— Leader berates North Korean officials for ‘crucial’ virus lapse — As COVID recedes in prisons, will any lessons learned stick? ___ ___ HERE’S WHAT ELSE IS HAPPENING: TUBINGEN, Germany — German vaccine maker CureVac says younger people could benefit from its coronavirus shot, following disappointing results two weeks ago in a broader age group. The company said Wednesday that its vaccine is 53% effective against COVID-19 of any severity in 18- to 60-year-olds. Overall, though, CurveVac says the shot is 48% effective, based on 83 cases in the vaccine group and 145 in the placebo group. The World Health Organization has said vaccines with an efficacy above 50% are worth using, though many of those already approved have a far higher rate.
