Moderna sues Pfizer over Covid vaccine

Moderna said Friday it is suing rival vaccine makers Pfizer and BioNTech, alleging the partners infringed on its patents in developing their Covid-19 shot that has been administered to hundreds of millions around the world.

The lawsuits filed both in US district court in Massachusetts, and in regional court in Dusseldorf, Germany, set up a showdown between the leading manufacturers of Covid-19 shots that are a key tool in the fight against the disease.
