professor david speigelhalter — the winton professor of the public understanding of risk at cambridge universitya tuesday, the number of deaths is much higher than the real number of deaths that happened, say, yesterday, because we're doing some catch up with the lack of reports over the weekend. so, myjudgment would be that there is now less than 200 covid deaths happening per day, which is extraordinary given that it was 1,200 a dayjust six weeks ago. and that reflects the latest data for the office of national statistics, showing the big reduction in deaths, and it is, i mean, we must have known, hoped these vaccines would work, but it is quite extraordinary that the death rates in the vaccinated groups, the over 65s, they are halving in a week, just a bit over a week, so they really are coming right down. in other words, does that mean that the vaccine roll—out in terms of its successes exceeded expectations, would you say, or certainly exceeded your expectations? i think they have exceeded everyone's expectations. i mean, its multiple things, first of all, the success of the roll—out, the f

that's according to new research from the university of cambridge, which suggests an average drop of health correspondent anna collinson reports. obesity is seen as one of the biggest health crises facing the uk. to try and tackle the problem, three years ago, the government brought in a tax to discourage customers, particularly children, from buying the most sugary drinks. if a beverage contains more than five grams of sugar per 100 millimetres, companies have to pay a levy. if it's below that, they don't. now, a study suggests that in the year since this was introduced, there was no change in the total volume of soft drinks bought, but there was a reduction in the amount of sugar consumed, an estimated three teaspoons per person, perweek. researchers believe it's because manufacturers have increased healthier options by changing the formulas for their products, reducing sugar content. it's notjust helping people to have healthier diets to consume less sugar, but the fact that we found no change in the total volume of drinks purchased suggests to us that this is good news for indust
