As the country experiences a surge in COVID-19 cases, so has University of California, Irvine, which is also boasting a vaccination and booster rate of 98%. That’s as high as can be expected, many at the front of the coronavirus response believe. In recent days, the campus has seen a surge in cases anyway, a reminder that no matter the caution and preparation an institution may make, spikes can happen anyway. … David Souleles, [director of the COVID-19 Response Team], who took over the COVID-19 response for the university just as the illness began to spread, said he expects numbers to drop after graduation next week. But what comes after that is impossible to say.
