San Luis Obispo County residents who received their first dose of the COVID-19 vaccine at one of the county's three mass vaccination clinics can now proactively schedule their second dose appointment.

Previously, those people were asked to wait to hear from the County Public Health Department before booking their second appointment. Now, residents who received their first dose at a county site can use the county's online second dose date calculator to determine when they'll be eligible for their second dose, then book their appointment up to one week in advance.

Second-dose appointments open every Wednesday by 9 a.m. for the following week.

People who received the Pfizer vaccine can book their second appointment three weeks after their first dose. Those who received the Moderna vaccine can book their appointments four weeks after their first dose.

Health officials say getting the second dose later than the recommended three or four weeks is not harmful and does not require re-starting the series of shots.

To sign up for a second dose appointment, visit or call the Phone Assistance Center at (805) 543-2444.

San Luis Obispo County has opened up vaccine eligibility to the following groups:

  • Residents 30 years of age and older
  • Residents at high risk because of certain severe medical conditions or disabilities
  • Education and child care workers
  • Emergency services workers
  • Food and agriculture workers
  • Public transit workers
  • Janitorial service workers
  • Health care and community health workers
  • Long-term care facility residents and staff
  • Residents who live or work in a homeless shelter or a behavioral health facility
  • Court system and jurors
