The US pharmaceutical company Moderna has started testing a specific vaccine booster to combat the Omicron variant.
The pharmaceutical company itself makes it known with a note.
The first participant in the trial, Moderna explained, has already received the dose.
The company promises to share the results and data with health authorities to facilitate the task of identifying the best strategies for recalls against Covid 19.
600 adults underwent the trial: half already received two doses of Moderna vaccine at least six months ago, the other half also received the already authorized booster.
This specific recall against the variant will therefore be evaluated as both a third and fourth dose.
