A review of fetal cell lines used during drug development: Focus on COVID-19 vaccines, transplant medications, and biologics.

Purpose: The recent coronavirus disease 2019 (COVID-19) pandemic and vaccine mandates have increased the number of patient questions related to how fetal cell lines are used during drug development and final manufacturing. This article describes our literature search and review of COVID-19 vaccines, transplant medications, and biologics whose development included use of fetal cell lines.

Summary: A detailed literature search was conducted to identify the common fetal cell lines used in COVID-19 vaccine development; the two most prevalent fetal cell lines identified were HEK-293 and PER.

A mucoadhesive biodissolvable thin film for localized and rapid delivery of lidocaine for the treatment of vestibulodynia.

Vestibulodynia (VBD), an idiopathic pain disorder characterized by erythema and pain of the vulvar vestibule (the inner aspect of the labia minora and vaginal opening), is the most common cause of sexual pain for women of reproductive age. Women also feel discomfort with contact with clothing and tampon use. As most women with this disorder only have pain with provocation of the tissue, topical anesthetics applied to the vestibule are the current first line treatment for temporary pain relief.
