The source provided focuses on febrile seizures after the MMRV vaccine, not lymph node swelling.\n\nSwollen lymph nodes can be a normal response to vaccination as the immune system works, but I'd want to give you accurate information about timing and what to expect rather than guess. Your pediatrician can tell you what's typical for your toddler and whether what you're noticing needs follow-up—especially if the swelling is painful, very large, or hasn't improved over time. If you're seeing this now, it's worth a quick call to check in.","sources":"[]","thread_json":null,"topic":"vaccines","view_count":3,"created_at":"2026-08-29T23:36:52.694Z"}
