Every day when I see patients in my surgical clinic, some are offered a procedure to help them feel better. Whether it is a minor surgery like a tonsillectomy, or something larger scale such as tumor resection, I have a full discussion with the patient regarding the benefits and risks of doing "something." Each time I go over the common minor risks of an intervention and the exceedingly rare, but potentially very serious risks that can occur. I also review with them the risks of doing "nothing" - of what may happen if they don't have surgery. Vaccination is no different.
