I may have missed the answer, but I did not see it – if someone is scared of mRNA, why don’t you take J&J or old-fashioned Sinovac or Sputnik that are not worse than placebos! Are you afraid that Sputnik will launch you to space?! If this would help end the thread, I am ready to take sputnik myself.
on other notes:
>> Native Americans were exposed to European diseases hundreds died instantly. And then the infection rates went down until herd immunity was acheived.
It seems that majority of population died before the herd immunity was achieved … Those guys were at further disadvantage – they did not have domesticated animals and, thus, no zootic viruses at all. So, their immune system was totally unprepared. Those of us who had kids in schools or went there ourselves, were, Baruch Hashem, exposed to enough viruses to begin with.
>> However, they will need to be repeatedly injected every half a year or so, like flu shots are
I don’t have numbers but qualitatively, the first shots are way more important than the latter ones. Most immediate research measures antibodies in blood, but long-term protection is due to B-cells that will start fighting virus after being infected. so, getting those B-cells informed about a class of viruses is more significant step. This probably explains why vaccine against a new virus achieves 95% hard reduction, while flu vaccine only 70%. for a person who never had a flu, the reduction would be higher too. There is very limited medical data on B-cells so far, like tests with tens of people, so we will need to wait to see real life effects.
