I understand your reasoning, however can you then explain why those who survived SARS-CoV-1 over 17 years ago still have immunity today?
While SARS and the common cold are both in the corona virus category due to their structure, they are still different as shown by the long lasting immunity for SARS survivors versus short term immunity we see with the common cold.
The reason for the short-term immunity is because there are more than 160 strains of rhinovirus, and developing a vaccine or antibodies that target so many strains at once (all of which can mutate, of course) is nigh impossible with our current technology.
Exactly.
Yes. You are totally immune to the strain that you get sick from. Totally. It's a mutated strain that can get you sick 3 months later. The human immune system is amazing and viruses are equally amazing. It's a constant battle. So - yeah, people who got "Covid-19" won't get "Covid-19" again - they'll get a mutated strain.
Not all viruses are "food-chain survivors" ... just like the animal kingdom ... and viruses have a much shorter life span than typical animal species'. Some never achieve what they started out to do. Take a good look at HIV (a deep look is necessary, my mother-in-law has it) and see that they claim medications are curbing it's mortality rate? Is it really the medications or did the virus adapt to a symbiotic relationship with humans? ... It's phenomenal what has happened to HIV over the years.
