Collective immunity, often referred to as herd immunity, is a cornerstone concept in epidemiology. It’s not just about individual protection but about constructing a communal shield against measles. At its core, herd immunity signifies a scenario where a significant portion of a population becomes immune to a disease, reducing its spread. This immunity can arise either from previous infection or, more desirably, from vaccination.

There’s a threshold to achieve herd immunity, which varies for different diseases. For measles, one of the most contagious viruses known, a whopping 95% of the population needs immunity to effectively halt its spread. That’s a testament to the virus’s infectious prowess.

Herd immunity isn’t just about those who are vaccinated. It’s about safeguarding those who can’t be – newborns, individuals with certain medical conditions, or those with weakened immune systems. When the majority are immune, these vulnerable groups benefit from the reduced circulation of the virus. (14)
