5/8/21 As long as some people remain hesitant to get the shot, the virus will continue to circulate – and could cause infection in others, whose immune systems aren’t vigorous enough to fully defend them.
They’re insulated only when so many other people are fully vaccinated that the virus can’t find enough people to infect, then stops its spread.
The vulnerable include elders, people born with faulty immune systems and people who must take immunosuppressant drugs for illnesses ranging from cancer to rheumatoid arthritis. Also at risk are people who would love to be vaccinated, but can’t because of life-threatening allergies.
