I have always used Neosporin with great results. Never a problem with it, EVER. Last February I got the Shingles vaccination. No reaction, no problem. However, I have noticed in recent months that, when I have a need for a healing ointment, and use Neosporin, the wound, scrape, cut or whatever does not heal and the skin around it becomes inflamed. I've seen posts that if you are allergic to Neosporin you should not get the shingles vaccine. Is the reverse ever seen? Does the shingles vaccine CAUSE one to develop a reaction to Neosporin???
People who have had an allergic reaction to gelatin, neomycin both of which are ingredients of the vaccine or any other component of the vaccine should not get the shingles vaccine as it can lead to serious reactions. It is best to consult an expert on immunology about the allergy testing and only after consulting a professional doctor with expertise and experience on vaccination issues can the decision of vaccinating or not vaccinating can be taken. Do take care and keep us posted.
Best of luck!
