LONDON, Dec 14 —The former head of Britain’s vaccine task force said today that the vaccines against Covid-19 would need to become cheaper to administer - whether with patches, pills or sprays - to ensure countries do not have to spend so much.

"We can’t be in a position where we have to go through this monumental logistics challenge of actually getting vaccines into arms,” Kate Bingham, former chair of the UK Vaccine Taskforce, told a parliamentary committee.

"So the other area that I think we must be pushing forward is: how do we improve the format of these vaccines so that they are much easier and more cheap to deploy whether that is patches, pills or sprays.” — Reuters
