Mycosis fungoides is clinically known as vulvovaginal pseudomycosis, and some adverse reactions may occur after the vaccination, but it usually does not directly cause vulvovaginal pseudomycosis. Common adverse reactions after vaccination include local itching and pain at the vaccination site, as well as fever, nausea, diarrhea, headache, fatigue, muscle and joint pain, etc. The symptoms are usually mild and do not require treatment and will resolve on their own after a few days. Pseudomonas vulvae is a common vaginal inflammatory disease caused by Pseudomonas aeruginosa, and its occurrence is not directly related to the New Crown vaccine. There are many factors that can cause pseudomonas vulvae, such as long-term use of broad-spectrum antibiotics, diabetes mellitus, heavy use of immunosuppressants, and estrogen therapy. In addition to these, fecal contamination of the vagina by Pseudomonas intestinalis infected individuals, wearing tight fitting chemical fiber underwear, and obesity that increases local temperature and humidity of the vulva are all triggers for the development of the disease. Pseudomonas vulvae is mainly endogenous. As an opportunistic pathogen, Pseudomonas can be parasitized in human vagina, oral cavity and intestine, and the three parts of Pseudomonas can be transmitted to each other, directly through sexual intercourse, and indirectly through contact with infected clothing. If you have pseudomycosis after vaccination, you should consult a doctor to clarify the real cause of the disease and follow medical advice to treat it with local medication, such as clotrimazole suppositories and mycophenolate tablets placed deep in the vagina, and oral antifungal medication such as fluconazole tablets.
