KT Tape for Rotator Cuff and Shoulder Injuries, Risk for shoulder conditions after vaccination: A population-based study using real-world data, Don't aim too high: Avoiding shoulder injury related to vaccine administration, Subdeltoid/subacromial bursitis associated with influenza vaccination, Risk scales: benefits of vaccines far outweigh the risks, Shoulder injury related to vaccine administration and other injection site events, Shoulder injury related to vaccine administration (SIRVA) in 16 patients following COVID-19 vaccination who presented to chiropractic, orthopedic, and physiotherapy clinics in Hong Kong during 2021, Shoulder pain and injury after COVID-19 vaccination. and lower their collar, exposing only the top of the deltoid, says Marko Bodor, a California orthopedist who authored a 2006 report that described vaccination-related shoulder injuries in two of his patients.

Government immunization advisories, standard anatomy textbooks, and researchers have proposed various injection techniques and sites, but specific guidelines are lacking for the administration of IMIs in the increasingly used deltoid site. The immune cells in the muscle tissue pick up these antigens and present them to the lymph nodes. Based on ultrasound measurements, we hypothesize that vaccine injected into the subdeltoid bursa caused a periarticular inflammatory response, subacromial bursitis, bicipital tendonitis and adhesive capsulitis. An intramuscular injection site, 7.4 cm below the mid-acromion (relatively safe much below, Figure 9. Trends. COVID19 vaccines are injected into the deltoid where they are taken up by muscle cells.

But what about that other, often larger muscle, located just below our backs and above our thighs? Zone between the halfway point, Figure 7.
