Some refusers are not refusing indefinitely. They are waiting to see what happens to others. This is especially true for parents who are reluctant to vaccinate their teenage children who have now been approved to get the vaccine. We can call that wrong, and we can call it over-cautious; but we can’t really call it unreasonable. Some people are afraid the vaccines may have adverse effects in the long term. Because they are so new, we won’t know for a long time yet. Time will tell, but the current very real danger from the pandemic far outweighs speculation about the remote possibility of harm in the future. Some people who haven’t been vaccinated don’t actually reject the vaccines. Some say they will get the vaccine if it is required, for instance if it is a condition of employment. Some are procrastinating because of their fear of needles. A friend of my daughter’s is a case in point. He knew he should get vaccinated but kept delaying. He deeply regretted his procrastination when both he and his wife came down with COVID-19 and he ended up spending a week in the hospital.
