If a significant number of seniors refuse the vaccine they are not only putting themselves at risk, but also the health-care and hospital staff who will be required to treat them if they become ill from the many illnesses common to the elderly. Because those who receive the vaccine will receive a COVID-19 card, I believe there are other concerns for those who refuse the vaccine. They need to know if the card will be used for purposes other than tracking. Will it be required before one can travel, before one can be admitted to hospital or even before one can have contact with friends and family?
