The first batch of the Johnson & Johnson COVID-19 vaccine is in Iowa. Marion County health leaders said the Johnson & Johnson vaccine has arrived there.The state is being very specific with each of the 17 counties receiving the new vaccine. The state wants shots to go in the arms of food manufacturing workers first.The county has received 300 doses of the new vaccine. They're one of the handful of chosen counties that all have significant Phase 1B - Tier 2 populations.There is also an emphasis on getting these shots to the rural parts of the state. That's because the Johnson & Johnson vaccine, also known as the Janssen vaccine, is a game changer, both for health and logistical reasons. It's a single shot, and it doesn't require extensive refrigeration.Marion County Public Health Director Kim Dorn says Marion County has only been receiving the Moderna vaccine, so this will make an impact for them."Only having to make one trip to get everybody vaccinated, it saves on staff time, it saves on resources and of course gets them to protection quicker," Dorn said.The first doses will go to Hormel Foods in Knoxville.Dorn says it'll be much simpler to give out, since it's one dose, and does not require ultra-cold freezers."We're really pleased that we get another chance for additional doses. It's just really beneficial to get as much vaccine in the community as we can," Dorn said.Marion County is getting clinics set up to get the Johnson & Johnson shot into arms over the next two days.On Friday, they're having their largest vaccine clinic ever at the Vermeer Pavilion in Pella. They'll administer 500 prime doses, and 200 booster doses of the Moderna vaccine.To get info on that, head to marionph.org/covid-19-information.Find out how you can get vaccinated in Iowa here.
