First, natural immunity after recovery from Covid is much broader and better protection than the vaccine.  Second, we have no idea what side effects could occur 10 or 20 years from now.  Third, some people have medical conditions that would be worsened by taking the vaccine and they have been warned not to by their physicians.  Allow people the freedom and trust them enough to do what is best for them.  If you believe that the vaccine protects people, then those who are vaccinated have nothing to fear from those who are not.  The vaccine is not right for everyone, so let people choose for themselves.  That way we will all be better off and our guaranteed freedoms will be intact.
