The shift to the pandemic’s vaccination phase has prompted many people to dwell at the micro level: When will I be fully vaccinated? When will my family and friends get their shots? When can we all revert to something resembling normal life? But that has lent a false sense of security to the vaccinated and obscured the perils lurking at the macro level, as devastating new waves of COVID-19 crash over countries such as India and Brazil and spread more transmissible variants of the virus beyond their shores.

“The United States may be advancing remarkably [with] the pace of vaccination, but so long as you have uncontrolled pandemics throughout the world, every contagion increases the likelihood of an ‘escape variant’ that eventually, with the level of interconnectedness we have, will find its way even [to] populations that have been vaccinated,” Julio Frenk, a former Mexican health minister and World Health Organization official, told me. “No one is safe until everyone is safe.” [..]

“The more contagion you have, the higher the likelihood that you will have a mutation and that that mutation will lead to a more contagious variant. And that’s exactly what’s happened,” said Frenk, now the president of the University of Miami. […]

Pedro Hallal, the lead investigator for EPICOVID-19, the largest epidemiological study of COVID-19 in Brazil, told me that he’s concerned about new variants popping up in Brazil that could, for example, be more dangerous for children or undermine the effectiveness of existing vaccines. Brazil, he said, has become a “variants factory.” […]

At its current sluggish pace, Brazil will take another 12 months to vaccinate 75 percent of its population.
