Third dose of measles vaccine?

<p>My 20-year-old son just went for his annual physical. His doctor said he should get a booster shot of measles vaccine. DS did have the two doses of MMR at the recommended times (soon after his 1st birthday and again when he was five years old). But his lab tests apparently indicate that his immunity is not what it should be. (Specifically, the Measles AB,IGG Index was 0.70, when it should be >0.99, and the Measles AB,IGG INTP was Negative, when it should have been Positive.)</p>

<p>Has anyone else dealt with this by getting a measles vaccine booster, after having two doses of MMR?</p>

<p>My kids both had MMR boosters prior to going to college. I actually think this was required by their schools. There had been a number of measles outbreaks, and I thought it was determined that an additional booster was necessary.</p>

<p>I hadn’t needed one, but i think i got the booster when i was… 14? or so. I did have to get a new tetnus and Mengincocal vaccine (i think).</p>

<p>Our older kids needed a booster (required) before going to college. There were several outbreaks of measles on various campuses over the past 15 years or so. They also had to get the meningitis vaccine.</p>

<p>Sodium free, I don’t think my kids have had their titers checked, was there another reason the doc did this?</p>

<p>Youngest didn’t have many childhood vacinnes at regular time for several reasons, but she went to Africa when she was 17 and India when she was 18, so she is all caught up, and then some.
Good reminder about the MMR however, my oldest had her shots in childhood, but she is also a teacher so she needs a booster.
( :frowning: she also would faint when she would get TB tests to work at the zoo, so I don’t imagine that she has scheduled her appt)</p>

<p>I know a young med student who had to repeat the entire MMR series and get another hepatitis B (I think it was B…) because his titers were so low. He’d gotten all the recommended vaccinations growing up and wouldn’t have known he had no immunity if he hadn’t been required to have the blood work as a part of his med school physical.</p>

<p>Kinda scarey for those of us who haven’t had such blood work…Maybe we’ve lost our immunity as well??</p>

<p>I got the blood work test done because i had somehow lost my shot records. Two birds one stone :slight_smile: My mom wanted me to be completely up to date.</p>

<p>However, to this day, i point blank refuse to get the flu shot.</p>

<p>Thanks to everyone for your replies.</p>

<p>emeraldkity4, I don’t really know why the doctor had DS’s titers checked. This was just a routine annual physical, not related to school. This is a new doctor for DS, as he finally graduated from this pediatrician. I’m thinking maybe this doctor just checks titers routinely for all patients, although I’m not sure. In any case, the doctor gives his patients a copy of all the lab test results, and the MMR titers were just one of many results, including routine things like cholesterol, etc.</p>

<p>I did a google search on this topic, and after posting my question, I found [a</a> Q&A](<a href=“http://www.immunize.org/askexperts/experts_mmr.asp]a”>Ask the Experts: Measles, Mumps, and Rubella (MMR) Vaccines) on the Immunization Action Coalition website (IAC appears to be related to the CDC, according to their [About</a> Us](<a href=“http://www.immunize.org/aboutus/]About”>About Immunize.org - Mission Statement - Publications) page) which suggests that a booster is not needed, and that the titer test might be wrong:</p>

<p>"[Q] Would you consider a person with 2 documented doses of MMR vaccine to be immune even if their serology for 1 or more of the antigens comes back negative?</p>

<p>“[A] There is no ACIP recommendation for this situation. A negative serology would more likely be the result of an insensitive test than of a true vaccine failure. No more doses are necessary.”</p>

<p>The website gives [this</a> link to the AICP recommendations on MMR](<a href=“http://www.cdc.gov/mmwr/PDF/rr/rr4708.pdf]this”>www.cdc.gov/mmwr/PDF/rr/rr4708.pdf).</p>

<p>I’m not really sure, though, why they say that a negative serology would more likely be due to an insensitive test. I realize that there are possible negative side effects from any immunization, but I think I would be inclined to assume the serology results are correct. In the end this is up to DS and his doctor, but I think that I will tell him what I’ve learned, from the IAC website and all your responses, and recommend that he follow his doctor’s advice to get the booster.</p>

<p>Thanks again!</p>

<p>interesting information, SF. My young friend has no choice but to repeat the MMR and get a Hep B booster. His med school requires it.</p>

<p>I’m wondering what side effects might result if the blood work is wrong…</p>

<p>I have asked about that Beil, I’m not in the medical profession so the explanation went over my head, but it didn’t sound like there are detrimental effects.</p>

<p>

<p>Slight extra cost due to the additional dose, if the person was previously vaccinated but the test incorrectly indicated low immune response (i.e. person actually has good immune response).</p>

<p>It is understandable that a medical school would want students to be fully vaccinated, since they will eventually be working around sick people, infected blood, etc…</p>

<p>We traveled to a third world country and had to show evidence of current MMR OR evidence we had these illnesses prior to a certain year.</p>

<p>I had evidence of my mumps vaccine and my having measles in the 1950’s epidemic…and rubella also.</p>

<p>DH had no evidence and had the titer done. His mother swore he had mumps, but he showed no immunities to measles, mumps, or rubella, so he had the shot.</p>
