Onset of the rash

Shingles vaccine

In rare cases, a rash that develops after the shingles vaccine is given can indicate a complication such as an allergic reaction or an infection. The indications of an allergic reaction usually include nausea, chest tightness or pain, vomiting, difficulty breathing, diarrhea, facial swelling, anxiety or dizziness.

Those who were given the shingles vaccine should report all forms of rashes that developed within 42 hours after the vaccine was administered. Individuals who experienced rashes on the injection site developed 2-3 days after the vaccine was given. Others who experience rashes in other parts of the body usually appeared more than 2 weeks after the vaccine was administered.

How long the rashes last?

The rashes that developed on the injection site typically resolve within 5 days unlike from the rashes that developed on other parts of the body which resolves within 18 days. The rashes that develop on other parts of the body are likely to reflect vaccine failure rather than a side effect of the vaccination. Take note that in all but a few cases, the laboratory tests show that the cause of the rash was in reality shingles but not the strain of the virus that was utilized in the vaccine.

Frequency

It is important to note that less than 1% of cases who received the shingles vaccine developed a rash. The rashes are more likely to occur among individuals 60-69 years old than those over 70 years old.

Complications

In rare cases, a rash that develops after the shingles vaccine is given can indicate a complication such as an allergic reaction or an infection. The indications of an allergic reaction usually include nausea, chest tightness or pain, vomiting, difficulty breathing, diarrhea, facial swelling, anxiety or dizziness. The symptoms of infection include fever or discharge of the injection site. Those who suffer from these symptoms must consult a doctor for instructions or simply bring the individual to the emergency department at the nearest hospital.
