37 DCVMN members each supplied from 50k to 1.5B doses in 2018/2019 (according to a survey), totaling at approximately 3.5 billion doses in this timeframe. There is potential to increase the manufacturing capacity to accommodate a higher demand if these members go beyond typical parameters such as the filling capacity of single-dose syringes and routine Monday-Friday operations. Additionally, the approximations of doses did not include unreleased or bulk in-stock doses, and 4 members were not counted in the survey. Some vaccines included in the count were monovalent.
