DENVER — The COVID-19 vaccine has arrived in Colorado and vaccinations are well underway.

We've received dozens of questions about the vaccine from viewers — including where, when and how to get it — and are answering them all below.

The state has a new 24/7 toll-free number to call with all vaccine questions. The number is 1-877-268-2926. About 200 operators — including Spanish speakers — work the line. As of Feb. 10, they are handling an average of 1,715 calls per day.

In early December, Colorado Gov. Jared Polis, along with state health officials, joined Anne Trujillo in a Denver7 COVID-19 Town Hall to answer your questions. Watch the town hall below:

      • Note: According to the CDC, not all immunosuppressed conditions point to a more severe outcomes with COVID-19, so not all immunocompromised individuals will get into an early phase. It depends on the specific condition. This may change based on CDC guidelines.
  • Phase 2 (expected to start late spring to early summer 2021): Anybody ages 16-59 not in a previous group

Government IDs or other identifying documentation is not required in Colorado — a directive aimed at ensuring non-citizens and others who might not have an ID are included in the vaccination drive.

The CDPHE says once it believes enough vaccines have been distributed to those who want it in one phase, it will move onto the next phase. The speed of this depends on the vaccine supply from the federal government.

You can keep track of how much vaccine the state is distributing by clicking here.

CDPHE Executive Director Jill Ryan said local public agencies and the CDPHE will let people know when the phases change and who will be eligible when. She said they encourage people to stay in contact with their primary care provider.

On. Jan. 5, the CDPHE sent formal guidance to Phase 1 vaccine providers better clarifying the priorities under Phase 1B.

The guidance said that local public health agencies should prioritize vaccinating any high-risk health care workers from Phase 1A and moderate-risk health care workers and first responders in Phase 1B, then move onto the rest of the Phase 1B group involving people age 70 and up. Hospitals, health systems, pharmacies and other clinics will provide vaccines to that group.

The CDPHE said that providers should ensure no dose is wasted and if a person misses an appointment, the vaccine should still go in somebody's arm, even if that individual isn't in the current phase.

“If faced with a choice of wasting vaccine doses or vaccinating someone earlier, providers should choose to vaccinate someone earlier,” the CDPHE said in a news release.

Gov. Polis released the updated timeline for phases 1B.3 and 1B.4 on Friday, Feb. 26.

Where can I get the vaccine?

Most recipients in Phase 1A will get the vaccine from their employer, local public health agency or through the federal government's Pharmacy Partnership for Long-term Care (LTC) Program. Those who qualify for the various parts of Phase 1B, including Colorado residents 70 years old and up, can call their local hospitals or drive-through clinics to ask about getting the vaccine once it is available at those locations, which started happening around Jan. 15. Many medical facilities are offering wait list sign ups.

Below, you can find the latest information on how to get your vaccine through a medical provider, Walmart, Sam's Club, King Soopers, City Market and by county. You can also use to serach for an appointment near you.

Other options:

  • Walmart and Sam's Club: Starting Feb. 12, Walgreens started vaccinating eligible Coloradans. Click here for participating locations. To sign up, you first must be eligible through state guidelines. Then you simply go to Walmart's or the Sam's Club sign up website.
  • King Soopers and City Market: King Soopers said some its pharmacy locations will start offering the COVID-19 vaccine to eligible Coloradans through the federal retail pharmacy program. City Market locations in Colorado will also be among the pharmacies offering the vaccine. Reservations are required for the vaccine, and only eligible Coloradans will be allowed to sign up. Sign up by clicking here. The companies are working on putting a list together of participating locations.

On Jan. 23, the state held its first large-scale drive-thru vaccination clinic at Coors Field with UC Health, and 1,000 people were vaccinated that weekend and 10,000 people were scheduled the following weekend. Denver7 will report on any future mass vaccination sites here.

All eligible Coloradans can get the vaccine anywhere in the state, regardless of their residence, Gov. Polis said. Anybody who is turning these individuals away based on where they live will receive a warning from the state.

The state said they are working with local public health agencies across the state to create a vaccine rollout program for individuals who are homebound. In a similar fashion, the CDPHE partnered its Vaccine Support Team with local public health agencies to get the flu vaccine to those people in 2020. The Johnson & Johnson vaccine doesn't need to be refrigerated, so it could easily be brought straight to someone's home and administered to a homebound person.

