Translation of "Antivenom" in Japanese

Finally taken to hospital and given the correct antivenom,

そこで病院へ行き 血清を打たれ―

How poorly distributed the antivenoms are, and how patchy the antivenom efficacy is.

抗毒血清の数が足りず 効くか分からないのも困る

[narrator] And don’t think just because you have antivenom you’re out of the woods.

血清があっても すぐ安心はできません
