What is it?
Herd immunity (also called herd effect, community immunity, population immunity, or mass immunity) is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity. Immune individuals are unlikely to contribute to disease transmission, disrupting chains of infection, which stops or slows the spread of disease. The greater the proportion of immune individuals in a community, the smaller the probability that non-immune individuals will come into contact with an infectious individual. (Wikipedia as of 2021-08-12)
Natural Immunity is the best (and it can be argued “the only”) way to achieve herd immunity because natural immunity uses all the other layers of the immune system to create antibodies specific to variants. Vaccines induce antibodies to a specific strain of a virus but not variants unless booster vaccines are provided. However, a virus can mutate with infinite permutations so getting artificial vaccine boosters to combat infinite variants makes vaccines useless.
Discussion
- Professor Andrew Pollard – Oxford Vaccine Group – came up with Astra Zeneca vaccine
Herd immunity cannot be achieved by vaccines because of variants.
- WHO changed definition of Herd Immunity so that it can only be achieved by vaccination.
- Herd immunity is a well defined epidemiologic term. WHO is re-defining it to meet a specific agenda and objective. More propaganda.
- On the other hand:
- Natural immunity is adaptive.
- It can learn to fight variants. Vaccines cannot.
