The global eradication of smallpox in 1980 is one of international public health's greatest successes. But in 1966, seven years after the World Health Organization announced a plan to rid the world of the disease, smallpox was still widespread. The culprits? A lack of funds, personnel and vaccine supply.

Meanwhile, outbreaks across South America, Africa, and Asia continued, as the highly contagious virus continued to kill three out of every 10 people who caught it, while leaving many survivors disfigured. It took a renewed commitment of resources from wealthy nations to fulfill the promise made in 1959.

Forty-one years later, although we face a different virus, the potential for vast destruction is just as great, and the challenges of funding, personnel and supply are still with us, along with last-mile distribution. Today, while 30% of the U.S. population is fully vaccinated, with numbers rising every day, there is an overwhelming gap between wealthy countries and the rest of the world. It's becoming evident that the impact on the countries getting left behind will eventually boomerang back to affect us all.

The international nonprofit CARE recently released a policy paper that lays out the case for U.S. investment in a worldwide vaccination campaign. Founded 75 years ago, CARE works in over 100 countries and reaches more than 90 million people around the world through multiple humanitarian aid programs. Of note is the organization's worldwide reputation for its unshakeable commitment to the dignity of people; they're known for working hand-in-hand with communities and hold themselves to a high standard of accountability.

"As we enter into our second year of living with COVID-19, it has become painfully clear that the safety of any person depends on the global community's ability to protect every person," says Michelle Nunn, CARE USA's president and CEO. "While wealthy nations have begun inoculating their populations, new devastatingly lethal variants of the virus continue to emerge in countries like India, South Africa and Brazil. If vaccinations don't effectively reach lower-income countries now, the long-term impact of COVID-19 will be catastrophic."
