The Hpv vaccine, also known as the cervical cancer vaccine, is a vaccine that helps women prevent cervical cancer. The reason why women with a history of sexual intercourse need to go for the necessary gynecological examination first is that if the patient’s cervix is already infected with HPV, going for the vaccine directly without an examination without knowing about it can easily aggravate the patient’s condition and make the vaccine ineffective. Also, you must be careful when getting the vaccine and try to avoid your menstrual period. The HPV vaccine is not recommended for patients who are allergic to yeast and proteins, and it is also not recommended for women who are pregnant or breastfeeding.
