PMH Vaccine Clinic Rescheduled Due to Inclement Weather
PMH Vaccine Clinic Rescheduled Due to Inclement Weather

February 18, 2021

Due to inclement weather on the east coast, Prosser Memorial Health’s allocation of the Moderna vaccine has not yet shipped. This shipment was designated for the community vaccine clinic scheduled for this Saturday, February 20th.

As a result, we have rescheduled the community vaccine clinic for NEXT Saturday, February 27 from 8 am – 4pm. If you have an appointment scheduled for this Saturday, February 20, you will keep your same appointment time for next Saturday, February 27.

In regard to the maximum window to receive your second vaccine refer them to the CDC website:

Scheduling Doses

  • Persons age 18 years and older should receive 2 doses at least 28 days apart.

  • Second doses administered up to 4 days before the recommended date (24 or more days after first dose) are considered valid. However, doses administered earlier do not need to be repeated.

  • Second doses should be administered as close to the recommended interval as possible.

  • Do not use the grace period to schedule appointments for the second dose.

  • There is no maximum interval between the first and second dose.

  • Both doses should be Moderna COVID-19 vaccine.

  • The safety and efficacy of a mixed-product series have not been evaluated. Both doses of the series should be completed with the same product. However, if 2 doses of different mRNA COVID-19 vaccine products are inadvertently administered, no additional doses of either product are recommended at this time.

  • Administer the vaccine series alone. Do not administermRNA COVID-19 vaccine at the same time as other vaccines, and wait a minimum interval of 14days before or after administration of any other vaccine.

  • If mRNA COVID-19 vaccines are inadvertently administered within 14 days of another vaccine, doses do not need to be repeated for either vaccine.
