Its not hte virus mutating that causes it, that obviously is a factor that can make it worse. But the issue is actually the human immune response, it becomes attenuated itself in this case, same with tetnus, its the same virus you just loose immunity over time.
For the record all viruses of the cornovirus sub-type (which includes several that cause the common cold) have this effect. Its part of the reason why a cold vaccine has never been an option.
@realcaseyrollins @freemo I will take it if I have to, but I do not like the side effects as it makes me super tired & gives me a hunger for meat (well, the latter is not too bad I guess 😂).
@freemo @darnell Not exactly pro vaxx here but I’d have to agree on this take here, since the virus keeps mutating.
