IF AN UNVACCINATED PATIENT HAS JUST RECOVERED FROM A DIAGNOSED CASE OF INFLUENZA COMES INTO OUR CLINIC, SHOULD WE VACCINATE HIM?

Yes. Influenza vaccine commonly contains three influenza vaccine virus strains; two for A viruses and one for a B virus which are prepared based on circulating viruses from the previous influenza season. Infection from one virus type does not confer immunity to other types and it would not be unusual to have exposure to more than one type during a typical influenza season. By all means, vaccinate this person!
