ANNAPOLIS (WJZ) — All state mass vaccination sites will transition to direct scheduling starting May 1.

All eligible Marylanders will be able to go online and book their own appointments, or call 1-855-MD-GOVAX.

To prepare, they are ending pre-registration Thursday. By the end of Friday, anyone who has already pre-registered will be contacted for an appointment.

If you want to just go without one, you can go to the nine mass vaccination sites that are walk-up or drive-thru options.

For those who need help getting to a site, call their vaccine support call center at 1-855-MD-GOVAX and they will connect you directly with a vaccinator.

The state is also reserving blocks of appointments for university students and major employers.
