My patient caught Covid-19 twice. So long to herd immunity hopes.
Emerging cases of Covid-19 reinfection suggest herd immunity is wishful thinking.
Decreasing antibody titers don't mean that people don't have resistance. T-cell reactivity is definitely a thing and appears to be an explanation for why a good portion of the population has resistance to begin with, which is something that all the early models from the epidemiologists missed entirely.Immunity to Covid-19 could disappear in months
There's way too little background on the patient described in Jack's article. Let's start with the most basic question: Does he have a healthy immune system?
But if the speculation in these articles is correct, then we'd better focus on developing effective treatments rather than vaccines because vaccines won't confer long-lasting immunity either.
