Staying out of an emergency room
The Vaccine Questions That Come Up in an Emergency Room
Published September 10, 2026 · 5 min read

We are not a vaccination clinic, and your own clinician is the right place
for routine immunisation. But a handful of vaccine questions arrive here
constantly, usually attached to an injury, and two of them are time-critical.
The urgent one first: if a bat has been in a room with a sleeping person, a
young child, or anyone who cannot reliably say whether they were bitten, that is
treated as a possible rabies exposure — even with no visible bite. Come in.
Rabies is effectively always fatal once symptoms begin, and it is entirely
preventable beforehand. This is not a wait-and-see.
A bat in the room is urgent
If anyone cannot reliably say whether they were bitten, that is time-critical.
Two of these are time-critical
They usually arrive here attached to an injury, which is why this page exists.
If you are unsure, come in
This list is not exhaustive and you are not expected to diagnose yourself.
Rabies, because Arizona is not a low-risk state for it
Bats, skunks and foxes carry rabies here, and bats are the exposure that
catches people out. The reason is specific:
A bat bite can be too small to see and too slight to feel. So the standard
approach does not depend on finding a wound. Any of these is a reason to be
seen today:
- A bat found in a bedroom where someone was asleep
- A bat in a room with a young child, or with anyone who could not tell you
what happened - Any direct contact with a bat, however brief
- A bite or scratch from a skunk, fox, coyote, or any stray or wild mammal
- A bite from a pet whose vaccination status is unknown
What to do: wash the area with soap and running water for several minutes —
which genuinely reduces risk — and come in. Do not try to catch or kill the
animal yourself, and do not handle a dead bat with bare hands. If it can be
safely contained by animal control, that helps.
And do not let embarrassment cost you this. "There was a bat in the room but
I do not think it touched me" is exactly the sentence we want to hear, because
it is the one the guidance is written for.
Tetanus, which we ask about every single time
Every wound visit includes the question "when was your last tetanus booster?"
and almost nobody knows the answer.
Adults need a booster roughly every ten years, and the questions that matter
here are whether you are within that window and how dirty the wound is.
Wounds where it matters most: anything from soil or gardening, puncture
wounds, animal bites, burns, crush injuries, and anything contaminated with
dirt, rust or manure. Stepping on something in a yard is the classic.
The useful thing you can do today: find out when you last had one and put it
somewhere you will find it. A photo of your immunisation record on your phone
answers a question that otherwise costs guesswork in the middle of a wound
visit.
The ones whose complications we see
We do not give these here, and we do see what happens without them. That is the
only reason they are on this page.
- Influenza, annually. The pneumonia and the cardiac events that follow flu
in older adults are a genuine part of our winter. - COVID-19, per current guidance for your age and health.
- Pneumococcal, which reduces the severe pneumonia we admit and transfer.
- Shingles, for older adults. Shingles itself brings people here, and the
nerve pain afterwards can last months.
When a rash is an emergency - RSV, for older adults and in pregnancy, per current guidance.
- Tdap in pregnancy, which protects a newborn before they can be immunised.
Whether each applies to you depends on your age, your health and current
recommendations — which change. That is a conversation with your own
clinician, and this page deliberately does not include a schedule.
If you are due, and the honest limit of what we can help with
Ask your primary care clinician or a pharmacy. Most routine adult vaccines
are available at pharmacies without an appointment, which is usually the fastest
route.
What we can do is treat the wound in front of us and tell you whether the
tetanus question needs answering today. What we cannot do is be your
immunisation service, and pretending otherwise would be the same error as
implying we provide primary care.
ER or urgent care
What happens when you arrive here
- A physician sees you — board-certified, every visit, at every hour.
- The wound assessed and treated, including cleaning and closure where
needed. - The tetanus and rabies questions asked and answered for the injury in
front of us. - Laboratory and imaging on site where a wound may be deeper or more
contaminated than it looks. - Monitoring for up to 24 hours where a wound infection needs watching
rather than admitting.
If rabies post-exposure treatment or a specialist is needed and we cannot
provide it here, we arrange it. We are an emergency room, not a hospital, and
for a possible rabies exposure getting into the right pathway quickly is the
whole point — so tell us at the desk rather than waiting to be asked.
