Southern Nevada Health District begins offering appointments for second dose of COVID-19 vaccine

January 25, 2021

LAS VEGAS – Starting this week, the Southern Nevada Health District will begin contacting people who are eligible to receive their second dose of the COVID-19 vaccine and were vaccinated at a Health District clinic to begin scheduling appointments. Second dose allocations are received based on the amount of first doses administered, and appointments will only be available for residents who received their vaccinations from a Health District clinic.

The Health District began administering the first doses of Moderna vaccine the week of January 4. The second dose can be administered after 28 days. The Health District began administering the first doses of Pfizer vaccine the week of January 18. The second dose of this vaccine can be administered after 21 days. Second dose appointment scheduling will begin the week of February 1. People eligible for a second dose appointment at the Health District will be notified using the contact information they shared at the time they received their first dose and will then be provided scheduling information. If someone who received their first dose from another non-Health District clinic schedules an appointment, they will not be vaccinated and advised to contact their original provider to receive their second dose.

The Health District is in the process of implementing a new registration and appointment system. As the new system is fully implemented, people will have the option to schedule their second dose appointment when they receive their initial vaccination.

It is recommended that the second dose of vaccine should be administered as close to the 21 and 28 intervals as possible. However, based on current guidance, second doses of both the Pfizer and Moderna vaccines can be administered up to six weeks after the first dose. The vaccines are not interchangeable.

Additional information about new COVID-19 vaccine is available on the Centers for Disease Control and Prevention website at www.cdc.gov/coronavirus/2019-ncov/transmission/variant.html. More information about COVID-19, including case updates, vaccination clinics, and available resources is available on the Health District website at www.SNHD.info/covid.
