Comment on Are MRNA vaccines any riskier than other vaccines?

• Legge@lemmy.world ⁨5⁩ ⁨months⁩ ago

  Herd immunity means it’s effectively eradicated, meaning that enough people are protected from it that the virus cannot readily find new hosts and basically “dies out” in the areas in which herd immunity is reached. That’s why severely immunocompromised people, eho often cannot get vaccines or cannot mount a response even if they do get vaccines, do not get, e.g., polio. If only the majority didn’t get the virus, those who are susceptible (the minority) still would, but this doesn’t really happen (in places where herd immunity is reached). Other places around the world may still have the virus floating around, but after a while at the herd immunity level in a location/ country, it is effectively eradicated.

  On top of what Legge said, herd immunity is for people who cannot get vaccines because of things like autoimmune diseases. who need to rely on the vast majority of people to be vaccinated to prevent the spread to them. It’s not for people who ‘just don’t like vaccines’ but have no medical reasons to avoid them

    I am well aware of that. It doesn’t disprove anything I’ve said and Legge is wrong. So good job?

      If herd immunity has been established and maintained in a population for a sufficient time, the disease is inevitably eliminated – no more endemic transmissions occur. If elimination is achieved worldwide and the number of cases is permanently reduced to zero, then a disease can be declared eradicated. Eradication can thus be considered the final effect or end-result of public health initiatives to control the spread of infectious disease. In cases in which herd immunity is compromised, on the contrary, disease outbreaks among the unvaccinated population are likely to occur.
