Anti-vaccine protesters clashed with police in Munich on Wednesday, after the country’s top ethics council narrowly approved a COVID-19 vaccine mandate for adults over age 18. The demonstration comes as Europe deals with a surge in COVID-19 cases driven by the Omicron variant. Police estimate approximately 5,000 people showed up at the protest. Eleven people were arrested, they said. Health officials expect Omicron will be the dominant variant in the country by mid-January.
