群体免疫真的靠谱吗？西班牙新研究提出质疑

该报告的作者称：“尽管新冠病毒对西班牙造成了很大冲击，但是抗体的普及率依然偏低，显然不足以产生群体免疫。要达成群体免疫，就不得不接受易感人群大量死亡和让医疗系统超负荷的附带损害。在这种情况下，未来的疫情防控中必须实行社交隔离措施，努力发现和隔离新病例及其密切接触者。”

Herd immunity is achieved when immunity is built among the general population through some exposure to a virus or infection. The strategy has been cited by health officials in Sweden, which controversially did not impose a lockdown.

群体免疫的理念是，某种程度的接触或感染病毒，从而让整个群体产生抗体。瑞典卫生官员曾引用了这一策略，该国没有实施封锁的决定备受争议。

However, many experts are skeptical about the effectiveness of such an approach, warning that immunity to the coronavirus is not guaranteed after infection or may only last a short while.

然而，许多专家都对这种方式的有效性感到怀疑，并警告称，感染新冠病毒后不一定会产生免疫力，或者免疫力可能只能延续一小段时间。

Speaking on CNBC’s “Squawk Box Europe” on Monday, Danny Altmann, professor of immunology at Imperial College London, said it was not a “safe bet” to rely on immunity to Covid-19 as a strategy for coping with the pandemic, adding that herd immunity strategies were “probably never going to work.”
