COVID-19 vaccine mandates moving the needle, experts say

The efforts of early workplace vaccine mandates have been successful so far for companies and public offices large and small.

Vaccine mandates have been yet another controversial move in the deeply divisive COVID-19 pandemic, sparking lawsuits, protests and warnings of reductions in service.

But data and experts suggest that they are working.

In fact, some organizations saw their employee vaccination rates jump from less than half to over 90%.

James Colgrove, a professor of public health at Columbia University's Mailman School of Public Health told ABC News that he's not surprised with this outcome and predicted that similar workplace orders will follow the same story.
