Dutch begin mass vaccinating 830,000 children, a musical variation

The Netherlands has begun vaccinating up to 830,000 children against swine flu in one of the country's largest vaccination programs.
Children between six months and four years old have received invitations to be vaccinated against the H1N1 virus.
The Netherlands has ordered enough vaccine to inoculate the entire country of 16 million people. Pregnant women, the elderly, and people with autoimmune diseases were vaccinated first.
A major center in Amsterdam is expecting 64,000 children Monday, the first day of a three-day campaign.
Children and parents arrived in a constant stream of buggies and bikes, and were greeted with clowns singing songs about how shots don't hurt - though an occasional wail could still be heard.

The NOS Jeugdjournaal (Junior News) reports (in Dutch):
