WHO: Polio Outbreak in Philippines Caused by Vaccine Posted by Admin on Friday, November, 22 2019 and filed under News Key topics: Polio
Source: WHO Note: The notion of "herd immunity" originally applied in the context of natural immunity which is acquired after contracting the disease in early childhood. If roughly two-thirds of the population have natural immunity, then herd immunity will be provided to the rest of the population. And as natural immunity decreases below this level, others will catch the disease until herd immunity is reached again. This notion of natural herd immunity was applied to vaccination, which is artificial and unnatural. However, vaccine caused outbreaks of disease have been shown to occur in 100% vaccinated populations.
