Tardigrade and vaccine transport
A bizarre looking creature that may help us make vaccines last longer to move them across the globe. It is less than a millimetre long but the tardigrade is tough - really tough! Its extraordinary survival abilities may hold the key to helping us extend the shelf life of both blood and vaccines. This could extend the distances they can be transported, saving more lives.
