If my child has received Fluenz Tetra as their first flu vaccine, can I use Vaxigrip Tetra as the second dose?

If a child (3.5) has taken FluenzTetra as the first flu vaccine, can VaxigripTetra be used as the second dose? (FluenzTetra is no longer in pharmacies.) Is it better to wait until autumn and then carry out two vaccinations with one vaccine? (the first flu vaccination in a child should consist of two doses with an interval of at least 4 weeks, and subsequent doses may be from singles)
