I have adult patients going back to school who must show proof of MMR vaccine and are unable to retrieve their immunization records. What are my options?
Your options are to either bring the person into compliance with the school entry requirement by vaccinating or to perform serologic testing for all the antigens for which documented immunity is required. There is no evidence that adverse reactions are increased when MMR is given to a person who is already immune to one or more of the components of the vaccine.
