Hamsters Develop Protective Immunity to COVID-19 and Are Protected by Convalescent Sera.

[2greys]

In an animal model for COVID-19 that shares important features of human disease, scientists at the University of Wisconsin–Madison, the University of Tokyo and the Icahn School of Medicine at Mount Sinai show that prior infection with the SARS-CoV-2 virus provides protection against reinfection, and treatment with convalescent serum limits virus replication in their lungs.

Syrian hamsters, commonly found as pets, have served critical roles in understanding human infectious diseases for decades. The new study, led by Yoshihiro Kawaoka and published today (June 22, 2020) in the Proceedings of the National Academy of Sciences, demonstrates they are also a useful small animal model for researchers trying to understand SARS-CoV-2 and in evaluating vaccines, treatments and drugs against the disease it causes.

Fingers crossed this would mean if you have already had it your less likely to get it again

I can say with all probability that the source of our infection was the nursing home where Sharon works and two months later neither of us were re-infected, there have been no more positive cases there, thankfully, after that two months.
