MSNBC host Stephanie Ruhle spoke out on Thursday to claim that she does not understand people who are against vaccine passports.

“It is not just Disney,” Ruhle said. “Corporations, big and small, across the country are stepping up in a big way. 30 health care leaders from the last four administrations are out with a brand new letter this morning urging more CEOs to take steps to protect workplaces. They want vaccine requirements. If a company cannot, they’re asking them to take steps, adding incentives for vaccines, increased testing. Companies are saying they’re on board and are joining a huge list of companies following the letter’s guidelines.”

“Andy, if these guidelines become a trend, businesses can boost nationwide vaccines by 10%,” she added. “That is huge. Put it in context for us. How much will that stop the spread?”

Former White House senior COVID-19 adviser Andy Slavitt responded buy saying, “I think if businesses step up, people have said, 25 million people have said in order to go to work, go into large venues where they’re around other people, they need to be vaccinated, they would gladly get vaccinated. They’re just not prioritizing it.”

“That could bring us, Stephanie, from 70% to 80% of adults vaccinated,” he continued. “That would make an enormous difference on the path, dramatically reduce cases and deaths and provide the momentum we need.”

“I don’t understand those who are against showing proof of vaccine,” Ruhle said. “Have they never had to show their passport, show their ID, or take their kids to school? It makes no sense to me.”

Earlier this week, Slavitt talked about how important he feels it is to get people vaccinated.

“Delta has moved the needle on what we need to get done, we need to get many more people vaccinated,” Slavitt said.  “If you needed 70 to 80 per cent of the population vaccinated before, you need 80 to 90 per cent vaccinated now in order to keep the prevalence of the disease at a low level in the community.”
