The objective of this target product profile (TPP) is to describe key attributes—minimal and optimal targets—for microarray patch (MAP) delivery of COVID-19 vaccines. MAPs, also known as microneedle patches, consist of hundreds or thousands of microscopic projections that deliver dry vaccine or drug into the skin.

The TPP describes key attributes for such a MAP for both LMIC and HIC markets. The document has been reviewed by a broad range of PATH staff with expertise in immunology, vaccine development, clinical trials, MAP technology, vaccine delivery, and vaccine manufacturing.
