Darwin did dress up this year, but I guess I didn't get a picture of him. He wore black pants and a black t-shirt that said "Budget Ninja Costume" on it. =)
"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 are less likely to 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. Since only a small fraction of the population (or herd) can be left unvaccinated for this method to be effective, it is considered best left for those who cannot safely receive vaccines because of a medical condition such as an immune disorder, organ transplant recipients, or people with egg allergies. "Because this isn't a fail safe method of avoiding these diseases, Caleb is now on a schedule to receive most of his original shots over again! As of today, he's had nine of his childhood immunizations re-administered. Some of the vaccines (live virus types) cannot be given to him at all until he is at least 24 months past his transplant date... in fact, we have had to defer three live vaccines for Kalia until that time as well.
