If you can’t get the quadrivalent cervical cancer vaccine, you can get the bivalent one. Cervical cancer is mainly caused by HPV16 and HPV18 subtypes, and there are three types of cervical cancer vaccines, i.e., bivalent, quadrivalent and nine-valent, of which all three are targeted at HPV16 and HPV18, so the three types of vaccines are effective in preventing cervical cancer. The quadrivalent vaccine, compared to the bivalent vaccine, protects against two more subtypes, namely HPV6 and 11. The cervical cancer vaccine is more effective the earlier you get it, if the quadrivalent vaccine is difficult to book. Both the bivalent and quadrivalent vaccines are given before the age of 45, so if you can’t wait for the quadrivalent, you can absolutely choose to get the bivalent vaccine, which can also help prevent cervical cancer.
