Fauci Cites Possible Delay for Moderna Booster

Anthony Fauci said U.S. booster shots against Covid-19 are likely to start only with the vaccine by Pfizer Inc. and BioNTech SE, while the Moderna Inc. shot may be delayed. White House Chief of Staff Ron Klain pushed back against criticism that the Biden administration is rushing booster shots ahead of scientific evidence. The Group of 20 are set to pledge to do more to tackle the impact of the pandemic on mental health as ministers meet in Rome this weekend.
