in Gaza.

The United Nations warns that the fuel shortage in Gaza has reached critical levels.

Fuel is the backbone of survival in #Gaza. It powers hospitals, water systems, sanitation networks, ambulances, and every aspect of humanitarian operations. 🧵
