After seeing the headline I was happy about the findings. When digging in deeper I found this:
“Study limitations include lack of direct neutralization assays, the fact that antibody levels alone do not directly equate to immunity,
4,
6 the cross-sectional study design, a convenience sample with an unknown degree of selection bias due to public recruitment, self-reported COVID-19 test results, the study population being largely White and healthy, and lack of information on breakthrough infections. Participants were given only 1 month to complete antibody testing, which may have contributed to the 52% rate among those invited to test.”
“Although evidence of natural immunity in unvaccinated healthy US adults up to 20 months after confirmed COVID-19 infection is encouraging, it is unclear how these antibody levels correlate with protection against future SARS-CoV-2 infections, particularly with emerging variants. The public health implications and long-term understanding of these findings merit further consideration.”
That’s a lot of limitations. Let’s hope further, more in-depth studies show its correct.
On a personal note, in looking at the comments I thought I was watching a certain cable news channel. Then I dug into the doctor more and he’s a regular contributor on the channel. Doesn’t make me believe or not believe what he says but it does seem to be a agenda. Hopefully I’m reading it wrong.
