‘Never waste a dose’:How Larimer County health care providers give out extra COVID vaccines

How do I sign up to get a COVID vaccine when it’s my turn?

The Larimer County health department has online forms residents can fill out to be contacted when a vaccine appointment becomes available.

Individuals who qualify due to their age can fill out the form for themselves to be notified when a local provider has an appointment. 

Businesses that employ people who qualify for a vaccine, like health care workers or educators, are asked to complete the county’s COVID-19 planning survey to help providers coordinate vaccines. The county recommends people who qualify for the vaccine because of their profession to go through their employer.

Both forms can be found online at

All Larimer County vaccine providers use the same spreadsheet created from these form responses, Gonzales said.

I got my first dose of the COVID vaccine. Now what?

The Johnson & Johnson vaccine requires only one dose, and people are considered fully protected two weeks after they receive their shot.

If you got the Pfizer vaccine, you’ll need your second dose about 21 days after your first one. The Moderna vaccine’s second dose should be administered about 28 days after your first dose. 

According to the CDC, the second doses of these vaccines can be administered up to four days early or six weeks (42 days) later. 

Moderna and Pfizer vaccines both require two doses to be fully effective, but they are about 60% to 70% effective after the first dose, Larimer County Medical Director Chris Urbina said. 

After the second dose, both vaccines are about 95% effective at preventing severe illness due to COVID-19, Urbina said. People are considered fully vaccinated two weeks after their final dose of the vaccine.

For a comparison, Urbina said the annual flu vaccine is anywhere from 25% to 60% effective. 

I’m fully vaccinated against COVID. Do I still have to wear a mask?

Masks will still be needed for months as health officials work to distribute vaccines to the general public. 

State health department Chief Medical Officer Eric France said 70% of the state’s population will need to be vaccinated to reach herd immunity. At the current rate, France said the state could reach that by around Labor Day or sooner. But with so many unknowns about vaccine supply, France said it is hard to predict when we’ll reach herd immunity.

The CDC on March 8 released new guidance that said those who have received a full course of COVID-19 vaccine may get together with other fully vaccinated individuals in small groups inside their homes without masks or physical distancing.
