UK health officials have issued a warning to travellers due to a shortage of rabies vaccines, critical for preventing a deadly viral infection prevalent in many overseas destinations. The Foreign Office-supported Travel Health Pro website recently highlighted that rabies remains ‘nearly always fatal’ in humans once symptoms begin, underscoring the urgent need for vaccination ahead of travel to high-risk areas.
Currently, two primary rabies vaccines—Bavarian Nordic’s Rabipur and Sanofi’s Verorab—are in limited supply, raising concerns for those planning trips abroad. Rabies is a viral infection primarily spread through contact with the saliva of infected wild or domestic animals, typically via bites, scratches, or when saliva comes into contact with broken skin or mucous membranes such as the eyes, mouth, or nose.
Interestingly, bats within the UK can carry rabies, though the risk is generally higher in other countries. The disease attacks the central nervous system, causing progressive damage to the brain and spinal cord. Once clinical symptoms manifest, rabies is almost always fatal, which is why prevention through vaccination and prompt medical attention after possible exposure is vital.

Travel Health Pro has advised medical practitioners to prioritize vaccine distribution due to current shortages. They emphasized that while human rabies cases are rare and often underreported, the disease is estimated to cause approximately 59,000 deaths globally each year. Moreover, although confirmed rabies cases in travellers are uncommon, any exposure to potentially rabid animals is a serious risk given the fatal nature of the disease.
The key preventive measures include avoiding contact with unknown animals, understanding the risks in endemic areas, and seeking immediate medical care following any bites or scratches from animals that might be infected. This advisory aims to raise awareness among travellers and healthcare providers to mitigate the risks posed by this deadly virus during vaccine scarcity.
