Question

Quizplus · Accepted Answer

When widespread vaccination is administered to a population, it can create herd immunity. This means that a large enough portion of the population becomes immune to the disease, which reduces the likelihood of an outbreak and provides protection for those who cannot be vaccinated, such as individuals with weakened immune systems. Herd immunity can only be achieved when a significant proportion of the population receives the vaccine.
