Herd Immunity
Herd immunity is a public health concept where a large portion of a community becomes immune to a disease, either through vaccination or previous infections. When enough people are immune, the spread of the disease slows down significantly, protecting those who cannot be vaccinated, such as infants or individuals with certain health conditions. This collective immunity reduces the likelihood of outbreaks, making it safer for everyone. Ultimately, achieving herd immunity can lead to the control or eradication of certain infectious diseases within a population.

Herd immunity occurs when a significant portion of a population becomes immune to a disease, either through vaccination or previous infections. This collective immunity helps protect those who cannot be vaccinated, such as individuals with certain medical conditions. When enough people are immune, the spread of the disease slows and can even stop, reducing the likelihood of outbreaks. Achieving herd immunity is crucial for controlling infectious diseases and ensuring the health of the community, as it lowers the overall amount of the virus or bacteria circulating and safeguards vulnerable populations.

Herd immunity is a public health concept that occurs when a significant portion of a population becomes immune to a disease, either through vaccination or previous infections. This reduces the overall spread of the disease, protecting those who are not immune, such as vulnerable individuals who cannot be vaccinated. When enough people are immune, the transmission of the disease decreases, making outbreaks less likely. Herd immunity is crucial for controlling infectious diseases and is typically achieved when 70% to 90% of the population is immune, depending on the specific disease.
