After the third vaccination, you can usually take a shower without rubbing the vaccination site. If there is any reaction such as hardness or pain at the vaccination site, it is advisable to consult the doctor at the vaccination site to clarify whether it is possible to take a shower.
Theoretically, bathing will not affect the effectiveness of the vaccine, and the eye of the vaccine is small enough that bathing will not cause infection at the injection site. Therefore, it is usually possible to take a bath after the third vaccination, but care should be taken to avoid rubbing the site of the vaccine when bathing.
If there are problems such as redness, swelling and pain at the injection site after the third vaccination, it may be necessary to wait for 24 hours before taking a shower. It is recommended to further consult the staff at the vaccination site to clarify whether it is possible to take a shower and how long the interval needs to be.
