Which cities in Zimbabwe have reached herd immunity?
Herd immunity occurs when enough people in a population is immune to an infectious disease, either through vaccination or past infection, reducing its spread. The percentage needed for herd immunity varies by disease. For Covid-19, the exact vaccination rate required to achieve herd immunity is unknown, but some experts estimate it to be between 60%-70%.
The World Health Organization (WHO) considers this an important research area. However, Zimbabwe, like some other countries, has stopped reporting or changed how often it reports COVID-19 vaccination rates to the WHO. There is currently no data available on Zimbabwe's Covid-19 vaccination rate.
