Vaccines under study: non-HIV vaccines

Area of Science:

• Immunology
• Vaccinology
• Dermatology

Background:

• Vaccines represent a major public health success, saving numerous lives.
• Recent advances include vaccines for human papillomavirus and herpes zoster, improving dermatologic therapy.
• However, many infectious diseases lack preventive vaccines, particularly those affecting skin and mucous membranes.

Purpose of the Study:

• To review potential vaccines against infectious agents causing cutaneous and mucocutaneous manifestations.
• To focus on vaccine candidates that have not yet received licensure.
• To discuss the challenges and stages in vaccine development.

Main Methods:

• Literature review of preclinical and clinical studies on vaccine candidates.
• Identification of infectious agents with significant dermatologic and mucocutaneous impact.
• Analysis of the development pathway for unapproved vaccines.

Main Results:

• Several vaccine candidates targeting viruses, bacteria, fungi, and protozoa are under development.
• The path to vaccine licensure involves extensive and often challenging preclinical and clinical testing.
• Many potential vaccines do not successfully complete the approval process.

Conclusions:

• Despite progress, a significant need exists for new vaccines against skin-related infectious diseases.
• The development pipeline includes diverse candidates, but regulatory approval remains a hurdle.
• Continued research and development are essential to bring new preventive vaccines to fruition.
