Gato - What do you think of an Oxford study released today about previous infection?

In UK news, the study is described as: "Previous Covid infection may not offer long-term protection".

The study itself is titled "Divergent trajectories of antiviral memory afterSARS-Cov-2 infection". From a small group of health care workers (n=78), using machine-learning models, the researchers concluded: "Importantly, previous infection may not give ongoing protection against [variants of concern] months later, and people with asymptomatic infection had lower responses at all time points across many of the immune parameters we measured."

I respect your analysis of medical research, so I'd be very interested in how you find this Oxford study, particularly in comparison to the Ohio study.

Un saludo,
