Oh shyt! So if this is the case, it isn’t actually an antibody dependent enhancement response to the older coronaviruses like in a dengue infections or the MERS study with rabbits but actually the same as the H2N2/H3N2 outbreaks in 50s and 60s where exposure to similar influenza strains offered protection!
I would see that as good news .. I wonder how sophisticated antibody tests for other common coronaviruses are?
