What herd immunity is — and why it isn’t a wise strategy for handling COVID-19

“Herd immunity itself is a concept by which epidemics tend to fade when a certain percentage of the population have already had it …. according to Andrew Noymer with University of California, Irvine. He’s a population health and disease prevention expert. … “This vaccine that we’re all hoping for is a way to get immunity, but it’s a way to get immunity without infection, without getting sick. The vaccine is a shortcut to immunity. Pursuing a vaccine is also chasing after herd immunity, but it’s doing it in the good way,” said Noymer. Most public health experts like Noymer agree herd immunity is not really a wise approach to defeat COVID-19.
