So now, we have seen how the virus works, so Why gamble on vaccine? answer: Avoid deadly symptoms, Herd Immunity
Therefore, why not take vaccine? answer: stupidity, selfishness
There is no reason for people who have had SARS-cov-2 infection to get vaccinate then because it pretty clearly both by bench science and by historical observations to provide better and longer lasting immunity.
For my part I would immediately opt to deliberately get the nearly trivial SARS-cov-2 infection and a period of isolation rather than the gene therapy. Chances are that I am in the majority of people on earth who already had the infection and either suspected, it or never knew it since it's mild. If there were any honest antibody tests, I could know easily, but they have this PCR scam with ridiculous cycle thresholds which find anyone 'positive' when they want it to, and it never could find 'covid' even if it was done honestly.
'They' (or (((they)))?) obviously want almost everyone (with the exception of themselves and their rich friends (or tribe?)) to get the experimental injection for some reason, and the bullshit about 'herd immunity' and whatever are just that; a highly obvious and transparent load of bullshit with some 'scienc-ee sounding' terms thrown around to rope in the ignorant mouth-breathers who don't know how to read and research things.
