Delta Variant Produces Similar Viral Loads in Vaccinated, Unvaccinated: CDC Study

Washington: The Delta variant of COVID-19 produces similar amounts of virus in vaccinated and unvaccinated people if they get infected, showed a new study published by the US Centers for Disease Control and Prevention (CDC) on Friday. The CDC study focused on 469 COVID-19 cases identified among Massachusetts residents who had travelled to Barnstable County, a summer vacation destination, during July 3 to 17, the Xinhua news agency reported.

A total of 346 cases, about 74 per cent, occurred in fully vaccinated people, according to the study.

Testing identified the Delta variant in 90 per cent of specimens from 133 patients.

Cycle threshold values were similar among specimens from patients who were fully vaccinated and those who were not, according to the study.

The study demonstrated that Delta infection resulted in similarly high SARS-CoV-2 viral loads in vaccinated and unvaccinated people, said CDC Director Rochelle Walensky.

“High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with Delta can transmit the virus,” she said.

Walensky said that this finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation.

The CDC updated its masking recommendation on Tuesday, urging vaccinated Americans to resume wearing masks in schools and in public indoor spaces in Covid-19 hot spots across the country.

“The masking recommendation was updated to ensure the vaccinated public would not unknowingly transmit virus to others, including their unvaccinated or immunocompromised loved ones,” she said.

The CDC suggested jurisdictions to consider expanded prevention strategies, including universal masking in indoor public settings, particularly for large public gatherings that include travellers from many areas with differing levels of SARS-CoV-2 transmission.

‘Right Decision, Wise Decision and the Best Decision’: US President Biden as He Marks the End of War in Afghanistan

Washington: A day after the last American troops were pulled out of Afghanistan, United States President Joe Biden addressed the nation and defended his decision and said that ending the 20-year war was the best and the right decision for America. President Biden’s address came just 11 days ahead of the 20th anniversary of the 9/11, terrorist attacks that precipitated the US intervention in Afghanistan. During his address, Biden said there was no reason to continue in a war that was no longer in the service of the vital national interest of the American people. He said, “I give you my word: With all of my heart, I believe this is the right decision, a wise decision, and the best decision for America. The war in Afghanistan is now over.
