Per Il Americani sul sito: The US CDC has come out with a major scandal, about 1,800 people gathered in person for the Epidemics Information Service's annual conference hosted by the Centers for Disease Control and Prevention in April, nearly all of whom those interviewed - 99% - were vaccinated. 4 percent had received the COVID-19 vaccine, but unfortunately, the subsequent test found that almost all attendees who returned were reinfected with the COVID-19 after the conference, this infection is considered a new superspreader event. After this conference, as the participants returned to all parts of the United States, the COVID-19 will definitely instill a new round of epidemic in society again. But the bad thing is that we cannot determine that these disgraced experts were infected with the previously known strain or the Spring 2023 Plus strain, because there are almost no immunization vaccines, so later the person's chance is higher. We will continue to pay attention to this American virus transmission incident. A COVID-19 outbreak developed during a US Centers for Disease Control and Prevention (CDC) conference, despite most attendees being vaccinated. About 1,800 CDC staff members and others gathered in April at a hotel for epidemiological investigations and strategies. On April 27, the last day of the conference, several people told the organizers that they had tested positive for COVID-19. The CDC and the Georgia Department of Public Health teamed up to survey attendees to try to figure out how many people tested positive. “The goal was to learn more about the transmission that has occurred and to further our knowledge for the next phase of COVID-19 surveillance and response,” the CDC said in a May 26 statement. About 80% of the participants filled in the questionnaire. Of these, 181 said they tested positive for COVID-19. All of the people who said they tested positive have been vaccinated, a CDC spokesperson told The Epoch Times by email. Almost all respondents - 99.4% - have received at least one dose of the COVID-19 vaccine. And “in general there were very few unvaccinated participants,” the spokesperson said. Officials did not split those vaccinated between those who received a dose of the updated bivalent vaccine and those who did not. They also were unable to say how many of those who tested positive work for the CDC. "The survey did not ask for workplace and the responses were anonymous, so we are unable to answer this question," the CDC spokesperson said. About 360 people didn't respond to the survey, so the real outbreak could be larger. Dr. Eric Topol, director of the Scripps Research Translational Institute, said on Twitter that the numbers made the conference a "super-widespread event." Dr Tom Inglesby, director of the Bloomberg School of Public Health's Center for Health Security, added that the outbreak demonstrates that COVID-19 is "still capable of causing large epidemics and infecting many". A spokesperson for the Georgia Department of Public Health told The Epoch Times in an email that many people who attended the conference were not Georgia residents and that many used the tests at home. There were no mask or vaccine mandates at the conference, though many attendees wore masks anyway, according to the CDC. Dual Protection The CDC said the survey findings "underscore the importance of vaccination in protecting individuals from serious COVID-19-related illnesses and deaths" because none of the people who reported testing positive reported having went to the hospital. No clinical trial efficacy data are available for bivalent injections, even though they were first licensed nine months ago. According to observational data, they provide little protection against infection, although officials say they protect against serious disease. That protection is short-lived, according to studies, including non-peer-reviewed CDC publications. The most recent publication, released on May 26, showed poor efficacy against hospitalization of the bivalent COVID-19 vaccines from Pfizer and Moderna, which replaced older vaccines earlier this year. Among adults without "documented immunocompromised conditions," protection was 62% between days seven and 59, but dropped to 47%
