No. The U.S has at large focused on itself first and foremost as it's allowed itself to become the most impacted nation by the pandemic thus far. It hardly produces the medical tech and equipment it needs as it outsourced it's industry to cheaper countries, like China. Additionally, capitalists holds the vaccine formulas hostage in exchange for an exorbitant cost. Poor countries would have to sell themselves once again into bondage just tiny shipments of the vaccine should they not be lucky enough to purchase the license to produce it.

Contrasted with China's efforts to mass-produce medical supplies for global usage and the vaccines that have been made by them is already being distributed globally as well. Their efficiency has simply slid them from providing viral immunity to being viral prophylactics, which helps slow down the spread of the virus significantly from it's previously unchecked pace.

This is still weighted heavily in China's favor from my perspective.
