If a person has existing health conditions that might create reactions to these vaccines....or they rarely get together with any family or friends, or they seldom venture into any venues of crowds of people, they might very well consider these vaccines unnecessary. However, if they are fairly active and healthy, and enjoy getting out of the house, getting vaccinated becomes increasingly important...given all the unknowns of this virus.
If this virus isn't brought under control in coming months, and it doesn't continue to mutate into even worse variants, I can easily see the day coming where it will be Mandatory to present some sort of ID that shows that an individual has been vaccinated before they are allowed to go anywhere.
While the numbers appear to be improving in some areas, others are getting worse. Unless strict travel, etc., regulations are implemented, and enforced, this virus will continue to spread, and ultimately result in forcing everyone who doesn't want to stay home 24/7, to get vaccinated.
