Data from the U.S. Centers for Disease Control and Prevention (CDC) Indicates that the Delta variant of COVID-19 is equally infectious whether it is infected by a vaccinated person or an unvaccinated person.
This means that both vaccinated and unvaccinated people can spread the virus to other people.The data comes from a confidential presentation released by CDC on Thursday Washington post.
Unvaccinated people and Delta variants are the main reasons for the recent increase in new COVID-19 cases across the country. When a vaccinated person becomes infected with COVID-19, it is called a “breakthrough” case because the virus has broken through the immunity provided by the vaccination.
The CDC presentation slide specifically mentions the equivalent infectivity of the variant, citing inspections of the recent outbreak in Barnstable County, Massachusetts.The focus of this slide is something called the Circulation Threshold (CT) value. This number indicates how many viruses are in the infected person’s body, according to science Magazine.
Among the 85 vaccinated and 65 unvaccinated people who were recently infected in Barnstable County, the CT values of the two groups were approximately the same. This means that once a Delta variant infects a person, their body will carry roughly the same amount of virus regardless of their vaccination status. This amount makes them equally capable of transmitting the virus to other people.

In addition to these data, the CDC’s slides also revealed the agency’s concern that breakthrough cases are undermining public confidence in the COVID-19 vaccine.
Some of the earliest slides of the presentation pointed out that breakthrough cases most often occur in crowded environments and high-risk groups, such as the elderly and people with weakened immune systems. A slide also emphasized the importance of communicating how often breakthrough cases actually occurred.
A symptomatic breakthrough infection appears to occur in 0.0098% of all fully vaccinated people. ABC The CDC reported a news study of the case last week. The CDC reports that, in other words, of the 156 million fully vaccinated Americans, 153,000 were infected with symptomatic COVID last week.
However, these numbers may be lower than the actual number of breakthrough infections. The COVID-19 detection rate has dropped, and the CDC has stopped keeping data on asymptomatic or mild breakthrough cases, which means that the exact number of breakthrough cases is difficult to count.
The CDC’s presentation also includes a bar chart showing that people who are vaccinated are eight times more likely to be infected with COVID-19 than people who have not been vaccinated. Vaccinated people are also 25 times less likely to be hospitalized or die from the coronavirus.
Nevertheless, the report also pointed out that these vaccines are not as effective as against the original COVID-19 strain in preventing Delta variants. Therefore, the Delta variant makes it more difficult to reduce new infections, especially since only 56% of Americans over the age of 12 are fully vaccinated.
A CDC slide stated that health officials need to acknowledge that “the war has changed.” “Given the higher transmission rate… Universal shielding is essential to reduce the spread of Delta variants.”
The slide also emphasizes the need for mandatory vaccination by healthcare providers and the need for other non-medical interventions to help prevent future outbreaks.
