Young kids are considered at “high risk” from the flu which means they have an increased risk of developing more serious symptoms and complications, which can be fatal. This is why having a flu jab to vaccinate against this potentially deadly virus is so important.
Children who have not been vaccinated previously are recommended to receive a booster 4 weeks after the initial flu vaccination. The booster dose is needed for young children to produce a protective immune response, meaning the second dose helps the body develop enough antibodies for good protection.
Going forward, they will only need a single annual dose.
If your child needs two flu vaccines in one season, try to get them vaccinated as early as possible. This is so that your child can be double-vaccinated before the flu is widespread in your community.
