> Vaccination is likely an option for long term COVID-19 herd immunity. To achieve herd immunity for measles at least 90-95% of the population need to be vaccinated. A disease like polio is less contagious, and 80-85% of the population would need to be vaccinated for herd immunity to work.
https://www.ovg.ox.ac.uk/news/herd-immunity-how-does-it-work It suggests our immunity to SARS-CoV-2 does not last very long at all — as little as two months for some people. If this is the case, it means a potential vaccine might require regular boosters, and herd immunity might not be viable at all.
