Amid a sometimes chaotic rollout of vaccines across the US, health experts say a glimmer of good news has emerged, with recent reports of cases in nursing homes having declined for the past four weeks, according to federal data.

Johnson & Johnson said Friday that its single-dose coronavirus vaccine was 72% effective in protecting against moderate and severe Covid-19 in the US, but was less potent in other regions.

New Covid-19 cases continue to trend downward, with 16% fewer cases reported this week than last, but 95% of the US population lives in a county that the federal government considers to be a “sustained hotspot," according to a report.

The Cybersecurity and Infrastructure Security Agency announced a series of teleconferences on COVID-19 and vaccine distribution.

More than 24.6 million doses of Covid-19 vaccine have been administered in the US, according to data published Wednesday by the US Centers for Disease Control and Prevention.

The Centers for Disease Control and Prevention reported today that nearly 20 million people have received at least one dose of the vaccine, and nearly 3.5 million people have been fully vaccinated.
