New Covid boosters look a lot like the old ones. Doctors worry that could lead to errors.

Experts are concerned that the updated Covid boosters look too similar to previous versions of the vaccine, and people could receive the wrong dose in error.

As updated Covid booster shots roll out across the nation, many experts are raising an eyebrow — and perhaps squinting at the label. That's because the new doses come in capped vials that look strikingly similar to the old ones.

It's a design decision, experts say, that could result in some people mistakenly receiving the wrong dose.

Pfizer-BioNTech’s updated booster for people 12 and up comes in vials that have a gray cap with gray labeling — the same color scheme as its original vaccine, which is still being used for people's primary vaccinations.

Moderna’s updated booster for adults comes in vials that have a dark blue cap with gray labeling; its vaccine vials for children 6 through 11 — which contains the drugmaker's original formulation — have the same dark blue cap. (The vaccine used for primary vaccinations for adults has a red cap.)
