Why Children Need Vaccinations Beyond Their First Birthday
Babies receive many vaccines during their first year.
Their vaccines should not stop after their first birthday.
Some vaccines need extra doses to keep protection strong.
Children may also meet more people in their second year at playgroups, day-care centres and public places.
This can give infections more chances to spread.
Vaccines can help prevent illnesses such as measles, chickenpox, hepatitis A and flu.
Parents should check their child’s vaccination record regularly.
A paediatrician can explain which doses are due or missed.
Vaccinations should continue during a child’s second year to prevent gaps in protection.
Growing contact with playgroups, day-care centres and public spaces can increase infection exposure.
Hepatitis A vaccination generally begins at 12 months, followed by a second dose at 18 to 19 months.
MMR, chickenpox and other booster doses are recommended at different points during the second year.
Keeping vaccination records current helps parents identify upcoming, missed or catch-up doses.
