World's first trial testing a mix of COVID19 vaccines on volunteers
A world-first study to find out if different types of Covid vaccines can be mixed is underway in Liverpool.
Medics at the city's School of Tropical Medicine will give shots of the Oxford/AstraZeneca and the Pfizer jabs several weeks apart. It is one of several sites across the country carrying out the tests.
The nurses carrying out the vaccinations are part of the schools Well Travelled Clinic - they have swapped their regular work vaccinating people ready for travel abroad, and are now working as part of the wider team's coronavirus research.
