Vaccine hesitancy at home and exporting vaccines abroad: Dr. Anthony Fauci

When America's top infectious diseases expert, Dr. Anthony Fauci, was last on GZERO World in the fall of 2019, just weeks before the pandemic hit, he saw the country's the anti-vax movement as concerning, but still a fringe issue. What a difference a year makes, with one in five Americans saying today that they're reluctant to take the COVID-10 vaccine. Why has vaccine hesitancy grown so much?

One the many reasons Fauci offers: "One of the most common is they say, 'Well, it was so fast.' We always talk about vaccines requiring years to develop...And when we explain to people that this is just a reflection of the exquisite advances in the science of vaccine platform technology and immunogen technology...we can win more people over than you can imagine." Dr. Fauci also tackles the question of when, and how, to start exporting vaccines abroad.
