An ongoing lawsuit in the UK over Covid vaccination has caused a global furore, including in India.UK’s The Telegraph has reported that AstraZeneca admitted in court documents that its Covid vaccinecan cause blood clots in rare instances. The pharma major is facing a class action lawsuit over claimsthat its vaccine, developed with University of Oxford, caused death and injuries.

英国正在进行的关于新型冠状病毒疫苗接种的诉讼引起了全球的骚动，包括在印度。英国《每日电讯报》报道，阿斯利康在法庭文件中承认，其新型冠状病毒疫苗在极少数情况下会导致血凝块。制药专业面临集体诉讼，指控其与牛津大学合作开发的疫苗造成人员伤亡。

In India, where themajority of people were administered Covishield, as the AstraZeneca vaccine was known here, thenews has caused concern. Dr Shahid Jameel, virologist and research fellow at Green Templeton College,University of Oxford, tells Indulekha Aravind that there is no cause for worry as benefits far outweigh risks.

在印度，由于阿斯利康疫苗在这里被称为Covishield，因此大多数人都接受了Covishield治疗，这些新闻引起了人们的关注。牛津大学格林坦普顿学院的病毒学家和研究员沙希德·贾米尔博士告诉Indulekha Aravind，没有理由担心，因为好处远远大于风险。

But playing politics with this, he says, is both wrong and dangerous. Edited excerpts: AstraZeneca’s admission in a UK court that its Covid vaccine can cause a rare side-effect has sparked concern, especially in India. Is there cause for worry?This is not new. It has been coming up since 2021. Based on The Telegraph report that everyone seems to be referring to, what did AstraZeneca admit? It said there was a very rare chance of something called TTS.

但是，他说，用这个玩弄政治是错误的，也是危险的。节选：阿斯利康在英国法庭上承认其新型冠状病毒疫苗会产生罕见的副作用，这引发了人们的担忧，尤其是在印度。有理由担心吗？这并不新鲜。它从2021年开始出现。根据每个人似乎都在提到的电报报道，阿斯利康承认了什么？它说有一个非常罕见的机会被称为TTS。

TTS is thrombosis and thrombocytopenia syndrome. Thrombosis means blood clots, thrombocytopenia means a reduction in the level of platelets. Platelets prevent bleeding so people who have low platelets bleed at the slightest provocation and this bleeding leads to internal clotting. A dengue virus infection can also cause thrombocytopenia.

TTS是血栓形成和血小板减少综合征。血栓形成意味着血凝块，血小板减少意味着血小板水平降低。血小板可以防止出血，因此血小板含量低的人在最轻微的刺激下就会出血，这种出血会导致内部凝血。登革热病毒感染也可导致血小板减少症。

So they have admitted to a very rare event. Now, how rare is very rare? Different countries have computed their own risk. The UK computed a risk of four cases of TTS in 1 million vaccinated people. The EU has computed it to be one in 100,000 and Australia 2-3 per 100,000. So this is extremely rar.

因此，他们承认了一个非常罕见的事件。现在，有多罕见是非常罕见的？不同的国家计算了自己的风险。英国计算出100万接种疫苗的人群中有4例TTS的风险。欧盟计算为每10万人中就有一人，澳大利亚为每10万人中有2-3人。所以这是非常罕见的。
