As of Tuesday, 178 health care workers employed by a Houston-based hospital system are on a two-week unpaid suspension after failing to meet the hospital system’s mandate to be fully vaccinated against COVID-19 by Monday, June 7.

Houston Methodist CEO Marc Boom announced the mandate in April, telling hospital staffers that if they failed to get vaccinated, they would be fired. The 178 suspended employees now have the two unpaid weeks to become fully vaccinated before termination. They can do so by getting the one-shot COVID-19 vaccine by Johnson & Johnson or a second dose of either of the two mRNA vaccines. Boom noted in a letter to employees sent Tuesday that 27 of the 178 suspended employees have received one dose of vaccine.

The Texas hospital system stood out in issuing the vaccination mandate. Many employers have shied away from mandates, though more employers have followed Houston Methodist’s lead in recent weeks. Overall, the mandate appears successful: about 97 percent of the hospital’s nearly 26,000 employees are fully vaccinated. Boom reported that 24,947 staffers were fully vaccinated, while 285 received a medical or religious exemption, and 332 were granted deferrals for pregnancy and other reasons.
