Is it okay to skip DPT vaccine?

Hi mommies! My daughter is 3 months old and she's scheduled to have her 3rd DPT vaccine tomorrow sa health center namin. We're still yet to confirm if may immunization tomorrow but even so, I don't think I want to take my baby out because of virus nga. Is it okay lang kaya to have it next month or as soon as bumalik na sa dati lahat? Thanks in advance.
