I used to develop vaccines for veterinary use. Developing a vaccine is like creating a recipe. Once you have the recipe developed it is relatively easy to "plug in" a different virus to make a vaccine using established procedures. This shortens the time needed to develop vaccines for different viruses by using the established techniques. This same method was used for the COVID vaccines making it possible to turn out reliable vaccine in a relatively short period of time. As with any vaccine or any medical procedure, some people may experience side effects. The disease is mild in some people, but other people end up with a wide range of long-term effects. A young, healthy Clemson football player had mild COVID symptoms, yet ended up with long-hauler's symptoms forcing him to quit football. You can choose to take your chances with the disease or the vaccine. That football player suffered a long time before getting the COVID vaccine...which eliminated his long haul symptoms and he was eventually able to return to football the following year. COVID will be around a long time. It is my belief we can help reduce the impact of wide-spread disease stressing our medical community by each of us doing our part to reduce the spread and severity by vaccination and masking. It is a pretty small thing we do to help our fellow citizens and our ever-tiring medical providers.
