Vaccine rates for young people entering school has been declining in recent years:
The rate of unvaccinated kindergartners in Maine continues to climb and is now the fifth highest in the nation, according to a U.S. Centers for Disease Control and Prevention report released Friday.
The percentage of Maine parents voluntarily opting out of vaccines for their children is alarming state public health officials who have been working to bolster immunization.
Nearly 800 public school kindergartners in Maine started the 2013-14 school year without receiving the required vaccinations for diseases such as whooping cough and measles because their parents opted not to immunize. That represents 5.2 percent of all kindergartners in the state, up from 3.9 percent the previous year.
This is in large part due to the anti-vax movement that has been steadily gaining ground since the 90’s. Indeed, although disgraced British doctor Andrew Wakefield had his 1998 study linking vaccines and autism debunked – no one ever reproduced his results, and it was no wonder since he outright made them up – he remains a hero of the anti-vax crowd.
One of the more favored canards of anti-vax quacks is to call herd immunity a myth. Do a quick search and one is liable to find any given quack claiming that herd immunity makes no difference to the health of a state. I recall reading some random anti-vax nobody argue that because vaccines are between 60-80% effective, even with 100% compliance, we could still see an epidemic. Of course, while he spoke of vaccines at-large in an intentionally general sense, he actually linked to CDC statistics on the flu vaccine. I guess it was a coincidence that he found it inconvenient to tell his readers that he was talking about one specific vaccine, huh? So is the high bar set by quacks.
At any rate, for herd immunity to be effective, there needs to be about a 95% vaccination rate. Of course, 100% would be the ideal because we’re talking about saving human lives, but with all the anti-government and anti-science kooks out there, 95% is actually a very achievable number that allows for some bumper space. Unfortunately, sometimes we see areas that fall well below that bumper space. For instance, when vaccine rates for whooping cough fell to 91% in California, communities there saw an outbreak in the disease. Thousands got sick and at least 10 infants died. What makes this all the more heart-breaking is that these infants were too young to be vaccinated, meaning they relied upon the herd immunity around them to remain safe. Anti-vax parents and the quacks they trust are at fault for these deaths. Frighteningly, Maine is on a similar path.
