Cervical cancer vaccine can be repeated

It is not recommended to fight like this. First of all, it is a waste, and then it is really a bivalent vaccine. If there is a quadrivalent vaccine, it has 70% of cervical cancer that can be prevented. Therefore, it is a waste from an economic point of view to fight a nine-valent vaccine. However, if you want to fight, there is nothing special. It can be fought and there is nothing. Because it is a protein vaccine, and then there is not much impact, but it is not recommended to use it.
