Dear Editor,
W e read with interest the publication by Deng Z et al. on “Post-SARS-CoV-2-vaccine shoulder pain: Is it relevant to the vaccine injection? – Correspondence” [1]. The authors noted that the “Vaccine injection strategy had no effect on pain, but the type of vaccine played an affecting role. The findings of this study not only supported safety of SARS-CoV-2 vaccine … this adverse event [1].” We agree that there are several possible causes of shoulder pain in a vaccine recipient. Deng Z et al. mentioned the effect by the type of vaccine. Indeed, pain perception is different in different individuals. The type of vaccine might or might not be the main cause of pain. The technique of administration is a factor that should be considered. Most reported incidences of pain after vaccination are due to poor administration techniques and the background physiological status of the vaccine recipient for whom obesity can be an important contribution risk factor [2]. Furthermore, post vaccination activity can also be a factor associated with pain. The present study by Deng Z et al. gives many interesting observations but further studies are required to reach a definitive conclusion.
