Herd immunity against measles requires that 90-95% of the entire population are immune, whereas vaccination coverage is measured as the percentage vaccinated of the target population â which only includes people who are eligible for vaccination.
- it must be possible to vaccinate the vast majority of the vulnerable population to produce herd immunity. What is herd immunity? This arises when a sufficiently large proportion of the population has been vaccinated. This makes it very difficult for a pathogen to spread within the population, ultimately stopping it. The percentage of the population needed to be vaccinated in order to achieve herd immunity is roughly 80%. Why can't everybody in a population be vaccinated? Babies and very young children cannot be vaccinated because there immune systems are not yet fully functional.
