Actually it is good to be vaccinated even if you have already had a disease. This confers greater immunity than the infection or just the vaccine.
Whether or not the vaccine or natural immunity is better protection isn't as clear as suggested either, generally the vaccines will give more reliable resistance.
"Natural immunity can be spotty. Some people can react vigorously and get a great antibody response. Other people don't get such a great response," says infectious diseases expert Mark Rupp, MD. "Clearly, vaccine-induced immunity is more standardized and can be longer-lasting."
