CAT WISE: Steve Davis is president and CEO of PATH. He says one of the organization\u2019s most successful products could come in handy in fighting the Ebola outbreak if a vaccine using a live virus, that has to be kept cold, is developed.<\/p>\n
It\u2019s a tiny heat-sensing sticker that tells health workers if a vaccine is no longer effective. It\u2019s been used on five billion vaccine vials over the past two decades.<\/p>\n
STEVE DAVIS: It turns out, in food, in frozen chicken, they have something on the package to show that if it had been thawed or unthawed. So we took that idea and now, by having a vaccine vial monitor, this little dot, we can actually tell whether that vaccine has got too hot, and therefore we wouldn\u2019t use it if it\u2019s changed colors.<\/p>\n
And so that\u2019s \u201d\u201d that\u2019s been really critical, saved literally millions of lives.<\/p>\n
