If a vaccine is administered too high in the shoulder, it can lead to a rare complication called Shoulder Injury Related to Vaccine Administration (SIRVA). This occurs when the injection is given too close to or within the shoulder joint.
Understanding SIRVA
SIRVA isn't a reaction to the vaccine itself, but rather a result of how the vaccine was administered. The deltoid muscle, located in the upper arm, is the ideal injection site. When the needle is inserted too high, it can impact the structures of the shoulder joint.
Symptoms of SIRVA
- Shoulder pain: This is a primary symptom that can be quite severe.
- Restricted range of movement: Difficulty moving the arm and shoulder may be experienced.
Diagnoses Associated with SIRVA
According to the provided reference, specific diagnoses related to SIRVA include:
- Bursitis: Inflammation of the fluid-filled sacs (bursae) that cushion bones, tendons, and muscles near joints.
- Tendinitis: Inflammation or irritation of a tendon, the thick cord that attaches muscle to bone.
- Rotator cuff tears: A tear in the group of muscles and tendons that surround the shoulder joint, causing pain and limited movement.
Preventing SIRVA
Proper vaccine administration is crucial to avoid SIRVA. Here are key steps that healthcare professionals use:
- Proper Training: Healthcare providers receive thorough training on correct injection techniques.
- Precise Location: The injection should target the deltoid muscle, avoiding the shoulder joint area. This usually means the injection should be two finger-widths below the bony point on the outer edge of your shoulder.
- Needle Length: Using the appropriate needle length for each patient also contributes to preventing SIRVA.
How To Address SIRVA
If you suspect you have SIRVA, here are steps to take:
- Consult a healthcare professional: Get an accurate diagnosis.
- Rest: Avoid activities that worsen your symptoms.
- Pain Relief: Over-the-counter pain relievers may help reduce pain and inflammation.
- Physical Therapy: A physical therapist can provide exercises to improve the range of movement.
- Steroid Injections: In some severe cases, corticosteroid injections may be used to reduce the inflammation.
| Aspect | Description |
|---|---|
| What | Rare complication from improperly administered vaccine too high on the shoulder |
| Why | Injection given too close to/in shoulder joint, not the deltoid muscle. |
| Symptoms | Shoulder pain, reduced arm movement. |
