Introduction
The quadrivalent vaccine generally refers to the quadrivalent HPV vaccine. People over 45 years old can usually receive the quadrivalent HPV vaccine. This vaccine primarily prevents cervical cancer caused by four types of HPV and is typically recommended for individuals aged between 20 and 40. By age 45, most people have passed their peak sexually active period, and their immune function tends to decline, which may result in lower antibody production after vaccination and reduced protective efficacy.
The quadrivalent vaccine generally refers to the quadrivalent HPV vaccine. People over 45 years old can usually receive the quadrivalent HPV vaccine, although its effectiveness may be reduced. The specific analysis is as follows:
The quadrivalent HPV vaccine is primarily designed to prevent cervical cancer caused by four types of HPV: HPV16, HPV18, HPV6, and HPV11. It is typically recommended for females aged 9 to 45, with three doses administered at months 0, 2, and 6 to enhance protection against the virus. However, individuals aged 45 and above are generally past their sexually active years and may have weaker immune systems, which could result in lower antibody production after vaccination and thus reduced preventive efficacy.
Therefore, it is recommended that women, if possible, receive the quadrivalent HPV vaccine within the recommended age range.
