The federal government may try to take action if states don't tighten their vaccine exemption laws and measles continues to spread in sections of the U.S., FDA Commissioner Scott Gottlieb tells Axios.
Driving the news: Overall case numbers of measles remain low in the U.S. but the disease is growing in areas of high non-vaccination rates. Some states like Washington are considering tightening their exemptions even as they continue to face a more organized anti-vaccination movement.
"It's an avoidable tragedy," Gottlieb, who says he's usually a proponent of state rights, tells Axios. "Too many states have lax laws."
Background: The highly contagious disease can only be controlled if there's a large vaccination rate in the population, which the World Health Organization says should be 93%–95% of people.
- States are allowed to adopt their own rules over what types of exemptions are allowed for vaccines. All of them allow exemptions for medical reasons, but many also provide exemptions on religious and/or philosophical grounds.
- These pockets of unvaccinated people are transmitting measles in the U.S., which is particularly dangerous to those who can't get vaccinated, including babies under 12 months and people with susceptible immune systems.
- Gottlieb says the vaccine is one of the most effective ones (97% with 2 doses) created so far, and for one of the most contagious viruses.
- Measles can cause various complications, including pneumonia, brain damage and sometimes death, and it has been linked to longer term immune problems.
What's happening now
In Washington state, the number of confirmed cases has more than doubled since Gov. Jay Inslee declared a state of emergency on Jan. 25, to 54 as of Feb. 13.
- Clark County, where a majority of the Washington cases are located, reported a 70% MMR vaccination rate for 19–35 month olds. But since the outbreak, there was an almost 450% increase in vaccination rates in January compared with the same month the prior year.
"It's a self-inflicted wound," says Peter Hotez, dean at Baylor College of Medicine who published a study last year showing possible U.S. "hotspots" of measles due to vaccine exemptions, that he says is already proving to be true.
- Pro-vaccination groups are "losing the battle" to anti-vaccination groups, who've been very active on social media and forming at least one PAC to promote their message, he says.
The other side: Barbara Loe Fisher, co-founder and president of the nonprofit National Vaccine Information Center often labeled as anti-vaccination, tells Axios that 100 cases of measles in a population of 320 million "is not a public health emergency."
- "[It] should not be used to justify eliminating the legal right to exercise informed consent to vaccination, which is protected by the inclusion of flexible medical, religious and conscientious-belief vaccine exemptions in public health laws," she says.
