Smallpox vaccine scars are not very common nowadays. They are usually found on people over 40 years of age, especially those who received the Dryvax® or ACAM2000® smallpox vaccines. The smallpox vaccine is administered using a bifurcated (two-prong) needle, which makes multiple punctures in the skin to deliver the virus to the dermis. This causes a small, round bump (papule) to develop, which later turns into a fluid-filled blister. This blister eventually scabs over, leaving a permanent scar as it dries up. However, the scar may fade over time, and some people may opt for scar revision to reduce its appearance.

Smallpox scars are rare today, especially in younger generations
Smallpox scars are becoming rarer, especially in younger generations. This is because routine smallpox vaccination ended in the United States in 1972, and the disease was eradicated globally by 1980. As a result, only people over 40 are likely to have the smallpox vaccination scar, a dime-sized dent on their upper left arm.
The smallpox vaccine, containing a live version of vaccinia, a similar but less dangerous virus to smallpox, would cause an itchy, painful, and red skin lesion within three to four days of vaccination. This bump would fill with pus and then crust over to form a scab within a few weeks. This process would leave a permanent scar, which was a sign that the vaccine had been successful.
However, the formation of a scar is not guaranteed. If the vaccination spot does not develop a bump or blister, the immunization process is considered unsuccessful, and a repeat vaccination is recommended. Additionally, immunity from the smallpox vaccine begins to wane after three to five years, and certain individuals may require repeat vaccinations to maintain their protection.
Today, the smallpox vaccine is only administered to specific groups, such as certain military personnel and laboratory workers, who may be at higher risk of exposure. The development of new vaccines, such as JYNNEOS, which protects against smallpox and monkeypox without causing skin lesions or scarring, further contributes to the rarity of smallpox scars in younger individuals.
While smallpox scars are becoming less common, it is important to note that they are harmless and can be treated with scar creams or "skin camouflage" products to reduce their appearance if desired.

The scar is a sign that the vaccine worked and your body built up its immune defences to keep you safe
The smallpox vaccine is no longer routinely administered, so it is unlikely that younger people will have a smallpox vaccine scar. The last routine smallpox vaccinations were administered in the United States in 1972, and smallpox was eradicated globally by 1980. As a result, only people over 40 years of age are likely to have the characteristic dime-sized smallpox vaccine scar on their upper left arm.
The smallpox vaccine scar is a sign that the vaccine worked and your body built up its immune defences to keep you safe. The vaccine contains a live version of vaccinia, a virus similar to smallpox but less dangerous. After being vaccinated, most people developed an itchy, painful, red skin lesion within three to four days. The bump later becomes a larger blister that leaves a permanent scar as it dries up. This controlled infection forces your immune system to defend your body against the virus.
The scar is a useful indicator that the vaccination has been successful, a process called "a take". Healthcare providers check for signs of a take within the first week or so after vaccination. They look for a blister forming, which indicates that your body is responding as it should. If these signs are absent, you may need to be vaccinated again.
The smallpox vaccine usually left a distinctive round or oval-shaped scar that may look deeper or lower than the surrounding skin. The scar may have more irregular edges compared to other vaccine scars. However, the JYNNEOS vaccine, approved by the FDA in 2019 to protect against smallpox and mpox (monkeypox), does not cause skin lesions or scarring.

The scar is a dime-sized dent on the upper left arm
Smallpox vaccine scars are not very common nowadays, and you would most likely only have one if you are over 40 years old. The scar is a dime-sized dent on the upper left arm, which is a sign that the vaccine was successful and that your body built up its immune defences to keep you and others safe. The scar is typically round or oval-shaped and may look “deeper” or lower than the surrounding skin.
The smallpox vaccine is administered using a technique called the puncture method, which requires a bifurcated needle with two prongs to deliver the vaccine to the proper depth in the skin. The vaccine contains a live virus, creating a controlled infection that forces your immune system to defend your body against the virus. This process causes a sore and itchy bump that later blisters and becomes a permanent scar.
If you received the smallpox vaccine but don't have a scar, it's possible that the vaccine didn't "take." Healthcare providers typically check for signs of a "take" within the first week after vaccination, looking for a blister forming as a sign of a successful immune response. If these signs aren't present, a repeat vaccination may be recommended.
The smallpox vaccine was once a routine part of childhood vaccination in the United States, but routine vaccination ended in 1972, and smallpox was globally eradicated in 1980. Now, the smallpox vaccine is only given to certain groups, such as military service members and laboratory workers.
If you have a smallpox vaccine scar and are interested in reducing its appearance, you can consult a dermatologist for treatment options, including the use of sunscreen, moisturizer, and scar cream to help the scar heal and become less noticeable.

The smallpox vaccine is no longer routine, now only given to certain groups
The smallpox vaccine was first developed in the late 1700s, with British physician Edward Jenner demonstrating that an infection with the mild cowpox virus conferred immunity against smallpox. Cowpox served as a natural vaccine until the modern smallpox vaccine emerged in the 20th century. From 1958 to 1977, the World Health Organization (WHO) conducted a global vaccination campaign that eradicated smallpox, making it the only human disease to be eliminated. Smallpox was declared eradicated by the WHO in 1980, and routine smallpox vaccination ended in the United States in 1972.
Due to the success of the vaccine, smallpox no longer occurs anywhere in the world, and the public is not routinely vaccinated against the disease. The smallpox vaccine is now only recommended for specific groups, such as certain military personnel and laboratory workers who work with related viruses. Smallpox has been identified as a potential weapon in bioterrorism attacks, so the vaccine is still being produced to guard against this threat.
The smallpox vaccine is given using a bifurcated (two-pronged) needle that is dipped into the vaccine solution and then used to prick the skin 15 times in a few seconds. This technique creates a controlled infection, forcing the immune system to defend the body against the virus. The vaccination site usually develops a red and itchy bump within three to four days, which becomes a large blister that fills with pus and eventually dries up, leaving a small scar.
The smallpox vaccine scar is typically a small, round or oval-shaped mark on the upper arm, about the size of a dime. It may appear lower than the surrounding skin with irregular edges. The scar is a sign that the vaccine was successful and that the body built up its immune defences. However, the formation of a scar is not guaranteed, and the absence of a scar does not necessarily indicate that the vaccine was ineffective.
While smallpox vaccination has been highly effective in eradicating the disease, it is important to note that there have been reports of serious adverse effects, including potential heart complications and eye-related issues. As a result, the vaccine is currently only recommended for specific high-risk groups, and individuals with certain heart conditions or eye diseases are advised to avoid it.

The scar can be treated with sunscreen, moisturiser, and scar cream
Smallpox vaccine scars are becoming less common, and you are unlikely to have one if you are from a younger generation. Typically, only people over 40 years of age have a smallpox vaccination scar, a dime-sized dent on their upper left arm. The scar is a sign that the vaccine worked and that your body built up its immune defences.
If you have a smallpox vaccine scar, you can treat it with sunscreen, moisturiser, and scar cream. Sunscreen with an SPF of 30 or more will help protect the scar, as the skin in that area may be more sensitive. You should also keep the scar covered when you are in the sun for at least a year. Moisturising the scar can help make it softer and flatter. Silicone products, such as silicone sheets and gels, can keep your scar moisturised and aid the healing process. Finally, a dermatologist might recommend a scar cream to help the scar heal and become less noticeable.
If you are concerned about the appearance of your smallpox vaccine scar, you can talk to a dermatologist about other treatment options.
It is important to note that the smallpox vaccine is no longer routinely administered. Now, it is only given to certain groups, such as specific military service members and laboratory workers.
