If you’ve landed here wondering whether your kid needs an anthrax or smallpox shot at their next checkup, take a breath. They don’t. Neither of these vaccines is on the standard childhood schedule, and that’s not an oversight. Smallpox was officially wiped off the map back in 1980, the only human disease we’ve ever managed to eradicate. Anthrax is a totally different animal, a bacterial illness usually linked to livestock and contaminated soil, not something kids run into at daycare. So why does a parenting site even cover these? Because people ask, and because a few specific groups of adults do still need them.
Who Actually Gets These Vaccines
Anthrax vaccine is reserved for people with real occupational or military exposure risk. Think lab workers who handle anthrax cultures, certain members of the military, and people whose jobs involve handling animals or animal products where anthrax could turn up. It’s not given as a general precaution and it’s not something a pediatrician would ever bring up for a child. You can find the CDC’s current guidance on who qualifies for anthrax vaccination if you want the full breakdown.
Smallpox vaccine works the same way. Since the disease no longer exists in the wild, routine vaccination stopped decades ago. Today it’s mainly given to lab personnel who work directly with orthopoxviruses, some military personnel, and healthcare or emergency response workers who might be called on during a bioterrorism response or an outbreak of a related virus like mpox. It’s a niche vaccine for a niche group of adults, plain and simple.
It’s a bit like the situation with the plague vaccine, another shot that sounds alarming but really only applies to people in specific high risk jobs, not the general public and definitely not kids.
How They’re Given and What to Expect
Anthrax vaccine for pre exposure protection is a series of five shots spread over 18 months, followed by yearly boosters to keep protection going. If someone’s been exposed and needs it fast, there are shorter post exposure options, either three shots over four weeks or two shots two weeks apart, depending on which product is used. Side effects tend to be the usual stuff you’d expect from any injection, soreness at the site, some redness or swelling, maybe a headache or feeling tired for a day.
Smallpox vaccination looks different depending on which version someone gets. ACAM2000 is a single dose given with a special multiple puncture technique, and it leaves a distinctive blister that scabs over as the body builds immunity. JYNNEOS is gentler, given as two shots four weeks apart for someone getting it the first time, and it’s the preferred option for people who are immunocompromised. Common side effects include arm soreness, redness, fatigue, and sometimes a mild fever. ACAM2000 in particular needs careful aftercare since the live virus at the injection site can spread if it’s not covered properly.
Talking to Your Doctor
None of this is something to lose sleep over as a parent. If you’re not in one of these specific risk groups, this isn’t a vaccine conversation you’ll ever need to have for your family. And if you do work somewhere that puts you in scope, whether that’s a lab, the military, or emergency response, your employer or a doctor will walk you through what’s needed and when. Curious about the bigger picture of why kids get the shots they do? Our page on how vaccines work is a good place to start. As always, this is general information, not medical advice, so bring any specific questions to your pediatrician or your own doctor, who knows your situation best.
