A vaccine mandate for domestic travel may not happen, according to Dr. Anthony Fauci, the country’s top infectious disease expert, speaking to CNN this week. He had previously expressed support for a mandate but told CNN,  “I don’t think people should expect that we’re going to have a requirement in domestic flights for people to be vaccinated.” Last week, Dr. Fauci said on MSNBC that making the COVID-19 vaccine a requirement for domestic flights should be “seriously considered.” He said at that time: “If you're making a requirement for vaccination for people to get on planes who are coming into the country, that’s understandable. You don’t want to bring more cases into the country.“ But, he added, “If you’re talking about requiring vaccination to get on a plane domestically, that is just another one of the requirements that I think is reasonable to consider.” Meanwhile, Sara Nelson, president of the Association of Flight Attendants, raised some concerns about the recent CDC shift in policy, now requiring shorter isolation periods for employees who have been infected with COVID-19, shortening that period from 10 days to five days for those who are asymptomatic but requiring mask wearing for an additional five days. She said in a statement, “If any business pressures a worker to return to work before they feel better we will make clear it is an unsafe work environment, which will cause a much greater disruption than any ‘staffing shortages.’ “ She continued, “We cannot allow pandemic fatigue to lead to decisions that extend the life of the pandemic or put policies on the backs of workers.”
