The recommendation to ensure that the 10-month-old receives the pneumococcal vaccine series is effective in decreasing ear infections, particularly otitis media, because this vaccine provides protection against Streptococcus pneumoniae, a common bacterial pathogen involved in many cases of this condition.

Pneumococcal vaccines, such as PCV13, significantly reduce the incidence of infections caused by certain strains of bacteria that frequently lead to respiratory infections, including those that can cause ear infections. Vaccination not only helps prevent the development of these infections but also contributes to herd immunity, thereby indirectly protecting children who may be at higher risk.

The other options address common practices or concerns regarding ear infections but do not have a direct impact on preventing them. Feeding a baby in a horizontal position can increase the risk of fluid entering the eustachian tube, which can lead to more ear infections. Eliminating the use of a pacifier can have varying effects; while some studies suggest a link to reduced ear infections, the effect is not as strong as vaccination. Rinsing the mouth after feedings may help with oral hygiene but does not prevent ear infections. Thus, vaccination remains the most effective strategy in reducing the incidence of otitis media in young children.
