Which technique is recommended to prevent SIRVA during vaccine administration?

The recommended technique to prevent Shoulder Injury Related to Vaccine Administration (SIRVA) involves targeting the lower portion of the deltoid muscle for the injection. This practice is crucial because injecting into the correct anatomical location minimizes the risk of inadvertently introducing vaccine into the shoulder capsule or surrounding structures, which can lead to pain and complications associated with SIRVA.

By properly locating the lower part of the deltoid muscle, vaccine administrators can ensure that the injection is given in the appropriate muscle mass, enhancing absorption and reducing discomfort. It protects critical areas like nerves and tendons that may otherwise be affected if the injection is given too high in the shoulder.

The other techniques mentioned, such as administering the vaccine while standing or using a larger needle, do not specifically address the anatomical considerations necessary for preventing SIRVA. Injecting into the shoulder capsule is counterproductive, as it increases the risk of injury rather than preventing it. Therefore, proper targeting of the deltoid muscle during vaccine administration is key to preventing complications associated with SIRVA.
