Immunity against coronavirus infection wanes quickly and reinfections are common. Protection against severe illness and death was the original goal of vaccines. Vaccines against respiratory viruses rarely protect against full infection. Any notion of herd immunity is out of reach. Too many people are not vaccinated. The coronavirus continues to find ways to evade immunity.
This virus is always going to be with us. COVID detonates an immune response that can be deadly or debilitating.
The hope is that people will start to take all respiratory viruses more seriously, leading to lasting changes in mask wearing and ventilation.This does not seem to be the case.
