While some countries are on an individual path out of the coronavirus pandemic thanks to their vaccination drives, that's not the norm. In fact, the world is coming off its worst ever week for COVID-19 infections, Bloomberg reports.

India and Brazil, two of the world's most populous nations, are both experiencing surges, which is contributing to the record-breaking numbers.

Analysts have warned for some time that unequal vaccine distribution would lead to these types of discrepancies. Bloomberg's David Fickling argues that the increase in cases is reflecting the varying trends around the world, though he clarifies that it actually appears to be middle-income countries, in which about two-thirds of the world's population resides, that are really falling behind on vaccinations.

Higher-income countries, like the United States, tend to have a surplus of doses, while low-income countries are receiving a significant amount on a per capita basis, as well, thanks to concentrated efforts like the COVAX, a global bulk-buying vaccine program. But the middle-income countries, including India and China, have low coverage area rates, suggesting it will still be some time before vaccinations tick up, which means the pandemic is likely far from over.
