Either way, studies seem to suggest that the virus develops some resistance. It can allow it to continue to flow … even after we have reached possible collective immunity, by vaccination or by infection.
The big difference from the situation in the last two years will be that SARS-CoV-2 can no longer infect several people or replicate several times in each person it infects. Therefore the chance of new versions appearing will be considerably reduced.
Corona virus like the others?
Four corona viruses (HCoV-OC43, HCoV-229E, HCoV-NL63 and HCoV-HKU 1) are responsible for frequent and often mild respiratory infections, as well as for 10 to 15% of colds.
Re-infections with these four common corona viruses are likely due to the development of the viruses, new mutations that allow them to occasionally thwart our immune defenses.
If immunity to SARS-CoV-2 were to decrease as it does with these corona viruses, then SARS-CoV2 will continue to cause recurrent infections. In an optimistic scenario, covid can turn into a recurrent cold.
