Patch to protect against measles shows promise
By Philippa Roxby
A vaccine patch could be a safe and effective alternative way to protect young children against measles, a trial in The Gambia suggests.
The device – the size of a sticking plaster – is easier to transport and store than standard injections, especially in remote areas.
Measles is a very contagious disease which is common in children, and can kill.
Protecting vulnerable children worldwide is a priority, experts say.
Despite the existence of a very effective measles jab, falling vaccination levels since the Covid pandemic have left millions of children unprotected, particularly in low- and middle-income countries.
But now, scientists hope microneedle-patch technology can put vaccinations back on track with 95% of children immunised.
The microarray patch sticks to the arm and lots of microscopic needles deliver the vaccine through the skin, with no pain.
