Vaccininum is a homeopathic remedy made from cowpox vaccine lymph. That is the fluid once used to give smallpox shots. Its Latin name is Vaccinia virus, and some labels call it Cowpox vaccine nosode.
A nosode is a homeopathic remedy made from a disease product or from a vaccine. The starting fluid is sterilised, then watered down step by step and shaken between steps. At 30C, the strength most often sold, no molecule of the source is left in the pill.
Homeopaths have given it for fever, rash or tiredness said to come on after a smallpox shot. Here is the plain verdict: it is not a vaccine, and trials do not show it works better than a dummy pill (placebo). Long use in a tradition is not proof that something works, and that holds for this remedy too.
There is no known way for it to act on the body, because at 30C nothing of the source is left.
Homeopathy works from an idea called "like cures like". A substance that causes certain signs in a well person is meant to ease those same signs in a sick one. Makers believe the shaking step leaves an imprint in the water after the source is gone.
That idea does not match what we know about chemistry or the body. No test has shown such an imprint. When trials give real pills and dummy pills, people do about the same on both.
Small round pills you let melt under the tongue. This is the most common form.
Other forms are liquid drops, single-dose paper tubes of pills, and small granules for children. Strengths on the label run from 6C and 12C up to 30C, 200C and higher. The larger the number, the more times it has been watered down.
Nosodes came into homeopathy in the 1830s, through Constantine Hering. He prepared remedies from disease material and from vaccine fluid.
Vaccininum appears in homeopathic books from the 1800s onward, mostly for complaints said to follow a smallpox shot. It has always been a minor remedy, not a main one. It has no use outside homeopathy.
See a doctor if a fever goes above 39C, lasts more than three days, or keeps coming back. Get help the same day for a rash that spreads fast, a stiff neck, bad headache, a lot of pain, or a shot site that is hot, oozing or growing.
Call emergency services straight away for trouble breathing, swelling of the face, lips or throat, a fit, confusion, or a rash that does not fade when you press a glass on it.
Also talk to your doctor before you use this if you are due a vaccine, or if anyone has told you a nosode can take a vaccine's place.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Vaccininum is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
