President Joe Biden’s commitment to donate 500 million COVID-19 vaccine doses (sufficient to fully vaccinate 250 million people) was great news. But with billions of people in desperate need and some countries not having any access to COVID-19 vaccines, America can and should do far more.

With the planet’s nearly 8 billion people needing 12 billion or more doses, providing 4% of that should only be the start of the historic contribution the United States can and should make. The reality is our current efforts are a proverbial “drop in the bucket” and are off by at least one order of magnitude. Just as critical, we are missing a historic opportunity for U.S. global leadership.
