Biden's chief of staff won't say when booster shots will be available but commits to following the science

White House chief of staff Ron Klain would not give a specific date as to when Covid-19 booster shots would be available to the public but committed to following the science and waiting for full approval from health officials before making a third dose available to those who seek one.

This comes after CNN and other outlets reported that top health officials warned the White House that they need more time to review all the necessary data before they can recommend boosters for all adults, despite an initial announcement last month that boosters for people who had either mRNA Covid-19 vaccine would be available the week of September 20. "I would be absolutely clear, no one's going to get boosters until the FDA says they're approved, until the CDC advisory committee makes a recommendation. What we want to do though is be ready as soon as that comes," Klain told CNN's Dana Bash on Sunday's "State of the Union."
