the cause of jock itch (tinea cruris) is a fungus not a virus. it has nothing to do with the pneumococcal vaccine. the fact that you got tinea cruris again just a coincidence.
can the pneumococcal 13 vaccine pcv13 cause jock itch? . i recently got the pneumococcal pcv13 vaccination. the next day i had tinea cruris. i have a history of this and i am convinced that the cause was antibiotics. i had not had the condition for many months but the day after receiving the shot it flared up again. i understand that tinea cruris is a virus and that the pneumococcal pcv13 injection is bacterial but i cannot make any other connection with this flare up. . i see that one possible side effect is urticaria which i have also had.
