It allows doctors to painlessly administer vaccines without the need to specific training.
The patch dissolves into the skin and could eliminate the use of hypodermic needles and the subsequent concerns about effective disposal.
It is thought that they could prove invaluable during pandemics and in large-scale immunisation programmes, especially in developing nations.
The microneedle arrays are made from poly-vinyl pyrrolidone, which is considered safe for use in the body.
