Biden Administration Plans to Offer Updated Booster Shots in September – The New York Times

The Biden administration now expects to begin a Covid-19 booster campaign with retooled vaccines in September because Pfizer and Moderna have promised that they can deliver doses by then, according to people familiar with the deliberations.

With updated formulations apparently close at hand, federal officials have decided against expanding eligibility for second boosters of the existing vaccines this summer. The new versions are expected to perform better against the now-dominant Omicron subvariant BA.5, although the data available so far is still preliminary.
