Pfizer says a booster dose of its COVID-19 vaccine appears to offer important protection against the new omicron variant.

Pfizer and its partner BioNTech tested how well vaccine-produced antibodies could neutralize omicron in lab dishes. They found significant weakening after the standard two doses. But a booster dose increased antibody levels by 25-fold.

The companies said two doses still may protect against severe illness, but they are working to develop an omicron-specific vaccine in case it’s needed. They announced the findings Wednesday in a press release. The data is preliminary and hasn’t undergone scientific review.
