Iowa (KWWL) -- Starting Monday, all adults in the Hawkeye State will be eligible to get a COVID-19 vaccine.
Those 16 and older can receive the Pfizer vaccine and those 18 and older can receive the Moderna or the Johnson & Johnson vaccine.
The Iowa Department of Public Health said even though eligibility is open, it doesn't mean everyone will be able to sign up at once.
The Governor is asking people to be patient.
"Even though the vaccine at this point is increasing, there still won't be enough doses to vaccinate everyone immediately," Gov. Kim Reynolds said in a news conference on March 31. "It will take some time to work out the process again we're asking you to please remain patient."
Local health departments said as eligibility opens and vaccine production increases, so will the number of doses given to each county. Until then, many departments said they can only plan day by day.
In Dubuque, officials said they may see 54% more doses coming in this week.
"We don't have the opportunity to request how many vaccine doses we want," said public health specialist Mary Rose Corrigan. "We are simply allocated [doses] from the state. We expect to keep getting incremental increases as we move forward and as the state predicts."
Gov. Reynolds is urging people to get the vaccine as it becomes available.
"Getting vaccinated is the most important thing that each of us can do to ensure that our state's recovery from COVID-19 is both strong and sustainable," Gov. Reynolds said. "Pledge that you'll be vaccinated as soon as you can and encourage your family members, friends, and coworkers to do the same."
Last week, Gov. Reynolds said Iowa is fifth in the nation for vaccine administration. The Hawkeye State is set to get its largest allocation, at nearly 161,000 doses.
40% of Iowans 18 and older have received at least one dose, which is 17th in the nation. 85% of Iowans 65 and older have at least one dose.
