A quick glimpse of the headlines brought forth a gloomy article titled: “Studies confirm waning immunity from Pfizer's COVID-19 vaccine". The story conveyed a study of Israeli health care workers, which revealed decreasing levels of circulating antibodies that protect against severe infections. It was accompanied by a summary of a similar and no less ominous portent arising from a Qatari study.

As an immunologist and someone who wears both the hat of a scientist and historian, has taken a long view of the pandemic, please be assured that neither of these stories is neither particularly surprising nor news worthy. These outcomes are certainly not such to cause public concern and indeed can be described as something we have all been craving for these past twenty-plus months: normal.

一言以蔽之，我们的免疫系统令人惊讶。我们的身体都通过包括多种不同抗体和细胞的防御能力来保护我们的生活的每一刻。一旦实现了持久的免疫力，尤其是通过疫苗接种，这些防御者就准备就绪，可以以显着的速度和进取心动员。

这是非常正常的，并且普遍认为血液中的抗体水平会随着时间的流逝而减弱。对于所有不同的病毒，细菌和其他潜在的有害药物而言，我们的免疫系统在我们的生命中暴露于我们的一生中都是如此。我们的身体根本无法满足每天，每天和余生中高水平供应的每种抗体所需的能量。

Rest assured that all of us who have been vaccinated retain the ability to call up these antibodies and cells as needed. This fact gets at another point that has been repeatedly mis-communicated.

The three remarkable vaccines created and approved by the FDA over the past months were not designed to prevent infection from the SARS-CoV-2 virus. Rather, they were created to prevent severe disease and death from the virus. Some viruses are too nimble and cannot be stopped from infecting us. However, we can prevent these infections from getting out of control by mobilizing an immune system that has already been alerted to the possible presence of a deadly pathogen. This is how the COVID-19 vaccines work.

确实，这些疫苗和其他疫苗可以被认为是“超人人类”，因为它可以传达一种无法通过自然感染来实现的保护幅度。这就是为什么即使过去被感染的人仍然需要接种疫苗的原因。

总而言之，对于那些被接种疫苗的人：感谢您滚动袖子并帮助保护我们的世界免受致命大流行的影响。更重要的是，请不要对疫苗失去信心，也不要因声称您的重要贡献徒劳的头条而过于焦虑。他们肯定不是。
