Six Signs and Symptoms of Vaccine Injury


Vaccine injuries can often present themselves with a number of different symptoms. Some of these side effects are more acute than others. It is essential to get prompt medical attention when there is any sign of vaccine injury. Patients should be well-informed so that they know what to look for because they often are not expecting to suffer complications from vaccines and may have difficulty associating the injury with the vaccine.

Pain and Swelling

This will likely be the first sign of any vaccination injury. Especially when it comes to shoulder injuries after vaccination, this symptom of the injury may become apparent within hours after the injection. Patients may experience soreness and redness at the injection site. Many vaccinations will have some sort of discomfort in the immediate aftermath of the injection. However, the pain and swelling will soon subside, often within hours.

The problem occurs when the pain and swelling do not go away at all. In some cases, these symptoms may get even worse as more time passes. If the swelling persists past several days and worsens, you should seek immediate medical attention. When this happens in children, you may not know the exact issue since the infant cannot communication, but severe crying after vaccination is a sign that they are feeling pain.

Difficulty Breathing

If one is experiencing this after vaccination, they must seek immediate medical attention. This is a sign that the patient is experiencing an anaphylactic reaction to an injection. Anaphylactic shock occurs when the body releases a chemical to counteract a substance to which they are allergic.

Some people are allergic to part of the vaccination. Each vaccine contains a number of substances, some of which act as a filler or stabilizer. Patients may not realize that they have an allergy to an ingredient of a vaccine until they experience it for the first time. Certainly, parents will not know of their infant’s allergy the first time that the child received a vaccination. There are other severe allergic reactions to a vaccination that can pose a danger. Patients may develop hives or their mouth may swell.

High Fever

It is relatively common for a patient to run a low-grade fever after a vaccination. However, when this fever becomes elevated, it is a sign that there is something more serious. In most cases, the fever will start approximately 12 to 24 hours after the vaccine is administered and can last for two or three days. Generally, a fever under 102 degrees is tolerable and not anything alarming.
However, when the fever exceeds 102 degrees, this is a dangerous sign. In most cases, acetaminophen or ibuprofen can help control the fever. However, you need to be careful when giving these to children and do so under the supervision of a physician. If there is a high fever, you should seek immediate medical attention to rule out anything more serious. Given that many vaccinations introduce a live virus into the body, patients must be careful when their fever unreasonably elevates.

Seizures after a vaccine are rare, they are incredibly dangerous when they occur. While the rate of seizures in children is generally one in every 3,000 vaccinated children, seizures present serious health risks. Most children will recover from their seizures. Moreover, vaccines will generally not cause seizure disorders but may cause isolated incidents.

Seizures generally occur when a patient already has an elevated fever. The seizure will last for one to two minutes, and the patient will generally recover from them. While seizures after vaccines are not common, the risk of a seizure increases by 200 to 500 percent the day that the patient receives a live virus vaccine.


Some vaccinations have a slightly elevated risk of a disease called Guillain-Barre Syndrome. This is a neurological condition where the body’s immune system attacks the central nervous system. GBS starts with numbness and weakness in the extremities. This numbness may be felt starting several days after the vaccination is given. In some cases, this side effect may manifest itself several weeks after the vaccination. The numbness is a sign of neurological issues that have been caused by vaccination.

Numbness and tingling is a sign that the patient needs immediate medical attention. The weakness can also lead to involuntary motion in the extremities.


Patients can experience skin irritation after receiving a vaccination. In minor cases, the rash is localized and is relatively mild. However, in some more severe instances, the rash can either be dark red or spread beyond the injection site over the body. The more severe cases require immediate medical attention. This is more likely to happen in some vaccines such as the measles, mumps and rubella vaccine. Infants are more likely than adults to develop a rash because they have more sensitive skin. In very rare cases, patients can develop a chicken pox-like rash on their body from the vaccination.

When you have experienced a vaccine injury that is serious, you may be able to obtain compensation from the Vaccine Injury Compensation Program. This is a fund administered by the federal government that is paid for by taxes that are assessed on each individual vaccination. You can file a claim for compensation with the VICP and it will go through its own unique informal process that is easier than a full-fledged lawsuit.