Information on providers for Phase 2 and 3 will be available closer to the spring, but members in those groups can sign up through the state's health are providers to receive alerts and get on a wait list.

Vaccines are not sold over the internet — if you see one, it's a scam.

How much will it cost?

The vaccine is free to all Coloradans, no matter if they have insurance or not. Colorado providers are not allowed to turn away a person who cannot pay for the vaccine.

However, vaccination providers will have the ability to charge an administration fee for administering the shot. Providers can get this fee reimbursed by the patient’s public or private insurance company, or by the Health Resources and Services Administration’s Provider Relief Fund if the patient is uninsured.

Medicare, Medicaid, and private insurance are required to cover the cost of the COVID-19 vaccines.

When will I gain immunity from the virus?

Gov. Polis says the 95% immunity won't come into play until a month or a month and a half after the first vaccine is administered to an individual. By this time, the person will have had both vaccines, plus 10 days for their body to develop the immune response to fight off the virus.

The CDC says it typically takes a few weeks for the body to build immunity after a vaccination. It's possible that a person may become infected with the virus shortly after getting the vaccine because the body has not had enough time to provide protection, however it will likely be much more mild than it would have been if the person wasn't vaccinated, according to Dr. Richard Zane, who is leading UCHealth's novel coronavirus response and vaccination efforts.

Pfizer reported that its COVID-19 vaccine starts to work just 10 days after the first dose, but immunity likely won't be attained after the second dose.

Polis said if there's a shortage of second doses for individuals, they will use some first doses for others as second doses for those in need. However, this is not expected.

How long will the vaccine protect me? Will this be a yearly vaccine, like the flu shot?

It could be several months until researchers will know how long vaccinated people are protected.

Can a vaccinated person pass the virus on to other people?

Possibly. This sometimes happens to people who have had the flu shot, though at much lower rates than an unvaccinated person. Dr. Richard Zane, who is leading UCHealth's novel coronavirus response and vaccination efforts, said vaccinated individuals should still continue to social distance, wear masks and wash their hands regularly.

Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital, told Denver7 during a Facebook Live Q&A that, "because the vaccine is not 100% effective in preventing disease, you can get a mild infection or display no symptoms of COVID-19 even after vaccination and you could potentially transmit the virus to other people."

If my first vaccine is from one manufacturer, does my second vaccine need to be from there too? Do I need to get the vaccine at the same place both times?

The FDA says if you receive one dose of the Pfizer-BioNTech COVID-19 vaccine, you should receive a second dose of this same vaccine three weeks later to complete the vaccination series. The same goes for the Moderna vaccine.

The CDPHE recommends getting both vaccines at the same provider. Due to a limited supply, the provider will need to place an order for your second dose after administering the first one. This process ensures the state's weekly allocation from the federal government will have enough second doses of the same product at the right time.

Does the vaccine work against COVID-19 variants?

The CDC said scientists are working to learn more about whether currently authorized vaccines will protect people against COVID-19 variants. Currently, there is no evidence that these variants cause more severe illness or increased risk of death, however they appear more contagious.

The CDC said as of late December, there is no evidence that the variants will change the effectiveness of the vaccine. There isn't any reason to believe this is happening, the CDC said, and most experts believe it's unlikely because of the nature of the immune response to the virus.

What's the difference between the vaccines?

While the vaccines are similar, there are a few differences. The most important one is the way they are stored. While the Pfizer vaccine must be stored at -75 degrees Celsius (-103 degrees Fahrenheit), the Moderna vaccine can be stored at -20 degrees Celsius (-4 degrees Fahrenheit). The latter is about the same temperature as a home freezer.

In addition, the Pfizer vaccine can be placed in a refrigerator for only five days maximum before it expires. The Moderna vaccine can be kept in a refrigerator for up to 30 days.

The Pfizer vaccine is authorized for people 16 years old and older. The Moderna vaccine is available for people 18 years old and up.

Lastly, the two doses of each vaccine is slightly different. Pfizer's vaccine is two 30 micrograms each, given 21 days apart. Modern's vaccine is two 100 micrograms each, administered 28 days apart.

The AstraZeneca COVID-19 vaccine is showing about 76% effectiveness after the first dose and 82% after the full two doses.

