The Biden administration is reversing a Trump-era policy that barred undocumented college students and others from receiving federal relief grants meant to help pay for expenses like food, housing, and child care during the coronavirus pandemic.

The world may need to learn to live with the virus.

Early in the pandemic, there was hope that the world would one day achieve herd immunity, the point when the coronavirus lacks enough hosts to spread easily. But over a year later, the virus is crushing India with a fearsome second wave and surging in countries from Asia to Latin America.

Experts now say it is changing too quickly, new more contagious variants are spreading too easily and vaccinations are happening too slowly for herd immunity to be within reach anytime soon.

That means if the virus continues to run rampant through much of the world, it is well on its way to becoming endemic, an ever-present threat.
