Final answer:
The H1N1 vaccine is recommended for children between the ages of 6 months and 19 years, with a yearly flu vaccine recommended for children who are at least 6 months of age. Children younger than 5 years old are at high risk of developing serious complications from the flu and should receive the vaccine.
Step-by-step explanation:
The H1N1 vaccine, also known as the swine flu vaccine, is recommended for children between the ages of 6 months and 19 years.
The Center for Disease Control and Prevention (CDC) recommends that children who are at least 6 months of age receive a flu vaccine each year.
This is especially important for children younger than 5 years old, as they are at high risk of developing serious complications if they get sick with the flu.
