Young children are considered to be at “high risk” from flu, with an increased risk of developing more serious symptoms and complications. This is why having a flu jab to vaccinate against this potentially deadly virus is so important. Even without severe symptoms, small children are also highly efficient at spreading infection to others.
Children who have not been vaccinated previously are recommended to receive a second, booster 4 weeks after the initial flu vaccination. The booster dose is needed for young children to produce a more completely protective immune response.
Following this, they will only need a single annual dose in future.
If your child needs two flu vaccines in one season, try to get them vaccinated as early as possible in the season, before the flu becomes widespread in your community.
