有没有原文索引？
不知挪威的几个重症是不是脑栓塞？
血栓，血小板减少，跟澳洲病例一致。初步数据就是致病率差不多1%%，实际可能更高，因为谁也不知道没有症状的或者症状轻微的有多少。考虑到新冠的致死率也不过1‰，挪威暂停接种不过是很自然的反应。都到这样了，还有人信誓旦旦的洗地，大写的服。
The specialist also said that there was “no other medical history in these patients that could give such a strong immune response”. He stressed that antibodies in general are not the cause of the problem, which involves “very specific” antibodies.
The reaction in the cases in question involved blood clots and a lack of platelets, VG writes.
When asked if he thinks the findings mean that the vaccination should be stopped, Holme said that this was up to Norwegian Medicines Agency to decide.
“I have no idea about that, it is not me who should assess it,” he said according to Aftenposten.
Norway has already suspended the use of the AstraZeneca vaccine. So far Norway has vaccinated 120,000 people with the AstraZeneca vaccine.

还有具体的原因分析的。抗凝血剂肝素和PF4结合，但是某些人会产生抗体攻击结合物。
The VIPIT story began on 27 February, when Sabine Eichinger, a hematologist at the Medical University of Vienna, was confronted with an unusual patient. A 49-year-old nurse had sought help at a local hospital the day before, suffering from nausea and stomach discomfort, and was transferred to Eichinger’s hospital. She had a low platelet count and computed tomography scans found thromboses—blood clots—in the veins in her abdomen and later in arteries as well. “There was little we could do at this stage,” Eichinger says. The patient died the next day.
The combination of low platelet count, or thrombocytopenia, and clots kept Eichinger thinking, however. “It’s very striking,” she says. Platelets, also known as thrombocytes, help form blood clots, so low levels usually lead to bleeding, not clotting. “You would think that low platelets and thromboses are opposites really.” One condition where they occur together is called disseminated intravascular coagulation, when severe infection, injury, or cancer trigger clotting so widespread it uses up all the platelets, “but she had none of these things,” Eichinger says.
The unusual combination also appears in HIT, which can occur in patients given heparin as a drug. Heparin binds to a protein called platelet factor 4 (PF4), forming a complex. For reasons that aren’t understood, some people produce antibodies against the complex, setting off an out-of-control clotting reaction. Eichinger’s patient had not received heparin, but she had gotten a shot of the AstraZeneca vaccine 5 days before her symptoms began. “I thought maybe this is some kind of immune reaction,” Eichinger says.
