Substandard and falsified vaccines put individuals at risk of contracting preventable diseases and erode public trust in vaccines and the healthcare system. Vaccine manufacturers, regulators and law enforcement need quality control tools that help keep these dangerous and sometimes deadly products off the market. USP recognizes this need and provides resources that support the high-quality manufacturing, packaging, and release processes of vaccines. These resources help to address broader challenges associated with vaccine distribution and administration, which further contribute to public confidence in vaccination efforts.
