Introduction
If the lump in the perineal area is due to mild inflammation without symptoms such as fever, vaccination may be considered after consulting a doctor. If the lump is merely caused by mild folliculitis or sebaceous gland blockage, with no signs of infection such as redness, swelling, heat, pain, or pus, and if the individual is otherwise in good health and the immune system is not under stress, they may inform the physician and be evaluated for vaccine eligibility. In general, this condition will not affect vaccine efficacy or worsen local symptoms.
Generally, if the lump in the perineal area is due to mild inflammation and there are no symptoms such as fever, vaccination may proceed after consulting a doctor. However, if the lump is accompanied by infection, pain, or fever, vaccination should be postponed. If in doubt, it is recommended to seek medical advice in advance. Detailed analysis is as follows:
If the lump in the perineal area is only due to mild folliculitis or blocked sebaceous glands, without signs of infection such as redness, swelling, heat, pain, fever, or pus formation, and if overall health is good with the immune system not under stress, vaccination may be considered after informing and consulting a physician. In such cases, vaccination generally does not affect vaccine efficacy or worsen local symptoms.
If the perineal lump is associated with obvious redness, swelling, pain, or pus discharge, or if systemic symptoms such as fever and fatigue occur, this may indicate an acute infection (e.g., furuncle or lymphadenitis). In such cases, the body's immune system needs to focus on fighting the infection. Vaccination could exacerbate infection symptoms and may interfere with the immune response induced by the vaccine, potentially reducing its protective effect. Therefore, treatment of the infection should come first, and vaccination should be delayed until symptoms have resolved.
After discovering a lump in the perineal area, it is important to determine its nature promptly and avoid self-medication that might delay proper treatment. Before vaccination, fully inform the doctor about the local condition so they can assess whether vaccination is appropriate. Maintain good hygiene of the perineal area in daily life and minimize local irritation.
