New research from CDC, published in the December issue of Pediatrics, shows that the virus that causes mumps continues to circulate in the United States, primarily infecting people vaccinated against it, including children.

Pharmacists have all heard the phrase “children are not little adults.” It’s popular for a reason: it represents the dangers of simply scaling adult drug dosages to children. Adult physiology, however, has historically been used to scale pediatric dose recommendations.

In a new analysis, CDC said there was a large decline in essential childhood vaccinations in the early months of the pandemic last year, but rates did not return to pre-pandemic levels with the lifting of the stay-at-home orders.
