Medical providers across Texas are receiving fewer doses of the Johnson & Johnson vaccine the week of April 12 than they did the week prior after manufacturing issues in a Baltimore plant caused supply to drop across the country.

The New York Times reported April 3 that 15 million doses of the Johnson & Johnson vaccine were ruined when a manufacturer mixed up ingredients between the Johnson & Johnson and AstraZeneca vaccines. According to a news release from the Texas Department of State Health Services, the Centers for Disease Control and Prevention has said smaller shipments will be coming to states until the plant in Baltimore is once again allowed to participate in production.

Austin-area providers are scheduled to receive 5,800 doses of the Johnson & Johnson vaccine this week—2,300 to Travis County providers, 3,300 to Hays County providers and 200 to Williamson County providers. Last week, hundreds of providers in those three counties received a total of 37,900 vaccine doses. An additional 100,000 Johnson & Johnson doses went to the DSHS central pharmacy warehouse for distribution across the state.

Despite the dip, more than 56,000 doses of vaccines are coming to providers in Hays, Travis and Williamson counties, roughly matching the weekly allocations through March before supply increased the week of April 5. That includes 12,000 doses to hub provider Austin Public Health and 3,510 to the Hays County Local Health Department.

According to DSHS data, as of April 11, 41.5% of Texans age 16 or older have received at least one dose of the vaccine. That total includes 38.4% of Hays County residents age 16 or older, 43.3% of Travis County residents age 16 or older, and 41.7% of Williamson County residents age 16 or older.
