A patent-free vaccine for the world

We speak to Dr. Peter Hotez and Dr. Maria Elena Bottazzi about developing a patent-free COVID-19 vaccine, and how they hope it will help fight global vaccine inequality.

Texas-based scientists Maria Elena Bottazzi and Peter Hotez won't make a cent off the vaccine they developed — and they don't want to.

Dubbed "the world's COVID-19 vaccine," Corbevax is cheap and relatively easy to manufacture, and there's no patent on it. After multiple hurdles in the team's efforts to fund and develop the jab, Corbevax was recently approved for emergency use in India.

Today, we're speaking to Bottazzi and Hotez about the story behind Corbevax, what the skeptics have to say, and why they believe their shot can be a powerful tool in the fight for vaccine equity.
