after people get the third immunisation, if they are more than a couple of months out from the third immunisation, we are seeing a fair bit of breakthrough symptomatic illness from the 0micron variant, not so much to get them sick enough to land into hospital but enough to knock out the health care workforce, so they have to stay at home, and i think that's the third piece to this, delta, number one, 0micron surge number two, and an already depleted health care workforce now going to have to have a lot of absences, which will add to the stress of our already stressed health care system, so a lot to worry about. let's get some of the day's other news. the world health organisation has issued the emergency approval of a new coronavirus vaccine in india. covovax has been produced by the serum institute of india. it's part of the covax portfolio, an initative to vaccinate more people in lower—income countries.
