Gavi, the Vaccine Alliance

Ancient bacteria discovered in a Transylvanian ice cave could be our secret weapon against modern superbugs. Frozen for 5,000 years, these microbes contain unique enzymes and compounds that might inspire the next generation of life-saving antibiotics. Here’s what we know so far: bit.ly/4d8EGor

Two people have recently died in a bacterial meningitis outbreak in the south of England. Here’s what you need to know. bit.ly/4uy9nte via @ConversationUK

Reaching zero-dose children is often framed as a geographic challenge. But new evidence shows that household dynamics and gender norms can be just as decisive as physical access to services. Here's how social factors are quietly reshaping immunisation strategies: bit.ly/4lBsYop via @JSIhealth

A small shot for a big future. 💉✨ In the crowded camps of Cox’s Bazar, every vaccine is a shield for a Rohingya child. Through the EPI program, we are protecting the most vulnerable from preventable diseases. Thanks to @gavi for helping us turn vaccines into hope.

One of our most persistent global health challenges is how to find children who are missing from the system entirely. Not unvaccinated by choice, but invisible in the data. Here’s what new evidence reveals about those hidden gaps. bit.ly/4lBsYop via @JSIhealth

A vaccine is only as effective as the system that keeps it cold. In warm countries like Ethiopia, a faulty fridge can drift out of the safe temperature range within hours, putting entire stocks at risk. The challenge is identifying the few that fail in time, before doses are compromised.

For most of us, a common cold is just a week of tissues and mild annoyance. But for people suffering from asthma or chronic obstructive pulmonary disease (COPD), that same infection can lead to hospitalisations. New research from Yale explains how the usually harmless virus can trigger a life-threatening "cytokine storm" deep in the lungs. bit.ly/4uzDu3m

George Washington’s most deadly enemy in the Revolutionary War wasn’t the British... it was smallpox. Faced with a lethal, invisible threat, Washington made a controversial gamble to inoculate his entire army that helped him win the war. bit.ly/4rwXssP via @undarkmag

"Time is no longer against me because the facility is 24 hours light.” Moving read on how solar energy is transforming maternal care and immunisation services in rural Uganda, ensuring no mother endures giving birth in the dark and no health worker is forced to carry out lifesaving work by torchlight: bit.ly/4sNyHd5

To address ongoing reporting of #cholera cases, #Malawi 🇲🇼 rapidly rolled out a mobile outreach oral cholera vaccination campaign in 4 priority districts, with support from @WHO, @gavi and partners. The 5-day campaign surpassed the 95% coverage target bit.ly/4cUcdCG

Here’s how solar energy is making a “night and day” difference for health in Uganda: bit.ly/4sNyHd5

In December, a new solar power system was installed, leading to better working conditions, safer births for mothers and vaccines that are properly and consistently chilled.

At Nakifuma Health Centre III in Uganda, the power used to be "more off than on," leaving life-saving care at the whims of an unstable grid. That all changed in December. 🧵

Scientists are investigating how to turn mosquitoes into “flying vaccines” to target deadly viruses like Nipah and rabies right at their source.

Every year, the Global Polio Eradication Initiative (GPEI) vaccinates up to 440 million children against polio while strengthening health systems, supporting routine immunisation and responding to other health emergencies. We're proud to work closely with the Polio Oversight Board, GPEI partners and countries and look forward to continue working closely together to #EndPolio, while ensuring that this final phase leaves behind stronger, more resilient immunisation systems aligned with country priorities.
