Vaccines Against Pneumonia: Current Updates.

Pneumonia is one of the global leading causes of mortality and impacts all age groups. Both viruses and bacteria can contribute to the development of lower respiratory tract infections and incidences of each vary in different age groups and immune statuses. Vaccines exist to target many of the pathogens associated with pneumonia including influenza, COVID-19, respiratory syncytial virus, pneumococcal pneumonia, pertussis, and Haemophilus influenzae type b. Vaccinations have demonstrated positive effects at reducing rates of infection and hospitalizations related to pneumonia. However, vaccination rates remain low and barriers including vaccine hesitancy exist among the general population.
