The United States administered 351,400,930 doses of Covid-19 vaccines in the country as of the morning of Aug. 8 and distributed 407,561,705 doses, the U.S. Centers for Disease Control and Prevention said.

The continued spread of the SARS-CoV-2 virus has spawned a Greek alphabet of variants – a naming system used by the World Health Organization to track concerning new mutations of the virus that causes Covid-19. Some have equipped the virus with better ways of infecting humans or evading vaccine protection.

One out of two Americans were fully vaccinated against Covid-19 as of Aug. 6, according to the U.S. Centers for Disease Control and Prevention.

There are early signs that people who have been vaccinated against Covid-19 may be able to transmit the Delta variant of the virus as easily as those who have not, scientists at Public Health England (PHE) said on Aug. 6.

With a new wave of Covid-19 infections fueled by the Delta variant striking countries worldwide, disease experts are scrambling to learn whether the latest version of coronavirus is making people – mainly the unvaccinated – sicker than before.

The world is at risk of losing hard-won gains in fighting Covid-19 as the highly transmissible Delta variant spreads, but WHO-approved vaccines remain effective, the World Health Organization said on July 30.

Americans fully vaccinated against Covid-19 should go back to wearing masks in indoor public places in regions where the coronavirus is spreading rapidly, U.S. health authorities said on July 27.

The U.S. Centers for Disease Control and Prevention is set on July 27 to recommend fully vaccinated Americans wear masks indoors in at least some instances, as the more highly transmissible Delta variant of the coronavirus has led to a surge in infections, sources said.

Despite reports of a rare neurological disorder appearing in some people who have received Johnson & Johnson’s Covid-19 vaccine, the benefits of its use outweigh the risks, a U.S. Centers for Disease Control and Prevention advisory panel said on July 22.

The model for healthcare delivery and treatment was upended by the COVID-19 pandemic, as ordinary Americans have learned to take more control of their own care and treatment, harnessing a new class of technology tools that have given individuals unprecedented clout. But patients and healthcare providers still need to partner together for the best outcomes, according to Jim Weiss, founder and CEO of Real Chemistry.
