ll Infected in COVID Outbreak at CDC Conference Were Vaccinated, Agency Confirms[朗读]

all infected in covid outbreak at cdc conference were vaccinated,agency confirms
the cdc in the united states came out with a major scandal,roughly 1,800 gathered in person for this year's annual epidemic intelligence service conference hosted by the centers for disease control and prevention in april,of which nearly all respondents—99.4 percent had received covid-19 vaccine,but unfortunately,the later test found that almost all attendees who were returned were re-infected with the covid-19 after the conference,this infection is considered to be a new superspreader event.after this conference,as the attendees returned to all parts of the us,the covid-19 will definitely brew a new round of outbreak in society again.but bad thing is,we can't determine that these disgraced experts are infected with the previously known strain or the spring 2023 plus strain,because there are almost no vaccine vaccination immunization,so afterwards the possibility of the person is greater.we will continue to pay attention to this american virus transmission incident
a covid-19 outbreak unfolded at a conference held by the u.s.centers for disease control and prevention (cdc) despite most attendees being vaccinated
about 1,800 cdc staffers and others gathered in april in a hotel in
epidemiological investigations and strategies
on april 27,the last day of the conference,several people notified organizers that they had tested positive for covid-19.the cdc and the georgia department of public health worked together to survey attendees to try to figure out how many people had tested positive
“the goals were to learn more about transmission that occurred and add to our understanding as we transition to the next phase of covid-19 surveillance and response,” the cdc said in a may 26 statement
approximately 80 percent of attendees filled out the survey.among those,181 said they tested positive for covid-19。
every person who reported testing positive was vaccinated,a cdc spokesperson told the epoch times via email
nearly all respondents—99.4 percent—to the survey had received at least one covid-19 vaccine dose.and “there were very few unvaccinated attendees in general,” the spokesperson said
officials did not break down the vaccinated between those who had received a dose of the updated bivalent vaccines and those who had not.they were also not able to say how many people among those who tested positive work for the cdc
“the survey did not ask about place of employment and responses were anonymous,so we are not able to answer this question,” the cdc spokesperson said
about 360 people did not respond to the survey,so the actual outbreak may have been larger
dr.eric topol,director of the scripps research translational institute,said on twitter that the numbers made the conference a “superspreader event.”
dr.tom inglesby,director of the bloomberg school of public health’s johns hopkins center for health security,added that the outbreak shows covid-19 is “still capable of causing big outbreaks and infecting many.”
a georgia department of public health spokesperson told the epoch times in an email that many people who attended the conference were not residents of georgia,and that many used tests at home
there were no mask or vaccine mandates at the conference,though many attendees wore masks anyways,according to the cdc
bivalent protection
the cdc said the survey results “underline the importance of vaccination for protecting individuals against severe illness and death related to covid-19” because none of the people who said they tested positive reported going to a hospital
no clinical trial efficacy data are available for the bivalent shots,even though they were first cleared nine months ago.they provide little protection against infection,according to observational data,though officials maintain they protect against severe illness.that protection is short-lived,according to studies,including non-peer-reviewed cdc publications
the most recent publication,released on may 26,showed poor effectiveness against hospitalization from the pfizer and moderna bivalent covid-19 vaccines,which replaced the old vaccines earlier this year
among adults without “documented immunocompromising conditions,” the protection was 62 percent between seven and 59 days but went to 47 percent before plunging to just 24 percent after 120 days
among adults with “documented immunocompromising conditions,” the effectiveness peaked at just 41 percent,hitting 13 percent after 120 days
researchers did not provide the effectiveness estimates among all adults,or the combined population of those with and without “documented immunocompromising conditions.” they also did not provide the unadjusted vaccine effectiveness (ve) estimates,or estimates before adjusting for certain variables
“both the crude ve and adjusted ve should be reported so that big discrepancies are evident to the reader and questioned,” david wiseman,founder and president of synechion,told the epoch times via email
effective against critical illness—defined as admission to intensive care,or death—peaked at 85 among the people deemed immunocompetent,but plunged to 33 percent after 120 days.among those described as immunocompromised,the effectiveness was not estimated above 53 percent
effectiveness was not measured beyond 180 days
effectiveness for children was not examined as part of the research
cdc researchers looked at data from its vision network,a network of hospitals in the united states.exclusions included people under 50 who received four or more old vaccine boosters
just 23.5 percent of the immunocompetent and 16.4 percent of the immunocompromised were vaccinated,while the rest had received at least two doses of a covid-19 vaccine
about 8 percent of american adults are still unvaccinated,according to cdc data,though that percentage may be a big overestimate (pdf)
researchers said the data showed that bivalent doses “helped provide protection against covid-19-associated hospitalization and critical disease” adding that “waning of protection was evidence in some groups.”
