I don't want to get in a wide ranging discussion of this here, but if YOU get vaccinated, YOU will have immunity against the virus, without regard to what some idiot does. Anti-vaxxers are of great concern to public health officials but not to individuals. It's the same with masks. If YOU do not wear one, YOU may get the virus, but if 90% of all people wear masks, the remaining 10% will not cause a public health crisis. Now we may want to argue that anti-maskers are inflating health care costs by their actions, which is true, but we have that same issue with respect to smokers, drug addicts, alcoholics, etc.
