Running the numbers: US vaccination rates up ever so slightly; New Jersey way below national average

Earlier today, the CDC posted the results of its 2010 National Immunization Survey, which monitors vaccination coverage for kids between 19 and 35 months of age. The numbers are encouraging:

Nationally, vaccination coverage increased in 2010 compared with 2009 for ≥1 dose of measles, mumps, and rubella vaccine (MMR), from 90.0% to 91.5%; ≥4 doses of pneumococcal conjugate vaccine (PCV), from 80.4% to 83.3%; the birth dose of hepatitis B vaccine (HepB), from 60.8% to 64.1%; ≥2 doses of hepatitis A vaccine (HepA), from 46.6% to 49.7%; rotavirus vaccine, from 43.9% to 59.2%; and the full series of Haemophilus influenzae type b (Hib) vaccine, from 54.8% to 66.8%.

Coverage for the MMR vaccine, the polio vaccine, and the varicella (or chickenpox) vaccine are all above the national targets  of 90% — which is obviously wonderful news. It’s particularly nice to see the uptick in children getting one or more dose of MMR, which reverses what happened between 2008 and 2009, when there was a decrease from 92.1 percent to 90.0 percent.

I’d guessing that a year from now, we’ll learn that MMR rates continued to rise in 2011: It’s hard to imagine how the nationwide measles outbreaks would have any effect other than further reinforcing the importance of getting your shots.

The data that jumped out at me was in the state-by-state breakdown. Only 10 states have MMR rates below 90 percent — and two of those (New York and New Jersey) are in the Tri-State area. New Jersey’s 86.1 figure was particularly eye-popping: the only other state below 87 percent is Montana.

    I see that 95% had received three or more DTP/DT/DTaP in 2010, same as in 2009. Guess they’ll have to stop blaming the pertussis outbreak on falling vaccine rates.

    Great news!

  3. Thomas says:

    Good news for us parents and our children (except for those in NY and NJ, of course) – we’re making progress!

  4. Andrew says:

    Sounds like good news, particularly for people with medical conditions that preclude vaccination.

    “New Jersey’s 86.1 figure was particularly eye-popping: the only other state below 87 percent is Montana.”

    But how can this be? New Jersey has the highest reported estimated autism prevalence in the U.S.. What’s to become of the vaccine hypothesis?

    In case any reader is wondering–the above is not serious. But I expect that if there were a high MMR uptake in New Jersey, we’d be hearing about it loud and clear from those promoting vaccine-causation.

  7. Andrew says:

    Twyla: The distribution of the unvaccinated matters. When the distribution is random, it is likely that the unvaccinated will be surrounded and protected by the vaccinated people around them. When the unvaccinated cluster together, outbreaks that spread rapidly will occur. The recent pertussis outbreaks occurred in areas with such pockets of unvaccinated people.
