🚨⚠️«اظهارات نادرست در مورد ایمنی جمعی» ناشی از «تفسیر اشتباه از پیش‌ایمنی ناشی از سلول‌های تی در کووید-۱۹»
به‌عنوان نمونه‌ای از «تفسیر اشتباه از اطلاعات درست»
@nouritazeh

1⃣پروفسور شِین کروتی
Shane Crotty
و همکارانش دو مقاله منتشر کرده‌اند که در آن احتمال پیش‌ایمنی ناشی از سلول‌های تی در مقابل کووید-۱۹ مطرح شده.
برخی اشخاص از این مقاله نتیجه گرفته‌اند که این می‌تواند در ایجاد ایمنی جمعی نقش مؤثری داشته باشد.👈نمونه

«برخی» اشخاص از مقالات علمی چیزی را برداشت می‌کنند که نویسنده نخواسته و کم و بیش لطیفۀ 👈«ما به احترامش می‌پوشیم!» را یادآور می‌شوند‌؛
و گاهی یادآور ماجرای 👈«نمی‌ذارم قانون در بره!» می‌شوند.

انتشار گستردۀ اطلاعات نادرست که بخشی از آن‌ها ناشی از تفسیر اشتباه از اطلاعات درست است، دلایل مختلف و غالباً روشنی دارد؛
اما دلایلی هم کم‌تر مورد توجه قرار گرفته؛ از جمله این دلیل: 👈دستِ‌دوم‌خوانی

2⃣ حالا پروفسور کروتی در رشته توئیتی که متن کاملش در ادامه آمده است، توضیح می‌دهد که برداشتی که از مقالاتشان شده اشتباه است.

متن کامل رشته‌توئیت (مقالات مورد اشاره در متن، در ادامه):
✅✅ Shane Crotty:
There are various tweets 🔴misinterpreting COVID-19 “pre-existing immunity” and 🔴making dangerous claims about #herd_immunity.
Since many of those claims refer to our scientific papers, we will reiterate the facts.

Our 1st scientific paper showed that ~50% of 🔸unexposed people have T cells that recognized SARS-CoV-2 already
t.me/nouritazeh/3248.
The most obvious conclusion was these were memory T cells from previous 🔸common cold coronavirus infections, but that was not directly shown.

Our 2nd paper, very recently published, showed that these were memory T cells from previous common cold coronavirus infections
t.me/nouritazeh/3249.

Five other labs have also published related findings
t.me/nouritazeh/3250

These observations about pre-existing T cell immunity (also call "crossreactive immune memory", which avoids the word "immunity" that sometimes gets misinterpreted as “protective immunity” [sorry, immunology is complicated] ) are important because these memory cells MAY impact people’s responses to SARS-CoV-2 infection, or COVID-19 vaccines.

Therefore, we have pointed out that these coronavirus crossreactive immune memory T cells are important to pay attention to in human COVID-19 studies this year.

We SPECULATE that it is conceivable that these T cells may potentially reduce COVID-19 disease severity, based on things we know about flu and T cells.

These are only 🔴speculations (no data) and because of their potential importance it is key for scientists to test these ideas, as quickly as possible. While scientists are racing as fast as possible, sophisticated research like this usually takes a lot of time and resources.

We, and other labs, are working hard on these unanswered questions.
Additionally, even if our most optimistic speculations about crossreactive T cell memory were found to be correct, it would mean that just as many people would get infected with SARS-CoV-2, but fewer would become severely ill and die from COVID-19.

🔴T cells generally don’t completely prevent infections, they limit disease (make it shorter and/or less serious).
🔴Thus, wearing a #mask is much more effective than hoping you and the people around you have pre-existing T cell memory.
Wearing a mask stops infections.

For people who were asking for more information about masks, extensive data support that masks are one of the most effective interventions to reduce SARS-CoV-2 spread and COVID-19 cases:

One excellent new summary of the scientific and medical literature is:
t.me/nouritazeh/3244

Or if you prefer one study:
t.me/nouritazeh/3245

Or if you prefer 70 sources:
t.me/nouritazeh/3246

But if you prefer a visual aid summarizing the knowledge on masks and COVID-19, National Geographic has you covered:
t.me/nouritazeh/3247
