Injections can cause muscle damage in the arm if administered incorrectly. This injury is known as Shoulder Injury Related to Vaccine Administration, or SIRVA. SIRVA occurs when a vaccine is injected too high or too deep into the shoulder, damaging the muscles or tendons in the rotator cuff or the bursa. This can lead to inflammation and pain, and in some cases, long-term disability. SIRVA is typically associated with vaccines administered in the upper arm, such as the flu or COVID-19 vaccine, but it can occur with any injection given in the shoulder region. To prevent SIRVA, medical workers are trained to identify specific physical landmarks on the arm to guide them to the correct injection site.

What You'll Learn
Injection angle and depth
The needle length is determined by the patient's weight, age, and amount of adipose tissue at the injection site. It should be long enough to reach the muscle but not so long that it can cause further damage. The needle should be inserted with a quick, steady, and smooth motion to reduce discomfort.
To locate the correct injection site in the deltoid muscle, the patient's upper arm and shoulder are exposed, and the patient relaxes their arm at their side. The nurse then palpates the lower edge of the acromion process, forming the base of a triangle with the midpoint of the lateral aspect of the upper arm. The injection site is found in the centre of this triangle, approximately 2.5cm below the acromion process.
Incorrect injection methods, such as injecting too high or too deep, can cause shoulder injuries, known as SIRVA (shoulder injury related to vaccine administration). SIRVA can result in muscle damage, inflammation, and pain, with potential long-term effects on arm mobility and functionality.

Needle length
SIRVA injuries are commonly associated with vaccines administered in the upper arm, such as the flu or COVID-19 vaccine. However, they can occur with any injection given in the shoulder region. The injury usually occurs when the needle is inserted too high, puncturing the bursa, which are fluid-filled sacs that protect the tendons in the shoulder. This can lead to inflammation of the bursa, tendons, and ligaments, causing significant pain and discomfort.
To prevent SIRVA, it is important that the administrator of the vaccine inserts the needle into the thickest portion of the deltoid muscle, which is the main shoulder muscle. The needle should be inserted at a 90-degree angle, approximately 2.5 cm below the acromion process, which is the bony prominence at the top of the shoulder joint. This ensures that the needle does not hit the bone or penetrate the bursa.
In some cases, SIRVA can result from the use of a needle that is too long for the patient. If the needle is too long, it may increase the risk of the needle hitting the bone or puncturing the bursa, even if the injection site is correct. Therefore, it is important for healthcare providers to consider the patient's anatomy and choose an appropriate needle length to avoid causing muscle damage or other injuries.
Overall, needle length and placement play crucial roles in preventing muscle damage in the arm during injections. By ensuring proper needle length and placement in the thickest portion of the deltoid muscle, the risk of SIRVA and other complications can be significantly reduced.

Incorrect injection methods
To avoid SIRVA, it is crucial that vaccinations are administered into the middle of the deltoid muscle at a 90-degree angle. If the vaccine is injected too high or too deep, it can damage the muscles, tendons, or bursa in the shoulder, leading to inflammation and injury.
Incorrect injection techniques can also result in nerve damage, muscle damage, blood vessel injury, and injection site reactions such as redness, swelling, and increased pain. In some cases, incorrect injections can lead to medication leakage, reducing the effectiveness of the treatment.
Intramuscular injections, in particular, require accurate administration to avoid complications. Selecting the correct injection site is essential, taking into account factors such as patient anatomy, age, and the type and volume of medication. Improper site selection and inadequate technique are common causes of incorrect intramuscular injections.
In low and middle-income countries, incorrect intramuscular injections are prevalent due to improper training and a lack of understanding of anatomy. Injuries causing injection nerve palsy are often preventable through proper training and safer injection techniques.

Rotator cuff injuries
The symptoms of SIRVA include sharp, localized pain in the shoulder, which may radiate down the arm or increase in intensity over time. This pain can significantly affect an individual's ability to perform daily activities and sleep. SIRVA injuries usually manifest as sudden deltoid pain or a decreased range of motion within 48 hours of vaccination.
Treatment options for rotator cuff injuries, including SIRVA, vary depending on the severity and can range from rest to surgery. Initial treatments may include rest, physical therapy, pain medication, and steroid injections. In more severe cases, corticosteroid injections may be used to reduce inflammation and provide temporary pain relief. Surgery is considered a last resort and is typically only an option if conservative treatments have failed or if the tear is large or from a recent injury.
It is important to note that rotator cuff injuries can also occur due to wear and tear, repetitive overhead activities, and acute injuries such as falling on an outstretched arm or lifting heavy objects. Athletes, especially in tennis, swimming, and baseball, and individuals in certain occupations, such as carpenters, construction workers, and painters, are at a higher risk of developing rotator cuff injuries due to repetitive overhead movements or heavy lifting.

Treatment options
Nerve Modulating Medication
Nonsteroidal anti-inflammatories, as well as nerve modulating agents such as gabapentin and pregabalin, can be used to treat nerve injuries.
Physical Therapy
Therapy can focus on joint mobilization, deltoid and rotator cuff muscle strengthening, and nerve gliding and desensitization.
Surgery
In more severe cases, surgery may be required to repair damaged tissue. This is often the case with rotator cuff injuries, which can be caused by improper injection.
Rest
In some cases, rest may be recommended, especially with tendonitis.
Exercise
Exercises can help with certain injuries, such as a frozen shoulder.
Steroid Injections
Steroid injections can be used to treat frozen shoulder injuries.
Ice Packs
Applying a cool compress or ice pack to the injection site can help reduce pain and inflammation.
Correct Injection Technique
Physicians can prevent muscle damage by adopting proper landmarking and injection techniques. This includes choosing the correct needle length and insertion angle.

Frequently asked questions
SIRVA stands for Shoulder Injury Related to Vaccine Administration. It is a rare but serious complication that occurs when a vaccine is administered too high in the deltoid or into the shoulder joint.
SIRVA is caused by incorrect injection methods, such as incorrect needle placement or the use of a needle that is too long. This can result in the needle hitting bone or puncturing the bursa, a fluid-filled sac that protects the tendons in the shoulder.
Symptoms of SIRVA include sudden onset shoulder pain, decreased range of motion, and arm weakness. These symptoms typically manifest within a few days or weeks of vaccination and can last for months or even years.
Treatment for SIRVA may include rest, physical therapy, pain medication, steroid injections, or, in rare cases, surgery to repair damage to the shoulder muscles and tendons.
Yes, you may be eligible for compensation if you have suffered a SIRVA injury due to negligent vaccine administration. You can seek legal advice to understand your options and determine whether you have a valid claim.
