About that immunity thing

COVID-19

If there is such a thing as immunity to COVID-19 through antibodies (such as a vaccine might stimulate production of), it might be very—this is not a good thing—specific:

The patient, a 25-year-old Nevada man, was infected with two distinct variants of SARS-CoV-2, the virus that causes Covid-19, within a 48-day time frame.[1] . . . “We need more research to understand how long immunity may last for people exposed to SARS-CoV-2 and why some of these second infections, while rare, are presenting as more severe.”[2]

I’m hoping this T-cell thing[3] that I think protects me from so many varieties of creeping crud is for real.
