Officials say some coverage over Delta variant has been misleading and focus should be on encouraging people to accept vaccines.
Even as the White House highlighted what it considers alarmism in reporting of the surge in cases of the Delta coronavirus variant across the US, reports in the same national media suggested vaccinations are increasing in hotspot areas.
On Friday, an unnamed senior Biden administration official told CNN the press was reporting misleadingly on federal data indicating the Delta variant spreads among vaccinated as well as unvaccinated people.
The official said a focus on â€œbreakthrough infectionsâ€ might lead to people being more hesitant to get vaccinated, and said the White House had asked news organisations to tone down coverage.
One NBC News story on new data from the federal Centers for Disease Control and Prevention (CDC) was first headlined â€œBreakthrough Covid cases: at least 125,000 fully vaccinated Americans have tested positiveâ€.
NBC changed the headline to â€œBreakthrough Covid cases: data shows how many vaccinated Americans have tested positiveâ€.
In an official release, the CDC recommended that fully vaccinated people should now wear a mask â€œin public indoor settings in areas of substantial or high transmissionâ€
It added that fully vaccinated people â€œmight choose to wear a mask regardless of the level of transmission, particularly if they are immunocompromised or at increased risk for severe disease from Covid-19, or if they have someone in their household who is immunocompromised, at increased risk of severe disease or not fully vaccinated.â€
