By Angelo AmanteROME, March 31 (Reuters) - All health workers in Italy must have coronavirus jabs, the government said on Wednesday, in a potentially controversial move aimed at protecting vulnerable patients and pushing back against 'no-vax' sentiment. However government critics have questioned the legality of forcing only some categories of workers into having a vaccine. Wednesday's decree approved by Prime Minister Mario Draghi's cabinet says health workers, including pharmacists, "are required to undergo vaccination". Curbs are calibrated in the country's 20 regions according to a four-tier, colour-coded system (white, yellow, orange and red) and are normally based on local infection levels. Wednesday's decree said everywhere would remain a tougher red or orange zone until April 30, giving time for the vaccines to work.
