(CNN) — Just as the Biden administration is moving up its deadline to make vaccine eligibility available to all adults by April 19, the supply of at least one of the vaccines, Johnson & Johnson’s, is slowing down, and with some of its manufacturing challenges at an independent plant that has had problems in the past, it’s unclear exactly when it will pick back up again.

Next week, the number of Johnson & Johnson Covid-19 vaccines allocated to states and other jurisdictions by the federal government is expected to drop 84%, according to a CNN analysis of data from the US Centers for Disease Control and Prevention. In contrast, the supply of Pfizer/BioNTech and Moderna vaccines remain steady for next week.
