Sen. Bernie Sanders repeated calls for pharmaceutical companies to relinquish intellectual property rights to COVID-19 vaccines.
If companies like Pfizer and Moderna relinquished IP rights, their vaccines could be produced globally.
But the companies have opposed these calls, claiming risks to vaccine safety.
"But not only do we have a moral responsibility to help the rest of the world, it's in our own self-interest.
Sanders, an Independent, also weighed in on the debate over whether US pharmaceutical companies should relinquish their intellectual property rights to allow other companies across the world to produce vaccines.
Pharmaceutical companies, including Pfizer, Moderna, and Johnson & Johnson, and the US Chamber of Commerce have opposed such calls.
More than 80 WHO members have backed a proposal by India and South Africa to temporarily wave the IP rights of the companies. »
