I understand and hope that vaccination/natural immunity will prevent virus from spreading. But currently we only have evidence of decreased risk of sickness. Virus may still live in respiratory system and spread asymptomatically. BTW, vaccination strengthens lymph/blood system immunity, but not nose/throat lining, where viral aerosol producing.
