Officials hope the vaccine, made from a more conventional technology than the others, will help persuade those hesitant about vaccination to come forward.
"At a time where the Omicron variant is rapidly spreading, and where we need to step up vaccination and the administration of boosters, I am particularly pleased with today's authorisation of the Novavax vaccine," said EU chief Ursula von der Leyen.
The Novavax vaccine now sits alongside the EU's other authorised COVID-19 jabs, from BioNTech/Pfizer, Moderna, AstraZeneca and Johnson & Johnson.
Called Nuvaxovid, the Novavax offering is a vaccine based on so-called protein subunit technology, which is tried and tested, having been used for decades to vaccinate people against diseases including hepatitis B and whooping cough.

Unlike mRNA vaccines produced by BioNTech/Pfizer and Moderna, Nuvaxovid does not need to be stored in ultra-low temperatures, giving it a logistical advantage in difficult-to-access regions.
Earlier on Monday, the European Medicines Agency (EMA) gave the green light for the jab to be given conditional marketing authorisation.
Careful study of clinical data from studies in Britain and in the United States and Mexico had showed it to be "robust," meeting EU criteria for "efficacy, safety and quality," it said.
Von der Leyen, in her statement, said she hoped the newest addition to the EU's range of vaccines would "offer a strong encouragement to everyone who has not yet been vaccinated or boosted, that now is the time to do so."
EU health commissioner Stella Kyriakides said that Nuvaxovid "shows promising results against COVID-19." Vaccinations and boosters were "today more important than ever if we are to stem the wave of infections and counter the emergence and spread of new variants", she said.
Novavax, a US biotech firm based in the state of Maryland, has already won emergency-use approval for its vaccine in Indonesia and the Philippines, and Japan has agreed to buy 150 million doses.
It would also make an application to the US regulator, the Food and Drug Administration, said the company, whose production and vaccine-vetting process has been plagued by delays.
Novavax said it has also filed for approval in Britain, India, Australia, New Zealand, Canada, and with the World Health Organisation (WHO).
The new US study will include up to 1,420 volunteers ages 18 to 55 to test the updated Omicron-based shots for use as a booster or for primary vaccinations. Researchers will examine the tweaked vaccine’s safety and how it revs up the immune system...
Member states are struggling to contain a third wave of the epidemic and kick-start vaccine programmes slowed by a shortfall in deliveries, and Britain has warned the bloc against resorting "vaccine nationalism."
The fresh suspensions were a major blow to a global immunisation campaign that experts hope will help end a year-long pandemic that has already killed over 2.6 million people and decimated the global economy.
The announcement comes as the Ministry of Health and Prevention on Sunday expanded coronavirus vaccine eligibility in line with the UAE's proactive policy to ensure the health and safety of all community members.
