Hi! So sa Novaliches, pwede mo icheck ang nearest health center ninyo, usually meron silang vaccines at mas mura talaga compared sa private clinics, honestly sobrang sulit! One of my mum friends there got her kids' vaccines sa health center tapos wala pang waiting time, kaya I'd suggest calling them muna to confirm if available na ang Hepa B at flu vaccine para hindi ka mapag-usapan, lalo na ngayon busy season ng vaccines.
