achieving herd immunity from COVID-19 through vaccination is still viable.
————————— ————————— —————————
I was under the impression that here immunity was about folks getting it all at once, basically. Getting over it. So everyone has the antibodies.
Isn’t that Why they used to ChickenPox parties back in the day? So, all the kids got it at once.
I thought the drugs/shots, “vaccines” were the exact opposite.
Vaccines can work to achieve herd immunity as well, but only the old school vaccines that were close to 100% effective, because they used actual material from the virus to mimic a natural infection.
The more modern vaccines don’t usually get anywhere close to that efficacy, so they are useless when it comes to achieving herd immunity.
Then there are other complications, like how quickly viruses mutate (very quickly, in the case of coronaviruses), and whether there are animal reservoirs that the virus can survive in (which is also true for COVID).
Chickenpox parties were so that everyone would get it while young, the older you are the sicker it makes you and more likely to cause permanent nerve damage.
Herd immunity is when enough people have either natural or vaccine derived immunity that it interrupts the spread of infection because the pathogen is unable to find new hosts to infect.
With a vaccine that doesn’t prevent infection, but merely reduces severity, herd immunity is simply not possible via vaccination.
