Necrotizing Fasciitis after Influenza Vaccination: Case Report - Abstract
Background: Necrotizing fasciitis is a soft tissue infection, mainly related to penetrating trauma, which creates a gateway for pathogens.
Case presentation: A female patient, 8 months old, is admitted to the Pediatrics Emergency Unit of the with erythema, edema and hemorrhagic blister at the site of application of the Influenza vaccine 4 days post-vaccination.
Discussion: Necrotizing fasciitis is a dermatological condition with a polymicrobial etiology, due to the synergism of the necrotoxins of such pathogens. Tests show leukocytosis and significant elevation of C-reactive protein. Treatment should be performed with broad-spectrum antimicrobials initially and with subsequent adjustment for those of proven sensitivity, in addition to early surgical debridement.
Conclusion: Necrotizing fasciitis is a severe infection, with fast evolution which can lead to death. Its presentation after vaccination must be considered and avoided with proper hygiene and prophylactic methods during the administration of the vaccine.
