In advance of the 2021 Copa América in Uruguay, Messi donated three signed shirts to the Chinese pharmaceutical firm Sinovac Biotech—whose directors spoke of their admiration for Messi—in order to secure 50,000 doses of Sinovac's COVID-19 vaccine, CoronaVac, in the hope of vaccinating all of South America's football players. A deal brokered by Uruguay's president Luis Lacalle Pou, the plan to prioritise football players caused some controversy given widespread vaccine scarcity in the region, with the Mayor of Canelones in Uruguay remarking that "Just as the president manifested cooperation with CONMEBOL to vaccinate for the Copa América, he could just as well have the same consideration for Canelones".
