A poll published by Gallup in early August found that 35% of surveyed Americans would decline a Covid-19 shot offered to them at no cost. I have seen other studies that say 50% of Americans will not get the vaccine. And on social media sites I have seen discussion and comments about why folks are so reticent to get the vaccine. Let me address the concerns. Continue reading
