Coronavirus update: Latest Covid-19 vaccine and world news 

The number of Johnson & Johnson Covid-19 vaccine shots allocated to states and other jurisdictions by the federal government is expected to drop 84% next week, according to data from the US Centers for Disease Control and Prevention.

This week, nearly 5 million doses of the Johnson & Johnson vaccine were allocated to states and other jurisdictions, but only about 785,000 are slated for next week.

Allocations of the Pfizer/BioNTech and Moderna vaccines for next week, however, will remain steady compared to this week. About 4.7 million first doses of Pfizer and 3.5 million first doses of Moderna have been allocated for next week, along with corresponding second doses.

Allocations of the Pfizer/BioNTech and Moderna vaccines have been largely consistent week to week. However, weekly allocations of the Johnson & Johnson vaccine have varied widely. 

According to data from the CDC, the first allocation of the Johnson & Johnson vaccine – for the week of March 1 – included more than 2.8 million doses. There are no allocations of the Johnson & Johnson vaccine logged for the week of March 8, and allocations dropped to less than 500,000 doses for the two following weeks. Then, for the week of March 29, allocations jumped to nearly 2 million, before more than doubling for this week.

Here are the total allocations for the Johnson & Johnson vaccine to states and other jurisdictions each week, according to data from the CDC: 

About 4.5 million people have been vaccinated with the Johnson & Johnson vaccine, accounting for about 7% of people who are fully vaccinated in the US, according to the latest data from the CDC.