The Johnson & Johnson COVID-19 vaccine, created by their pharmaceutical group called Janssen, is reporting 85% efficacy for their single-dose vaccine. This is the only one-time vaccine candidate.

Dr. Ross Kedl, a professor of immunology and microbiology at the University of Colorado Anschutz School of Medicine, said the Janssen vaccine uses viral vector technology, meaning the vaccine is made from an inactivated adenovirus that will be able "infect" the cells but not replicate itself.

Both AstraZeneca and Johnson & Johnson vaccines do not require the super cold temperature that the Pfizer and Moderna vaccines need. This means these vaccines may do better in transportation to more rural areas of the country.

The Johnson & Johnson and AstraZeneca COVID-19 vaccines use viral vector technologies, not mRNA, unlike the Pfizer and Moderna vaccines.

Why should the public feel confident the COVID-19 vaccine is safe?

Dr. Richard Zane, leader of UCHealth's novel coronavirus response and vaccination efforts, says people should feel confident because of the way in which it was tested. Even though it was expedited — meaning the amount of time it took to make this vaccine, it is truly unprecedented — no corners were cut. It was essentially done with a lot more energy and money than has ever been done before. But it is highly effective — it has a 95% efficacy rate — and it was tested on tens of thousands of people.

Gov. Polis explained that if you have the chance to get the vaccine soon, it's a blessing.

"You're one of the most fortunate people in the world," he said, explaining how it won't reach millions of other people around the world for a year or two. "Please, when you have that chance, don't waste that opportunity by not getting protected by a deadly virus that has caused so much pain and suffering... We can end it. We have the tools thanks to modern science. All it takes is two pricks of a needle, 21 days apart."

Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital, told Denver7 during a Facebook Live Q&A had this to say about why the public should be confident in the vaccine:

"Most health experts have actually received the vaccine in order to protect themselves, their loved ones, and the patients they care for. I think that speaks volumes about how they view the safety profile of the vaccines. Additionally, at this point, almost everyone knows someone who knows someone who has had COVID-19. Talk to them about their experiences and they will tell you about the impact it can have on your health."

What are the side effects?

The side effects that have been reported are minor and commonly associated with first vaccines, Dr. Richard Zane said. This includes muscle aches, pain at the sight of the injection and low grade fever for less than 24 hours. Some people have reported nausea and diarrhea. And most of the people who have reported the symptoms felt better after taking Tylenol or Motrin.

These side effects are a sign that the vaccine is working as your body builds and remembers defenses against a future attack. While these effects have been reported more with the second dose, some people see stronger symptoms with the first dose, or not at all.

Dr. Nicholas Tsipis with Swedish Medical Center said overall, the benefits outweigh these symptoms. The side effects should only last 12 to 24 hours, he said. If you have a long-lasting high fever,dehydration, profound fatigue or can't keep food down, call your doctor.

The most severe reaction that people can experience after taking the vaccine is anaphylaxis (a severe allergic reaction) and this typically occurs within 15 minutes of administration, according to Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital. Other reactions are typically milder and can include fatigue, fever, headache, muscle and body aches, and occasionally rash, she said, adding these symptoms typically last less than 24-48 hours.

If the FDA and CDC see new serious side effects from the virus, the vaccine may be removed from the market.

Is it OK to take aspirin or Benadryl before the shot, especially the second one?

Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital, says it is recommended that you avoid taking anything other than routine medications before your shot.

If you do develop a reaction after the either the first or second shot, she said, you can take medications at that time for the symptoms but you might want to be sure that your provider has no concerns tylenol, ibuprofen, or an antihistamine interacting with you current medications.

If someone has already had COVID-19, do they need the vaccine?

Dr. Richard Zane as well as the CDC say yes. However, if you are currently symptomatic with COVID-19, you should wait until symptoms have abated.

Currently, there is not enough information available to say if or for how long after infection someone is protected from getting COVID-19 again, according to the CDC. Early evidence shows natural immunity may not last very long, according to the CDC. The World Health Organization says available data suggests that most people who recover from COVID-19 develop an immune response that provides some period of protection against reinfection, but researchers aren't sure how strong the protection is or how long it lasts. There have been cases of reinfection.

How long will it take to get enough people vaccinated before we see an impact?

