wrong. People have had COVID twice, with no vaccine involved. Be really careful with your homework, and more so with what you print.
Not getting vaccinated does nothing but screw up our medical system with many severely ill patients. The country is bankrupt in more ways than one, why add this COVID mess to it?
BTW there's no such thing as immunity to COVID, the flu, the common cold or malaria and so on. When disease gets eradicated the pathogen winds up not in circulation, which is the goal of vaccine programs, not the development of immunity. Subtle stuff, and real.
Get vaccinated, wear a mask when appropriate, practice safe behavior and help take COVID (the super cold) out of circulation.
