Individuals receiving the Diphtheria, Tetanus, Pertussis (DTaP, DTP, DT, Td, or TT) vaccine may experience shoulder pain as a potential side effect. This pain typically arises due to improper injection technique, leading to SIRVA. Symptoms can include sharp or dull pain in the shoulder, restricted movement, and discomfort that can emerge within hours to a few days post-vaccination. Those affected may seek compensation through the VICP for their injuries. Consulting a specialized Diphtheria, Tetanus, Pertussis injury lawyer can provide guidance on the claim process.
