Vaccination to prevent otitis media due to Streptococcus pneumoniae

Otitis media due to *Streptococcus pneumoniae* is an acute bacterial infection and inflammation of the middle ear space, most frequently affecting infants and young children Vaccination aims to induce serotype-specific mucosal and systemic neutralizing antibodies to inhibit pneumococcal nasopharyngeal colonization and local invasion, thereby preventing acute middle ear infection and complications such as tympanic perforation, mastoiditis, and conductive hearing loss

Otitis media due to *Streptococcus pneumoniae* is an acute bacterial infection and inflammation of the middle ear space, most frequently affecting infants and young children Clinical manifestations include acute otalgia, fever, irritability, middle ear effusion, and marked tympanic membrane erythema or bulging Vaccination aims to induce serotype-specific mucosal and systemic neutralizing antibodies to inhibit pneumococcal nasopharyngeal colonization and local invasion, thereby preventing acute m...

Pathophysiologically, the condition often develops following viral upper respiratory tract infections that impair Eustachian tube function, facilitating the ascent, colonization, and proliferation of encapsulated pneumococcal bacteria in the normally sterile tympanic cavity
