Here in Finland, 8- or 9-graders make a one- or two-week "Introduction to working life" internship at a workplace of their choice (TET, työelämään tutustumisjakso).
UPDATE (August 6th, 2021): I am now fully vaccinated according to the CDC's definition! I got the first Biotech/Pfizer shot on May 15, 2021, so my shot spacing was 10 weeks.
