Approval of Novavax covid vaccine by Europe - Meanwhile Europe's medicines watchdog has approved the covid vaccine by US-based Novavax, which uses a more conventional technology which the biotech firm hopes will reduce vaccine hesitancy. In a statement released on Monday, the European Medicines Agency said: "EMA has recommended granting a conditional marketing authorisation for Novavax's Covid-19 vaccine Nuvaxovid to prevent covid in people from 18 years of age." Novavax is the fifth vaccine to be recommended for authorisation in the European Union.
