covid19的。
唉，现在写软文骗钱越来越容易了。
Like the CDC study, these researchers looked for antibodies in the blood
that are taken as evidence of coronavirus infection, and can be detected as
early as two weeks after a person is first infected.
It can be difficult to distinguish antibodies that neutralize SARS-CoV-2,
the virus that causes COVID-19, from antibodies that fight other
coronaviruses, including some that cause the common cold. Researchers in
both the NIH and CDC studies used multiple types of tests to minimize false
positive results, but some experts say it still is possible their 2019
positives were infections by other coronaviruses and not the pandemic strain.

，因为这玩意本来就和已有的天然病毒类似，改造的只是一小段基因，不一定会反映在
抗体上。
