Penanganan nyeri pada bayi yang dilakukan suntikan imunisasi belum optimal, sementara metode menurunkan nyeri yang teridentifikasi tidak digunakan dengan rutin.Tujuan studi mengetahui efektivitas paket dukungan keluarga (PDK) terhadap respon perilaku nyeri bayi yang dilakukan suntikan imunisasi. Desain penelitian quasi eksperiment, sampel 30 bayi intervensi dan 30 bayi kelompok kontrol. Pengukuran nyeri menggunakan modified behavior pain scale (MBPS) melalui rekaman video. Hasilnya terdapat perbedaan rerata respon nyeri kelompok intervensi lebih rendah dibandingkan dengan kelompok kontrol dimana p value < 0,05 (p = 0,000 pada α = 0,05). Implikasi keperawatannya adalah optimalisasi keterlibatan keluarga dalam menajemen nyeri bayi yang dilakukan suntikan imunisasi.
