The FDA has approved Trumenba (Pfizer), a vaccine that protects against invasive meningococcal disease caused by Neisseria meningitidis serogroup B, for use in adolescents and young adults 10-25 years old.

More antibiotics are prescribed for treatment of acute otitis media (AOM) than for any other infection in young children. Children with AOM typically present with otalgia, fever, and bulging and erythema of the tympanic membrane.

Concerns have arisen anew about possible use of biological weapons. The pathogens considered most likely to be used for this purpose are discussed in this article. A good source for additional information is www.usamriid.army.mil/education/bluebook.html.

In 2007, Merck voluntarily recalled some lots of PedvaxHIB and Comvax, two Haemophilus influenzae type b (Hib) vaccines, and temporarily stopped their production because of possible contamination, resulting in a shortage during which pediatricians were urged to defer giving Hib booster doses (normally given at 12-15 months) to healthy children. Now the FDA has granted accelerated licensure of Hiberix (GlaxoSmithKline), a monovalent vaccine conjugated with tetanus toxoid that has been used in Europe since 1996, as a booster (final) dose of the Hib series in children 15 months-4 years old....

The FDA has licensed Adacel (Aventis Pasteur) and Boostrix (GlaxoSmithKline), two new combination vaccines that include tetanus toxoid, diphtheria toxoid and acellular pertussis antigens (Tdap), for use as a booster in adolescents and adults. In the past, older children and adults were not re-immunized against pertussis because of concerns about reactions to the whole-cell vaccine previously used in younger children. The CDC Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) have recommended that either of the new Tdap vaccines replace routine...

Most respiratory tract infections are caused by viruses. Bacterial respiratory tract infections are usually treated empirically with antibiotic therapy that targets the most probable causative pathogens. Recommended antibiotic regimens for outpatient treatment of some common respiratory tract infections are listed in Table 1 for adults and Table 2 for children.

The FDA has issued an Emergency Use Authorization (EUA) for the long-acting investigational IV monoclonal antibody pemivibart (Pemgarda – Invivyd) for pre-exposure prophylaxis of COVID-19 in persons ≥12 years old (weight ≥40 kg) who have moderate to severe immune compromise and are unlikely to respond adequately to COVID-19 vaccination (see Table 1). Pemgarda is the only drug that is currently authorized in the US for pre-exposure prophylaxis of COVID-19. Tixagevimab/cilgavimab (Evusheld) was previously available under an EUA for this indication, but it lacks activity against...

Treatment of community-acquired pneumonia (CAP) is usually empiric, with selected antibiotic regimens directed against some of the most common causative pathogens. Recommended empiric regimens are listed in Table 2; recommended antibiotic dosages for treatment of CAP are listed in Tables 3 and 4. Joint guidelines for treatment of CAP by the American Thoracic Society and the Infectious Diseases Society of America (ATS/IDSA) were updated in 2019.
