Memorial Hermann is pleased to offer free COVID-19 vaccination to community members across Greater Houston. To provide additional, convenient access to the vaccine, first- and second-dose walk-ins are now being accepted at select Memorial Hermann hospitals and clinics for individuals 5 years of age and older. Additionally, Memorial Hermann is offering a third primary series dose of the Pfizer or Moderna COVID-19 vaccines to individuals whose immune system is moderately to severely compromised. Learn more about boosters here »

Please note: Minors (individuals 5 through 17 years of age) will be required to have an adult accompany them to their vaccination appointment. In addition, should individuals need assistance receiving vaccination, one caregiver may accompany them to their appointment.

Memorial Hermann locations administering the Moderna vaccine will only vaccinate individuals 18 years of age and older.
