Is the vaccine Havrix Is Junior actually unavailable in pharmacies?

Good morning. Recently, I wanted to vaccinate my child with Havrix Junior (another dose). Unfortunately, after the medical qualification, the nurse informed me that they did not have the vaccine in stock. Apparently, it's hard with availability and deliveries from the manufacturer right now. Please let me know if this is really the case? Can I get this vaccination done at a different clinic than the one where my child is enrolled?
Thank you in advance for your reply. Best regards
