Anthony Fauci had no reservations about a vaccine mandate for air travel on Sept. 11.

“I would support that if you want to get on a plane and travel with other people that you should be vaccinated,” the White House chief medical advisor said in the “Skimm This” podcast show according to The Hill.

President Joe Biden announced a new six-part strategy that aims to immunize millions more Americans against COVID-19. In recent months he become increasingly aggressive with administering jabs, especially after nearly 100,000 new infections were recorded daily.

However, his far-reaching plan does not include air travel. U.S. Surgeon General Vivek Murthy suggested making emergency flights possible for unvaccinated people. Federal law requires all airplane, bus, and train passengers to wear a face mask until at least Jan. 18, 2022.

When asked about vaccine requirements for school children, Fauci was open to the concept.

“When you hear us say should you mandate vaccination for children to be able to attend school, some people say, ‘Oh, my goodness. That would be terrible to do that,'” he said according to the paper. “But we already do that and have been doing that for decades and decades.”

“I do not know what school you went to but the school that I went to, you had to be vaccinated for measles, mumps, rubella, polio–or otherwise you could not go to school,” he added.

The experimental vaccines cannot guarantee full protection against COVID-19 infection or prevent the Delta variant from spreading. They are touted to reduce the risk of death and severe illness from the virus.

The shots have faced widespread hesitance due to growing concerns about rushed research and a lack of protection from potentially dangerous side-effects. The booster shot was only recommended after more data was available to prove previous doses wear off after just six months.

Messenger ribonucleic acid (mRNA) vaccines are also known to cause blood clots and heart inflammation in a relatively low percentage of recipients. An arguably low number of deaths have also been reported as adverse reactions.
