Novavax Vaccine

Story County Public Health will now administer the Novavax COVID-19 vaccine. This vaccine is not an mRNA vaccine - it is a protein subunit vaccine (this type of vaccine has been used for decades). This primary series is for previously unvaccinated people ages 18 and older. It is 2 doses, given 3-8 weeks apart.  People who are moderately or severely immunocompromised should also receive 2 doses, given 3 weeks apart (a 3rd primary dose is not currently authorized). Novavax vaccine is not authorized for use as a booster dose. 

Booster Shots

Booster Shots are now recommended by the CDC for all individuals aged 12 and over that received the primary series. Studies show after getting vaccinated against COVID-19, protection against the virus and the ability to prevent infection with variants may decrease over time and due to changes in variants.

Those age 18 and older may now choose which COVID-19 vaccine to receive as a booster shot. Some people may prefer the vaccine type that they originally received, and others may prefer to get a different booster. Pfizer or Moderna (COVID-19 mRNA vaccines) are preferred. Learn when individuals are eligible for a booster.

Third Dose

Third doses have been approved for certain immunocompromised individuals. This third dose is for immunocompromised individuals who have received either the Pfizer or Moderna two dose series. This third dose can be received 28 days after the second dose. Currently, the third dose recommendation only applies to mRNA vaccines, and does not include Johnson and Johnson. Learn more about COVID-19 vaccines for immunocompromised people.
