Why ignore natural immunities?
Let me ask you a question: would you have sex with someone who has gonorrhea, relying upon your natural immunity to protect you? It's not even a deadly disease.
Why the attacks on anything other than the vaccine and endless boosters?
Because the "anything other" stuff are ineffective excuses to avoid the vaccines, which ARE effective. If you want to take a placebo for yourself, fine. If you are going to try to influence others to do the same, then fuck you and expect to get attacked.
Seriously, you would pay hundreds of dollars for an animal medicine that literally makes you shit out the lining of your intestines, and believe that action somehow provides you immunity against COVID, rather than taking a FREE vaccine? Yep, you would. Because DURR I OWND THE LIBS DURR.
