Herd immunity (or community immunity) describes a form of immunity that occurs when the vaccination of a significant portion of a population (or herd) provides a measure of protection for individuals who have not developed immunity. Herd immunity theory proposes that, in contagious diseases that are transmitted from individual to individual, chains of infection are likely to be disrupted when large numbers of a population are immune or less susceptible to the disease. The greater the proportion of individuals who are resistant, the smaller the probability that a susceptible individual will come into contact with an infectious individual.

Vaccination acts as a sort of firebreak or firewall in the spread of the disease, slowing or preventing further transmission of the disease to others. Unvaccinated individuals are indirectly protected by vaccinated individuals, as the latter will not contract and transmit the disease between infected and susceptible individuals. Hence, a public health policy of herd immunity may be used to reduce spread of an illness and provide a level of protection to a vulnerable, unvaccinated subgroup.

This is why everyone must be vaccinated, and by not doing so, you are actually putting the community in danger.

Sweetie of the Day - December 23rd, 2013

Today’s sweetie is the amazing Sir Patrick Stewart, well-known for Captain Jean-Luc Picard on Star Trek: The Next Generation, Professor Xavier in X-Men, and various stage roles with the Royal Shakespeare Company. In recent years, he has also delved into charity and activist work.

Stewart has worked with various charitable organisations like Amnesty Intertional, Refuge, and Combat Stress, as well as giving his name to a scholarship at the University of Huddersfield. He is well-known for using his role in the public eye in order to bring attention to discussions around domestic violence, feminism, and PTSD.

For using his platform as, as he puts it, an “old white man” to advocate for awareness and better resources for human beings everywhere, Sir Patrick Stewart is our sweetie of the day.
