Anthony Fauci the nation’s top infectious disease expert, said on Thursday that “inevitably” everyone will need booster shots for the COVID-19 vaccine eventually because like any vaccine, its protection won’t be “indefinite.” NBC News’ Craig Melvin asked Fauci on “Today” whether it’s “inevitable” that “in the not too distant future everyone is going to need a booster shot,” as the debate over the necessity of third shots has ramped up. President Biden’s chief medical adviser at first emphasized that immunocompromised people “never really got a good response” from the vaccine to more robustly protect them from COVID-19.
