Vaccination is a vital tool to reduce the presence and severity of COVID-19 cases in the workplace, in communities, and in the nation as a whole. The spread of COVID when working in customer facilities and project sites can lead to costly site shutdowns, for which Wärtsilä could be deemed financially responsible. Many local government authorities require proof of vaccination to enter the state or country, and many of our customers require proof of vaccination to be on a project site. In line with legal regulations Wärtsilä has implemented a COVID-19 policy on vaccination and testing to reduce the risk of transmission on Wärtsilä premises. Wärtsilä strongly encourages all employees to be vaccinated to protect themselves and other employees.
