Delta, the brand new "variant" compromises existing vaccines 全新「Delta變種」讓一切疫苗無效？

CGG-CGG，不可能在自然界存的基因信標，在武漢肺炎病毒中出現
July 30, the US CDC released a statement with a report.  In the report, the authors confirmed that the persons, whether fully vaccinated or not,  transmit SARS-CoV-2 to others. The authors indicate that the Delta variation is something that is unlike the others.
To me, having a conspiracy, it is a brand new bio-weapon, spread in India, other than what originated in Wuhan 2019.

感染Delta變種的人，不管打過疫苗或為未打疫苗，有一樣高的SARS-CoV-2病毒量。這表示：Delta與其他變種不同，會讓大過疫苗的人在不知不覺中傳染他人。更表示：Delta變種是另外一種全新的東西。

美CDC：應把Delta當成新病毒    聯合 20210801

美國聯邦疾病防治中心（ＣＤＣ）七月卅日公布的報告警告，Delta變種病毒恐導致更嚴重病症，而且可能像水痘一樣容易傳染，呼籲官員必須坦承「疫情戰出現變化」，應該把Delta病毒當成新病毒看待。

這份研究調查麻州接種率最高郡、度假景點鱈魚角，在七月四日美國國慶周末後，當地至今已有逾九百人確診，其中約四分之三為接種完疫苗者；而這些突破性感染者中，約八成病患出現咳嗽、頭痛、喉嚨痛、肌肉痛和發燒等常見症狀。

卅日公布的麻州新冠肺炎爆發的研究細節，指出已接種疫苗但仍出現突破性感染者，攜帶的新冠病毒量跟未接種者一樣多，並建議已接種者在國內部分疫情升溫區室內應重新戴上口罩。

該研究因此指出，ＣＤＣ口罩令應擴及全國，甚至在熱點區戶外也應戴上口罩；這項發現恐顛覆以往對疫情擴散的想法，科學家本以為已接種疫苗者染疫後病毒量低，較不容易感染他人，但是新數據顯示，Delta變種病毒並非如此容易防堵。

這份文件疾呼ＣＤＣ必須改變傳遞給大眾的訊息，強調接種疫苗是最有效防範新冠變種病毒的辦法，而且因為Delta變種病毒傳染力高，必須把它當成新病毒來看待，因應速度也要更快。

ＣＤＣ一個簡報指出，老年人無論是否接種疫苗，感染Delta變種病毒後，比年輕人有更高出現重症和死亡的風險；另一項預測指出，在逾1億6300萬名接種完畢的美國人中，每周恐有3萬5000人會染疫且無症狀。

這份文件概述已接種者染疫人數增加，恐產生「溝通挑戰」；地方機構擔心新冠疫苗是否依舊有效，他們也擔心大眾會覺得疫苗不再有效或者不需施打追加劑疫苗。

ＣＤＣ文件與鱈魚角爆發疫情均凸顯ＣＤＣ面臨鼓勵民眾接種的巨大挑戰，ＣＤＣ也得坦承有可能發生突破性感染，雖然已接種的染疫者具傳染力，但並不常見；ＣＤＣ發言人拒絕評論這些文件。

白宮發言人尚皮耶卅日表示，「重點很簡單，我們得讓更多人打疫苗。」

ＣＤＣ文件指出，當局需要新的溝通策略，先前政府一再保證疫苗功效，但民眾聽到突破性感染後，可能會影響他們對疫苗的信心，且有遭政府背叛的感受。

以下是報告的摘要

Summary

What is already known about this topic?

Variants of SARS-CoV-2 continue to emerge. The B.1.617.2 (Delta) variant is highly transmissible.

What is added by this report?

In July 2021, following multiple large public events in a Barnstable County, Massachusetts, town, 469 COVID-19 cases were identified among Massachusetts residents who had traveled to the town during July 3–17; 346 (74%) occurred in fully vaccinated persons. Testing identified the Delta variant in 90% of specimens from 133 patients. Cycle threshold values were similar among specimens from patients who were fully vaccinated and those who were not.

Statement from CDC Director Rochelle P. Walensky, MD, MPH on Today’s MMWR

Media Statement

On July 27th, CDC updated its guidance for fully vaccinated people, recommending that everyone wear a mask in indoor public settings in areas of substantial and high transmission, regardless of vaccination status.  This decision was made with the data and science available to CDC at the time, including a valuable public health partnership resulting in rapid receipt and review of unpublished data.

Today, some of those data were published in CDC’s Morbidity and Mortality Weekly Report (MMWR), demonstrating that Delta infection resulted in similarly high SARS-CoV-2 viral loads in vaccinated and unvaccinated people. 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. This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation. The masking recommendation was updated to ensure the vaccinated public would not unknowingly transmit virus to others, including their unvaccinated or immunocompromised loved ones.  今天，其中一些數據發表在 CDC 的發病率和死亡率週報 (MMWR) 中，表明 Delta 感染導致接種和未接種疫苗的人群中同樣高的 SARS-CoV-2 病毒載量。 高病毒載量表明傳播風險增加，並引發了人們的擔憂，即與其他變種不同，感染了 Delta 的疫苗接種者可以傳播病毒。 這一發現令人擔憂，並且是導致 CDC 更新口罩建議的關鍵發現。 更新了掩蔽建議，以確保接種疫苗的公眾不會在不知不覺中將病毒傳播給他人，包括未接種疫苗或免疫功能低下的親人。

This outbreak investigation and the published report were a collaboration between the Commonwealth of Massachusetts Department of Public Health and CDC. I am grateful to the commonwealth for their collaboration and rigorous investigation. I would also like to humbly thank the residents of Barnstable County who leaned in to assist with the investigation through their swift participation in interviews by contact tracers, willingness to provide samples for testing, and adherence to safety protocols following notification of exposure.

This outbreak investigation is one of many CDC has been involved in across the country and data from those investigations will be rapidly shared with the public when available. The agency works every day to use the best available science and data to quickly and transparently inform the American public about threats to health.
