One in three two-year-olds in United States have not received all recommended childhood vaccines, study finds

Approximately 34 percent of children in the United States do not receive all doses of vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) by age 2, according to a new study by researchers at RTI Health Solutions, a business unit of RTI International.

This is consistent with findings reported by the Centers for Disease Control and Prevention. The ACIP recommends most children receive a series of routine immunizations, consisting of 19 doses of vaccines administered at age-specific intervals between birth and age 2 to protect against 11 diseases.

The study, published in press in Vaccine, used data from the 2012 National Immunization Survey, an annual survey conducted by the CDC, to examine vaccination coverage among a nationally representative sample of nearly 12,000 2-year-olds in the United States. Researchers estimated the proportion of children who completed the ACIP recommended number of doses by 8, 18 and 24 months of age (completion rates); and whether each dose was administered at age-appropriate times between birth and 24 months (compliance rates).

  • What is going on? Is this as the result of the negativities of religious nut cases, or those of Andrew Wakefield?

    I’m probably only still alive because of scientific advances such as this; we seem to be going backwards!

    I blame god! I mean, just read the old testiment and the qur’an; we’ve been set-up!

    I’m not sure if it’s religious nuts or new agers or a combination of all these. Wakefield did much damage by linking vaccination with autism and that scared the hell out of people. Jenny McCarthy the mental midget also did much harm this way. I think she has a child who is on the autism spectrum and made public announcements that he developed autism caused by vaccinations. Americans pay close attention to scientific claims made by playboy bunnies. Want to have the attention of Americans riveted upon you? Wear some big white floppy ears and a giant cotton ball on your bum.

    As our herd immunity drops more and more I’m very worried that the pathogens will have their way with us. Young moms here have never seen how bad measles, whooping cough, tetanus etc really are. But everyone knows someone on the autism spectrum. This is very short sighted and it really won’t end well. I’m worried.

  • Western states had the lowest rates of completion and compliance. Southern states had the highest completion rates, yet compliance rates were moderate, indicating that children were receiving vaccines late, but catching up by age 2. The most undervaccinated state was Alaska where 55 percent of children completed all recommended doses by age 2; whereas, Mississippi had the highest completion rate at 77 percent.

    I would say woo rather than religion reading the above. Still, 19 doses in 2 years may be something many people can not do financially or do withing the time constraints. Are all these doses generally free? Do two working parents have the time to make all 19 doses in 2 years?

    Some other factor aside from religion and woo working here?

  • People don’t understand the selfishness of refusing vaccination. There are people such as newborns who can’t get vaccinated. They rely on everyone else to vaccinate to protect them by herd immunity.

    Refusal to vaccinate is a form of attempted murder.

    They rely on everyone else to vaccinate to protect them by herd immunity.

    Especially with urban lifestyles where large crowds gather and meet in places with restricted ventilation, such as buses, trains aircraft, shops, schools, bars, theatres, stadia, etc.

  • I think you’re pretty much spot on. In the western states its woo and a bunch of hippy dippy BS. In the south it’s a combination of poverty hindering compliance since missing work means losing your job and a lot of rural docs aren’t open on Saturday or Sunday (although most docs will do house calls for severe illness in my experience growing up in a rural area). Also, in rural areas a trip to a bigger city where you can get the vaccines on your day off is often a 30 or 40 mile drive and vaccines while cheap aren’t free. Ultimately though, the southern states’ completion rate is higher for a lot of reasons, religion over woo is a big one as most religions are pro vaccine because apparently they consider choosing to let your children die due to a preventable or curable illness to be a sin somewhat like murder and thus evil.

    Frankly if we wanted to get the compliance rates up we’d have vaccine programs in the churches in the south since a huge portion of the rural poor (those who have poor compliance but good completion) are in the pews each week. I mean it’s not like it’s hard to teach a couple of community members how to give injections and I don’t mind if religion gets used as a tool to accomplish an important health goal.
