Does that mean that a natural immunity may offer protection against other coronaviruses that have a different spike protein structure? The logic being that the less targeted defenses built through a natural immunity would latch onto some other commonality?
- manwe150 6y agoNot necessarily. They will likely try to key on something very specific, as this reduces the risk of it triggering on you (creating an autoimmune disorder). So natural infection may be less effective. We assume that mutations to the virus that hide it from the natural defenses against a random part, but have no impact on the virility, are generally more frequent and numerous than mutations to the important spike protein.
- selcuka 6y agoAs far as I understand it is less likely for the spike protein to have a radical mutation and keep the ability to attach to cells at the same time. That's why the variants we are seeing have the same spike protein as other mutations of the virus tend to quickly disappear. If a new variant with a different spike emerges, I guess we'll call it SARS-CoV-3 and produce a new mRNA vaccine for it.
