Slightly more than half of US workers favor Covid-19 vaccine mandates in their workplaces, new polling finds, although far fewer have seen such requirements implemented by their employers. A 55% majority of Americans who are employed full-time, part-time or are self-employed say they'd support their employer requiring all employees to be vaccinated against Covid-19, while 44% are opposed, according to an Axios/Ipsos survey released this week.
