[ANALYSIS] COVID-19 herd immunity | It’s not going to happen, so what next?
Instead we should be talking about how to live with the virus. The tremendous success that’s materialised with COVID-19 vaccines allows us to do this, without actually getting into the herd immunity threshold.
Secondly, failing to face up to the reality that herd immunity can’t be achieved will mean that countries like South Africa will continue to believe that ongoing restrictions will get them there. That will compromise the lives of people on multiple fronts – including education and livelihoods.is when someone infected by the virus won’t, on average, infect another person.
So herd immunity essentially means that you have brought about an absolute interruption in the chain of transmission of the virus in the population in the absence of other interventions that too could interrupt virus transmission such as wearing of face masks. The second change is that the virus has shown an ability to have mutations that make it resistant to antibody neutralising activity induced by past infection from the original virus, as well as antibody responses induced by most of the current COVID-19 vaccines.
