Infant or child aged 6 months to 4 years

For those who are already primed or have been infected, a single dose is sufficient from 6 months after the last infection or injection.

For the others, a primary vaccination schedule should be carried out with 2 doses administered 21 days apart, followed by a 3rd dose administered 8 weeks after the 2th dose.

To find out if you are affected by the annual dose and where to do it, you can consult the ministry of health page dedicated to this issue.
