German-owned shipbuilder Meyer Turku said on Monday that it had completed vaccination of about 4,000 workers at its shipyard in southwest Finland.
The immunisation drive followed an apparent pneumonia outbreak in which 30 workers came down with the infection during late summer and early autumn.
The Turku University hospital said that it is no longer treating any of the patients.
The shipyard said last week that it had to order an additional 500 doses of the vaccine after supplies ran out. The vaccination campaign was conducted jointly by Meyer occupational health providers and Turku municipal health services. City health officials have said that the vaccinations will continue in the days ahead.
The National Institute for Health and Welfare, THL, is said to be still looking into the cause of the outbreak and a monitoring meeting is due to take place later this week.
