Since launching HPV vaccines in 2014, South Africa is reporting an 80% drop in infections with the HPV types responsible for most cervical cancers. Here’s how school-based HPV vaccination programmes are driving success in a country with one of the world’s highest burdens of cervical cancer: bit.ly/4BonuVu
Recent research suggests that undernourished children may mount weaker immune responses to some vaccines, potentially leaving them more vulnerable to infection. Linda Geddes breaks down the latest research: bit.ly/48agfmB

The XFG COVID-19 variant has been circulating since at least January 2025 and now accounts for nearly half of sequenced samples worldwide. Here’s everything you need to know about the ‘American COVID’ variant: bit.ly/4eHSl5w
How do we reach and protect the millions of children around the world that have never received a single vaccine? It starts by putting vaccination blindspots on the map.
Geospatial modelling, surveys and routine data collections are revealing pockets of inequity, but experts say they must be refined to ensure children don’t fall through the cracks: bit.ly/4z7o7kK Via The Conversation
In Pakistan, doctors are reporting a troubling rise in children affected with SSPE, a brain disease linked to measles infections that is almost universally fatal.

1 vaccine, 3 doses, protection against 6 diseases!
The lifesaving #hexavalent vaccine protects against:
1. Diphtheria
2. Tetanus
3. Pertussis (whooping cough)
4. Hepatitis B
5. Polio (inactivated poliovirus)
6. Haemophilus influenzae type b (Hib)
Combining vaccines means fewer injections, making it easier to reach zero-dose children and reducing the burden on children, caregivers and health care workers.
From 2026-2030, we are ramping up the introduction and roll-out of the hexavalent vaccine, which is an important tool to reach the goal of a #polio-free world. #worldpolioday #EndPolio
Polio paralyzed @RAMESHFERRIS as a baby. The polio vaccine existed, but it was out of reach for his family in India. For more than 20 years, he has urged the world to finish the job so every child can grow up polio-free. Read his story this #worldpolioday: gatesnot.es/488iCpU #EndPolio @gatesfoundation
How did a polio strain circulating in Pakistan infect a girl in Malawi who had never left her home? This case from 2022 is a warning that as long as polio persists anywhere, it’s a threat everywhere: bit.ly/45HRVbm #EndPolio #worldpolioday
"If these health workers saved our children before, they will save them again." -- Hauwa'u, a mother in Sokoto. Trust is the most powerful tool in healthcare. Here's how the relationships built during polio campaigns are now unlocking vaccine confidence for all childhood diseases in Nigeria. bit.ly/3Rs5pDn #EndPolio #WorldPolioDay
Kids today may not remember polio, but their grandparents likely do.
That’s why @Rotary‘s Dr. Arthur Lavin, founder of @GrandparentsFV, is collecting their stories. Grandparents’ memories teach younger generations what life was like before vaccines protected children from polio, and remind families why vaccines still matter today: bit.ly/3TSexD7 #EndPolio #WorldPolioDay
“For me, vaccination represents a promise of health and fulfillment to children.”
Djeneba shares a moment of joy with her daughter, Aïssata, 8 months, who just got vaccinated against polio in Mali.
Aïssata is one of the many children reached during a nationwide vaccination campaign to #EndPolio.
After the virus was detected in 2023 – with new cases as recently as April 2026 – the government, health workers, parents, @UNICEF and partners are working together to protect the health of every child.
