Latar belakang: Hingga saat ini, pneumonia merupakan salah satu penyebab utama kematian balita di dunia. Banyak faktor yang bisa berpengaruh terhadap peningkatan kejadian pneumonia pada balita, baik aspek individu dari anak itu sendiri, perilaku orang tua, dan lingkungan. Salah satu cara yang dapat digunakan untuk mencegah terjadinya pneumonia adalah vaksinasi Pneumococcal Conjugate Vaccine atau PCVTujuan: Mengetahui hubungan antara faktor pengetahuan, sosiodemografi, sikap, dan perilaku orangtua mengenai pneumonia, serta sikap orangtua terhadap vaksinasi dengan penerimaan orangtua terhadap Pneumococcal Conjugate Vaccine pada anak usia di bawah 5 tahun di IndonesiaMetode: Penelitian dilakukan di poliklinik departemen anak Rumah Sakit Cipto Mangunkusumo, dan TPA Makara UI pada November 2020. pengambilan sampel dilakukan secara consecutive sampling. Perhitungan jumlah sampel menggunakan rumus sampel tunggal. Kriteria inklusi adalah orangtua yang memiliki anak berusia di bawah 5 tahun serta mengisi kuesioner dengan lengkap. Data dianalisis berdasarkan usia, pendidikan, pekerjaan, penghasilan, pengetahuan, sikap, dan perilaku terhadap pneumonia, serta sikap terhadap vaksinasi. Uji yang digunakan adalah metode uji Chi-square untuk mengetahui hubungan dari faktor tersebut dengan penerimaan terhadap vaksinasi pneumonia.Hasil: Sebanyak 97 (84,1%) dari 107 responden dalam penelitian ini menerima pemberian pneumococcal conjugate vaccine.Sikap orangtua terhadap vaksinasi memiliki hubungan yang signifikan dengan penerimaan orangtua terhadap vaksinasi pneumonia (p=0,000). sementara untuk usia orangtua (p=0,172), pendidikan orangtua (1,000), pekerjaan orangtua (p=0,119), penghasilan orangtua (p=0,617), serta pengetahuan (p=0,253), sikap (p=0,597) dan perilaku (p=1,000) terhadap penyakit pneumonia tidak memiliki hubungan yang signifikan dengan penerimaan orangtua terhadap vaksinasi pneumoniaSimpulan: Sikap orangtua terhadap vaksinasi dapat mempengaruhi penerimaan orang tua terhadap vaksinasi pneumonia
