If you are a person with underlying conditions, over the age of 50yrs of age, then by all means take the two vaccination shots. If you've have had the Covid-19 you're already immune. All others have the choice to vaccinate or not, just as women have the choice claiming their bodies their choice.
As of September 20, 2021, 43,644,820 people have been diagnosed as survived Wuhan Covid-19 virus and
more than 181 million people in the United States had been fully vaccinated against COVID-19.
Therefore more 224,644,820 are theoretically immune from Covid-19.
The total number of people living in America as of the 2020 census is 331,449,281
That equates to 68 percent of the country is immune to the Covid-19. Now consider all the illegal aliens living in America that have not been immunized (Estimated between 30 to 40 million) that leaves 70 million Americans mostly children that have not been vaccinated.
According to:
POP1 Child population: Number of children (in millions) ages 0–17 in the United States by age, 1950–2020 and projected 2021–2050
