The headline number from Thursday’s federal health advisory is that rabies inquiries to the Centers for Disease Control and Prevention rose 17 percent across July and August compared with last summer.
The number that actually explains the advisory is a different one: use of rabies immune globulin is up 76 percent, more than four times the rise in exposures, which is not what a wildlife surge looks like.
Nearly every version of this story that ran in the last two days told readers to avoid wild animals and vaccinate the dog. Useful advice, and not what the CDC wrote. The Health Alert Network advisory issued September 10 is addressed primarily to clinicians, and roughly half of it is a list of ways emergency rooms and urgent care clinics are administering rabies treatment incorrectly. At least eight state health departments reported increased use of post-exposure prophylaxis, administration errors, or both. The story here is not that more Americans are meeting rabid animals. It is that the system that treats them is fumbling a procedure that has to be done right the first time.
The Errors the CDC Named
Post-exposure prophylaxis, or PEP, is close to 100 percent effective when it is given promptly and correctly. The “correctly” is doing a lot of work. The advisory lists the mistakes being reported, and they are not subtle:
- Injecting the vaccine into the buttock instead of the deltoid, where absorption is reliable
- Failing to infiltrate human rabies immune globulin into and around the wound itself
- Mixing immune globulin and vaccine in the same syringe or the same anatomical site
- Leaving out immune globulin when it is required
- Giving immune globulin to people who were already vaccinated and do not need it
- Misclassifying a patient’s vaccination history
- Using incorrect vaccine schedules
- Restarting the whole vaccine series when there was no reason to
Read that list as a clinician-training document and it is mundane. Read it as a patient and it is alarming, because several of those errors are invisible at the time. A person who gets the vaccine in the wrong muscle walks out believing they are protected. A person who should have received immune globulin and did not walks out believing the same thing. Rabies is nearly always fatal once symptoms appear, and there is no second look.
The utilization figures point the same direction. According to pharmacy data cited by the agency through September 2, use of the two licensed rabies vaccines rose an estimated 33 percent year over year and use of the two immune globulins rose 76 percent, against that 17 percent increase in exposure inquiries. Some of the gap is real: mass exposure events inflate immune globulin demand quickly. North Carolina alone recommended shots for more than 260 people after three baby goats at a mobile petting zoo tested positive, having been bitten by a rabid skunk. But a four-to-one gap between treatment given and exposures reported is also consistent with a second explanation the CDC is too polite to state directly, which is that a meaningful share of these doses should never have been given, and some that were given were given wrong.
Why “When in Doubt, Give Everything” Is Not Free
There is a tempting clinical instinct here: rabies kills, the treatment works, so err toward giving it. Roughly 6 million animal bites are reported in the United States each year, about 100,000 people receive PEP, and fewer than 10 people die of rabies annually. By that arithmetic, over-treatment looks like cheap insurance.
It is not cheap. Immune globulin is dosed by body weight and is the expensive component, which is how a full course routinely lands in the thousands of dollars and occasionally somewhere absurd. KFF Health News documented a biologist billed $48,512 after a cat bite for a treatment that typically runs about $3,000, and a tourist who owed nearly $21,000 after a bat encounter. An unnecessary immune globulin dose is not a harmless precaution. It is a five-figure event in somebody’s life, delivered by a clinician who did not make the phone call that would have settled whether it was indicated.
That call is the actual recommendation buried in the advisory. The CDC wants clinicians to consult their state or local health department on local rabies epidemiology before deciding, because whether the raccoon in your county carries rabies is a local fact, not a national one. It also wants immediate wound washing with soap and water, a real risk assessment rather than a reflex, and verification of vaccination history before anything is injected.
Our View: Treat This as a Delivery Failure, Not a Wildlife Story
We think the framing most outlets chose does readers a disservice, and the CDC’s own communications team helped it along by leading its public statement with animal activity rather than with clinical practice. The wildlife trend is the context. The failure is in American emergency departments, where a treatment with a fixed, published schedule is being improvised often enough that eight states flagged it in two months.
Responsibility sits in three places, and it is worth naming them. Hospital systems own the fact that a time-critical protocol is not at the bedside where the decision gets made. State health departments own the fact that “call us” is only useful if somebody picks up at 11 p.m. on a Saturday, when most bites turn into decisions. And the CDC owns the messaging choice: an advisory whose substance is eight clinician errors should not have been packaged in a way that produced two days of “beware of bats” coverage.
What should happen is not complicated. Every emergency department should have the current rabies schedule available at the point of decision the way it has stroke and sepsis protocols, states should publish a 24-hour rabies consultation line and staff it, and health systems should audit a sample of the PEP they gave this summer against the advisory’s error list and report what they find. The agency’s guidance carries weight only if the people receiving it treat it as operational, and it lands at a moment when federal vaccine messaging has been publicly contested all year, which makes clear, boring, procedural advice more valuable rather than less.
If you were bitten or scratched this summer and got the shots, you are almost certainly fine. The odds of any individual error are low, and the treatment is forgiving of most of them. But you are entitled to know that the federal government just told your doctor, in writing, that a lot of doctors have been getting this wrong, and to ask which muscle the needle went into.
