A healthcare professional has 2 documented doses of MMR, but a post-vaccination measles titer is negative. The CDC recommends a 3rd dose of MMR for this person because their immunity will not be able to fight a measles infection.
The MMR is a vaccine that contains live “weakened” measles, rubella and mumps viruses and is usually given in two doses: the first, taken at one year of age, and the second, at 15 months.
With this information, we can conclude that a healthcare professional has 2 documented doses of MMR, but a post-vaccination measles titer is negative. The CDC recommends a 3rd dose of MMR for this person because their immunity will not be able to fight a measles infection.
