What should you do if you accidentally give Shingrix subq as opposed to IM?
Shingrix is a vaccine indicated for prevention of herpes zoster (shingles) in adults aged 50 years and older. The vaccine should be administered as a intramuscular injection (IM) in a 2 dose series.
According to the CDC:
"Shingrix should be injected intramuscularly in the deltoid region of the upper arm. However, it is not necessary to repeat vaccination if it is administered subcutaneously."
It is important to note that it is not necessary to receive Shingrix again if it was accidentally given subcutaneously instead of intramuscularly.
It has been reported that subcutaneous administration often results in more severe pain when compared to to intramuscular administration and is therefore much better tolerated when give IM.
