Left arm or right? Why it matters where you get your vaccine [View all]

If you’re rolling up your sleeves for a flu or COVID vaccine this season, you may not give much thought to which arm ultimately receives the jab.

But new Australian research suggests location does matter when it comes to generating a strong immune response from booster vaccines.

The study, published in the journal Cell on Tuesday, found booster vaccines given in the same arm as the first dose generated a stronger and more rapid immune response.

The findings, made in mice and replicated in humans, shed light on a previously understudied corner of the immune system, and could eventually be used to develop next-generation vaccines that require fewer boosters.
