The Finnish Institute for Health and Welfare (THL) on Tuesday reported that some 50,000 of Finland's roughly 250,000 youngsters in the 12-15 year-old age group had received one shot of a coronavirus vaccine.
The THL has outlined that young teens can decide whether or not to get the jab.
Teens talking to Yle said their friends' opinions weighed the most in their decision to get vaccinated against coronavirus.
Fifteen-year-old Anttoni Lindgren from Vantaa told Yle he wasn't sure about getting the coronavirus vaccine.
"If someone I know gets it, then I'll get it too. I believe it's safe," he said.
In Vantaa and Espoo some 60 percent of 12-15 year-olds have received their first vaccine dose. In Helsinki around half of kids in the age group have had the injection.
City officials told Yle that vaccinating teens in schools has been effective. In Vantaa two-thirds of youngsters have received their shot in school, according to Piia Niemi-Mustonen of Vantaa's preventive health care services.
"Vaccinations are progressing well in this age group. We met our goal of making vaccines available in the first week of school," she explained.
Niemi-Mustonen also said young people do not seem to be influenced by online coronavirus vaccine disinformation campaigns — a sentiment echoed by vice principal Petra Sundell at Vantaa's Jokiniemi school.
Sundell said schools have been focusing on media literacy skills, though there hasn't been a special focus on vaccine disinformation.
On Friday police detained three protesters at a school in Helsinki after they tried to disrupt the vaccination of 12-15 year-olds.
