殺し屋T コロナ抗体検査はあてにならない

 

 

The body should produce both protective antibodies, which keep the virus from invading, and killer T cells, which tell virus-infected human cells to destroy themselves to keep the virus from spreading. Normally, these immune responses appear in tandem. But in a subset of those who tested positive for COVID-19, Aleman found T cells but no antibodies.


殺し屋T細胞と抗体が対になって発生しないわけですね。



キラーT細胞については、

キラーT細胞の活躍 

これがわかりやすかった。

Much of this work is still preliminary, and scientists don’t know what it means in terms of assessing how well a vaccine will work or how well people are protected from severe forms of the disease. But one thing is becoming clear: antibodies might not be telling the whole story when it comes to COVID-19 immunity. “We shouldn’t just look blindly at antibody tests,” Aleman says.


集団免疫がどれくらい効果的か、あるいは、重病の場合どれだけ保護されるかについは、まだ、わからないが、コロナに対する免疫については、抗体検査があてにならないことは明確になってきた、と。
