Public health experts say a vaccine may be the best chance of stopping the coronavirus. Yet even though it could be months or more than a year before a working vaccine is ready, groups that have spread misinformation about immunizations in the past are raising doubts, and that has health officials concerned. Some claim vaccine trials will be dangerously rushed; others say better treatments are being ignored to enrich vaccine makers. Then there are more far-reaching claims that Microsoft founder Bill Gates plans to use a vaccine to inject microchips into people to reduce the world’s population. Experts say such claims could prove lethal if they undermine support for vaccines. Fond du Lac County Public Health Officer Kim Mueller says it’s very frustrating, because a vaccine is designed to prevent a disease. “When you think about treatment, a treatment is for somebody that has that disease. We’re trying to prevent that disease from happening in people,” Mueller told WFDL news. Mueller says until there is a vaccine it’s going to be difficult to stop the spread of COVID-19.
