Over a dozen scientists say the threshold to reach coronavirus herd immunity might be lower than they initially projected, The New York Times reported Monday.
According to scientists, herd immunity will be reached when the virus is unable to spread broadly because there are not enough vulnerable hosts, the Times reported. The consensus among scientists has been that 70% of a population needed to be immune through either vaccination or survival to reach herd immunity, according to the Times, but now several researchers claim that threshold could be 50% or lower.
