Could Covid be eradicated?

Only one infectious disease, smallpox, has ever been eradicated, and that was after two centuries of inoculation and a concerted, 14-year campaign of global vaccination in the 1960s and ’70s. SARS-CoV-2, the virus that causes Covid, has proved to mutate rapidly, so epidemiologists say it is hard to predict how long immunity from prior infections and vaccinations will last. Booster shots may be necessary. In a survey by the magazine Nature, nearly 90 percent of immunologists, infectious-disease researchers, and virologists believe the disease will become endemic and circulate in pockets of the global population for the foreseeable future.
