In 2020, he signed the UNAIDS Public Letter on People's Vaccine which was a campaign calling for accessibility of the COVID-19 vaccine to all. He joined other world leaders in the signing. He wrote "all people everywhere must have access to the vaccine when one becomes available." Concerns were raised that people in richer countries may have quicker access to the vaccine than poor countries which led to the writing of an open letter that any vaccine against the disease should be free and made available at no cost to all people. In February 2021, Ghana became the first African country to receive Covid-19 vaccines through the World Health Organization's COVAX program. The shipment, consisted of 600,000 doses of the AstraZeneca vaccines.
