Can the HPV vaccine be administered during menstruation?

Preventing disease is a concern for everyone. When vaccination is required, individuals typically visit a hospital promptly to receive the injection. For men, this process usually presents few difficulties; however, women may face challenges related to their menstrual cycle. During this time, many women worry about potential adverse reactions to vaccination—so, can the HPV vaccine be administered during menstruation?

Can the HPV vaccine be administered during menstruation?

The HPV vaccine can technically be administered during menstruation, but it is generally advisable to avoid vaccination during this period. Women’s immune resistance tends to be lower during menstruation; therefore, it is preferable to schedule vaccination after menstrual bleeding has completely ceased. It is important to note that medication use should be minimized during menstruation—especially drugs that may stimulate uterine contractions or promote blood circulation and resolve blood stasis. For example, herbal preparations such as *Shujin Huoxue Pian* (a traditional medicine used to relax tendons and invigorate blood circulation) may increase menstrual flow or prolong the duration of menstruation. Thus, drug use should be kept to a minimum during this time. Dietary considerations are also important: avoid highly stimulating foods, as they may affect both menstrual volume and duration.

Menstruation typically does not interfere with vaccination, so administering the HPV vaccine during this period is permissible. Although some people believe vaccination during menstruation may lead to menstrual discomfort, reduced immunity, or increased side effects, in reality, the HPV vaccine rarely causes significantly heightened adverse reactions following administration during menstruation. Moreover, receiving the HPV vaccine during menstruation generally does not compromise its efficacy. Currently, the standard HPV vaccination schedule involves three doses: the first dose is followed by the second dose two months later and the third dose six months after the first. If menstruation coincides with a scheduled vaccination appointment—and especially if the individual feels unwell—it is reasonable to postpone the dose until after menstruation concludes and then resume the vaccination schedule accordingly.

During menstruation, attention should be paid to personal hygiene, daily dietary habits, and the correction of unhealthy lifestyle practices. We hope this information proves helpful to you.
