Monitoring ambient temperatures experienced during delivery of human papillomavirus vaccine in Uganda.

As part of project Optimize a five-year human papillomavirus (HPV) vaccine demonstration project is under way in Uganda and three other countries to demonstrate how existing health systems can be adapted to successfully provide HPV vaccine to young adolescent girls. HPV vaccine is a strong candidate for storage and transport in a controlled temperature chain at temperatures higher than the standard 2o to 8oC cold chain storage.
