The medical research trust has renewed its call for recruits.

“The trial involves getting both the influenza and diphtheria-tetanus-pertussis (whooping cough) vaccines for free, and providing blood samples on several occasions,” a spokeswoman said.

“It is taking place in the Clifford Craig Research Trust.”

Researchers need healthy people aged 20 to 50 or older than 65. 

“You need to have not had your flu vaccine shot this year.”
