Most of us unvaccinated have known this for a long time - the vaccines (if that is what they do) only produce antibodies for the very tip of the spike protein. Whereas natural immunity from a recovered infection produces antibodies to all sorts of proteins of the virus. So even in the case of mutations, natural immunity is far superior. Not sure why any Freeper would advocate for the vaccine for a healthy population group.
Speaking solely for myself as someone who's vaccinated (recommended by my specialist, due to a genetic immunocompromised condition) I've never advocated anyone who's otherwise healthy to get the 'vaccine.' Everyone I know who's healthy I did my level best to talk out of it including my long-term GF and both of my sons.
I got the 'vaccine' to protect myself. I've since learned that I had the CHINA VIRUS before getting the J&J shot, and that two of my medications (Humira & Fenofibrate) protect me from the damn' virus anyway.
So with my 'super immunity' as my specialist calls it, I've zero need for any booster shot. I have natural immunity and two meds that protect me.
Now if I'd had known I had the CHINA VIRUS before getting the J&J shot, I'd have never gotten it. We learned about natural immunity in high school, anyone who remembers knows it's better than any vaccine.
Luckily, my natural immunity is still with me and as a participant in a study tracking it for people with my genetic condition I go for antibody tests every two months. As luck would have it, I have to leave now for a blood draw for just that purpose.
Those of you considering getting a 'booster' ... DO NOT DO IT if you're otherwise healthy. Big Pharma is trying to make us all vaccine dependent to keep their money flowing. Don't fall for it. I won't. And I'm immuno-compromised.
