It is not recommended to take a shower within 2-3 days after the nine-valent vaccination. This is because after the nine-valent cervical cancer vaccine is administered, there will be slight pain at the injection site and some women may even experience redness. If you take a bath too early, it may cause a local lump and may cause infection. If the water is too cold or too hot, the dizziness and headache may be accelerated and the fever may persist. It is not recommended to take a bath immediately after the nine-valent vaccination, but at least to observe for a period of time, and it is okay to take a bath after 3 days if there are no adverse reactions.
