Which cities in Zimbabwe have reached herd immunity?
Herd immunity is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection. The share of people who need to be immune in order to achieve herd immunity varies with each disease. The proportion of the population that must be vaccinated against Covid-19 to begin inducing herd immunity is not known. The World Health Organization has said that this is an important area of research. Some experts believe herd immunity against Covid-19 can be achieved if between 60%-70% of the population is vaccinated.
While there is no data on the rate of herd immunity per city in Zimbabwe, according to Zimbabwe’s Ministry of Health as of 16 May 2021, a total of 581,615 people had been vaccinated against Covid-19 which amounts to 4% of the population.
