激活了免疫系统杀死癌细胞， 这是有可能的。

反疫苗的继续秀

A 61‐year‐old man with stage III Hodgkin lymphoma was hospitalized for the infection of Covid-19 in the UK. He was hospitalized for 11 days and did not receive any cancer treatment. Four months later, the PET-CT scan result showed that his lymphoma was largely gone!

For a 61-year-old U.K. man, having COVID-19 may have helped save his life.

The unidentified Cornwall man, whose case is documented in the British Journal of Haematology, was diagnosed with Hodgkin lymphoma during a checkup last summer, according to Wales Online. His week went from bad to worse a few days later when he was rushed to hospital with a severe case of COVID-19. After a gruelling 11 days of intensive care, during which he was put on oxygen to help heal his damaged lungs, the patient was discharged, fully recovered from the virus.

Correlation is lot enough, need to show causality

你看文章了吗，这个说的是得了covid癌症没了。想justify疫苗也不带这样的。谁也不会为了治癌症特意去得covid吧。同样，我们也不能因为有可能杀死癌细胞而去打疫苗 。

其实这正是mrna被担心的autoimmune问题的另一个方向的展现 。杀死癌细胞是好的副作用，杀死正常细胞不就是人体的损失了吗？谁能说的准免疫系统就能恰到好处的杀掉不好的细胞，而保留好的细胞，或仅有无关痛痒的影响？

这个很有意思，说不定歪打正着，疫苗成了癌症克星了呢

某些发展慢的淋巴癌的确确诊后不会马上开始治疗，这是网上看到的

If you have a type of non-Hodgkin's lymphoma (NHL) that grows slowly, don't be surprised if your doctor suggests you hold off treatment. It's an approach called "watch and wait," and it might be a choice for you if you don't have any pain or other symptoms.

先不说那玩意能不能歪打正着地治疗癌症（不排除这种可能性，毕竟那玩意不可知的名堂很多），光说这人，得了淋巴瘤，1年半不治疗，居然还活得好好的， 这淋巴瘤也太弱了吧？误诊了？慢淋白血病？
