MEXICO CITY -- Mexican President Andres Manuel Lopez Obrador said Tuesday that his country is doing better than the United States in dealing with the coronavirus pandemic, even though Mexico's per capita death rate is probably higher and the country has vaccinated less than 1% of its population.

Lopez Obrador said Tuesday that comparing countries is in "bad taste," but went on to say "the most powerful nation on earth, our neighbour, did worse than us."

The Mexican government's "estimated" death toll from COVID-19 is now about 201,000. The United States death toll is around 500,000, but its population is 2.6 times larger.

Moreover, estimates of excess deaths in Mexico since the start of the pandemic suggest the COVID-19 toll is now well above 220,000. Mexico has administered about 1.7 million vaccine doses, while the U.S. has given 64 million shots.

Lopez Obrador blamed rich countries for "hoarding" vaccines, calling that "totally unfair," and said "the UN has to intervene."

Lopez Obrador has demanded the United States vaccinate the millions of Mexicans living in the U.S. with or without legal documents; Mexico says its consulates in the United States have even been registered as vaccination centres.

But a photo circulated on social media showed a sign posted last week outside one Mexico City vaccination centre stating "No Foreigners Will be Vaccinated."

Presidential spokesman Jesus Ramirez said that was a mistake, and promised everyone over 60, foreigners and Mexicans alike, would have access to vaccines.

"That was a photo of one centre, and that message was corrected," Ramirez said.

But Dr. Ruy Lopez Ridaura, the country's director of disease prevention and control, said the exclusion of foreigners apparently occurred at other sites in the opening weeks of the vaccination effort.

"There may have been some confusion at some operating sites," Lopez Ridaura said. "It was a communication problem. ... The orders are totally clear now, foreigners will also receive their vaccinations."

Lopez Obrador invited Argentine President Alberto Fernandez onstage at his daily morning press conference Tuesday, and the Argentine leader proposed that vaccine companies be forced to cede intellectual property rights and allow anyone to manufacture their shots.

"The idea is to propose at the G20 the need to declare COVID-19 vaccines as `global goods,' so that they cede their intellectual property rights and all countries can freely produce them," Fernandez said.

Mexico is trying to beef up its supply of Pfizer vaccines with Russian and Chinese shots, and late Monday the country received its first shipment of 200,000 doses of the Russian Sputnik V vaccines.

Mexico has had over 2 million test-confirmed coronavirus cases, but the low level of testing means the real number is probably several times that amount.
