Ковид-19 во Франции и в мире - 16

[IdaLou]

В Массачусетсе 21 июля было выявлено 469 случаев ковида. Из них - три четверти полностью вакцинированы:

vaccination coverage among eligible Massachusetts residents was 69%. Approximately three quarters (346; 74%) of cases occurred in fully vaccinated persons (those who had completed a 2-dose course of mRNA vaccine [Pfizer-BioNTech or Moderna] or had received a single dose of Janssen [Johnson & Johnson] vaccine ≥14 days before exposure). Genomic sequencing of specimens from 133 patients identified the B.1.617.2 (Delta) variant of SARS-CoV-2, the virus that causes COVID-19, in 119 (89%) and the Delta AY.3 sublineage in one (1%). Overall, 274 (79%) vaccinated patients with breakthrough infection were symptomatic. Among five COVID-19 patients who were hospitalized, four were fully vaccinated; no deaths were reported. Real-time reverse transcription–polymerase chain reaction (RT-PCR) cycle threshold (Ct) values in specimens from 127 vaccinated persons with breakthrough cases were similar to those from 84 persons who were unvaccinated, not fully vaccinated, or whose vaccination status was unknown (median = 22.77 and 21.54, respectively)."

И что? Вы статью читали? Или только заголовок? Обсуждение читали? (Обсуждение - это не комментарии в ФБ, твиттере, ю-тубе, а разбор случаев исследования по статистике, видам, возможности сделать или нет выводы из данного исследования).

The findings in this report are subject to at least four limitations. First, data from this report are insufficient to draw conclusions about the effectiveness of COVID-19 vaccines against SARS-CoV-2, including the Delta variant, during this outbreak. As population-level vaccination coverage increases, vaccinated persons are likely to represent a larger proportion of COVID-19 cases. Second, asymptomatic breakthrough infections might be underrepresented because of detection bias. Third, demographics of cases likely reflect those of attendees at the public gatherings, as events were marketed to adult male participants; further study is underway to identify other population characteristics among cases, such as additional demographic characteristics and underlying health conditions including immunocompromising conditions.*** MA DPH, CDC, and affected jurisdictions are collaborating in this response; MA DPH is conducting additional case investigations, obtaining samples for genomic sequencing, and linking case information with laboratory data and vaccination history. Finally, Ct values obtained with SARS-CoV-2 qualitative RT-PCR diagnostic tests might provide a crude correlation to the amount of virus present in a sample and can also be affected by factors other than viral load.††† Although the assay used in this investigation was not validated to provide quantitative results, there was no significant difference between the Ct values of samples collected from breakthrough cases and the other cases. This might mean that the viral load of vaccinated and unvaccinated persons infected with SARS-CoV-2 is also similar. However, microbiological studies are required to confirm these findings.

Event organizers and local health jurisdictions should continually assess the need for additional measures, including limiting capacity at gatherings or event postponement, based on current rates of COVID-19 transmission, population vaccination coverage, and other factors.§§§ On July 27, CDC released recommendations that all persons, including those who are fully vaccinated, should wear masks in indoor public settings in areas where COVID-19 transmission is high or substantial. Findings from this investigation suggest that even jurisdictions without substantial or high COVID-19 transmission might consider expanding prevention strategies, including masking in indoor public settings regardless of vaccination status, given the potential risk of infection during attendance at large public gatherings that include travelers from many areas with differing levels of transmission.

А к чему вы IdaLou процитировали, к дождю?.. вы уверены, что смогли прочитать поняли смысл своей статьи? Там говорится, что одинаково заражаются как привитые, так и непривитые, поэтому организаторам мероприятий в крытых помещениях рекомендуется, чтобы участники носили маски, как вакцинированные, так и нет. То есть вы подтверждаете то, что пишет IdaLou, но почему-то пишете «и что?».

Baila-baila, спасибо. Вот приносишь что-то и всегда сторонникам обязательной вакцинации что-то не так: то источник, то интерпретация, то ещё что-то найдётся.

А за что Вы бвйлу благодарите? За то, что она Вам перевела отрывок из обсуждения? Я Вам именно поэтому и привела его, чтобы объяснить Вам из Вашей собственной ссылки о вакцинации, о мерах защиты, о возникновении кластеров. Смысл статьи в этом, а не в том, что 1/3 позитивных была вакцинирована 2 дозами Пфайзера или 1 дозой J&J.
Что нового в этой статье? Для полноты картины принесите ещё ссылки на исследования в Пенсильвании, Британской Колумбии, Гренландии, во всеми здесь любимыми Швеции и Швейцарии.
