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.
