Do You Need To Get Your Second COVID-19 Vaccine In The Same Arm?

As more and more people receive their vaccines many of the public's questions are answered. From the effect of the vaccine on mask requirements to what possible symptoms to expect, there is a lot of information out there from the CDC and other credible sources. But there is one concern that many still have: Do you need to get your second COVID-19 vaccine in the same arm?

Some people, particularly those who plan to go to drive-up vaccine locations, wonder if they'll be able to switch arms — from dominant to non-dominant arm or vice versa — for their second vaccine dose. WFMY News 2, a news station out of South Carolina, investigated whether or not you'll have to use the same arm each time you go to a drive-up vaccine location. After consulting the professionals, they revealed their findings. Their views are also supported by other experts (via Bustle). And spoiler: It's good news.

It's completely up to you

Dr. Cyntia Snider, an infectious disease and internal medicine specialist, told WFMY News 2 that it doesn't matter which arm your vaccine doses go into, as long as you get both of them. This answer was echoed by Dr. Sanjeev Jain, a double board-certified doctor of immunology and internal medicine at Columbia Asthma and Allergy Clinic. When interviewed by Bustle he was just as clear as Dr. Snider. "There is no risk or benefit to receiving your second injection in the same or opposite arm," he revealed.

Although the CDC doesn't offer specific guidance on arm selection, they do recommend seeking your doctor's advice if you develop a rash. If you happen to get a rash, inform your medical provider at the time of your next injection. In these cases, your doctor may feel it is best for you to switch arms for your second dose.

Ultimately, though, it is up to you. The vaccine can leave your arms sore and muscles stiff for a couple of days and that may affect your choice. But as long as you get both doses, your arm selection is purely a matter of personal preference.
