Long-Covid Concerns Help Fuel Biden Administration’s Broad Vaccine Booster Push – The Wall Street Journal

Emerging data indicating that a small percentage of vaccinated people develop long-term Covid-19 is helping drive the Biden administration’s push to roll out boosters broadly, according to people familiar with the planning.

Breakthrough infections among fully vaccinated people remain rare and long Covid cases are more common in unvaccinated people. Yet some federal health regulators see the new data as a reason to offer boosters more widely in the coming weeks, the people said. Other health experts, however, say most people don’t need the extra doses.
