wales Shielding in Wales has been extended until the end of March PEOPLE who are classed as extremely clinically vulnerable will be asked to shield until the end of March, the first minister has confirmed. While announcing the results of the latest review into alert level four measures in Wales, Mark Drakeford said that although there has been a "steady fall" in cases, it was still too early to start lifting restrictions. "We’ve fallen back from the peak of more than 600 cases per 100,000 people to 175 cases [per 100,000 people] today," he said.