Dr. Richard Zane, who is leading UCHealth's novel coronavirus response and vaccination efforts, says we will likely see impact when 30% or 40% of the population is vaccinated. But the number to get herd immunity is over 50% or more ideally, 60 or 70%.

Gov. Polis said as long as we reach a "reasonable" amount of the population that has the 95% level of protection, the pandemic will be over. That doesn't mean nobody will ever get COVID-19 again — just like how today people still get measles and mumps — but it will be rare and there's no concern for overwhelming health care facilities.

Should I get the vaccine if I have allergies? What about autoimmune issues?

A very small number of people who have a history of severe allergic reactions to injectables or the contents of vaccines should not get the COVID-19 vaccine, said Dr. Eric France, chief medical officer for CDPHE.

But if you have other allergies — a food allergy, bee sting allergy, latex allergy — you should get it, France said, even if the allergy is serious. He said the person who administers the vaccine may ask you to stay at the facility for about 30 minutes to ensure you do not have a bad reaction.

There is no correlation between reactions to other medications, such as Stevens-Johnson syndrome and these vaccines, according to Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital. If you have had a severe reaction to medications or other things in the past, she said, let your vaccinator know and they will plan to monitor you a little longer after the vaccine is administered.

Individuals with autoimmune issues should talk to their doctor about their interest in the vaccine so the doctor can review their medical conditions. But as of now, the only conditions under which a person should not get the vaccine is if they have a severe allergy to the vaccine's contents or if they're under the age of 16.

Do we really need the vaccine if we’re wearing masks and socially distancing?

The CDC says stopping a pandemic requires using all the tools available.

“Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed,” the CDC says on its website. “Other steps, like covering your mouth and nose with a mask and staying at least 6 feet away from others, help reduce your chance of being exposed to the virus or spreading it to others.”

Can family members of a high-risk person get the vaccine early too?

No. The CDPHE says until a vaccine is widely available, they must prioritize health care providers and those most at risk of getting severely sick or dying.

Do the COVID-19 vaccines use the live virus?

According to the CDC, none of the COVID-19 vaccines currently in development in the United States use the live virus that causes COVID-19. The vaccines contain the gene for a virus protein only — it provides a body with the tools needed to fight the virus if a person is infected. The CDPHE says it is not possible to get COVID-19 from the vaccine.

How can I prove I received the first COVID-19 vaccine to get the second?

According to the CDC, you should receive a vaccination card, which will tell you what vaccine you received, when and where. Keep this handy, as you'll need to show it to receive your second vaccine. It's very important to receive the second dose on time.

What happens if I skip the second dose of the vaccine?

The worst case scenario of skipping the second shot is that the expanded timeframe could allow the virus to spread and mutate, and potentially build resistance to the vaccines, according to Penn State University biologist David Kennedy. However, that outcome is unlikely, though the World Health Organization announced Dec. 14 that it detected a new variation of the virus in England, showing the virus is already mutating without the evolution pressure of a mass vaccine program. In late December, the variant was confirmed in Colorado.

Vaccine expert Dr. Paul Offit said a person who gets the first vaccine but not the second would likely have as short-lived but incomplete protection. Therefore, it is vital to get the second dose.

During a Facebook Live Q&A, Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital, said you have up to six weeks to get the second dose in case you miss your appointment.

How will the vaccine impact the mask mandate? Should I still wear one?

In short: Yes, you should still wear a mask. Both the Pfizer and Moderna vaccine require two shots — Pfizer’s is three weeks after the first one and Moderna’s is four weeks. The effects of the vaccines are not immediate. It will not kick in until a couple weeks after the second shot, according to CDPHE COVID-19 Incident Commander Scott Bookman.

There is not enough information available yet to determine when the CDC will stop recommending that the public wear masks.

The CDC announced on March 8 that people who are fully vaccinated can safely visit with other vaccinated people, and small groups of unvaccinated people in certain circumstances, but there are still safety precautions to take.

What are all the ingredients in the vaccines, even the inactive ones?

According to the FDA, the ingredients in the Pfizer vaccine are as follows: mRNA, lipids ((4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate), 2 [(polyethylene glycol)-2000]-N,N-ditetradecylacetamide, 1,2-Distearoyl-sn-glycero-3- phosphocholine, and cholesterol), potassium chloride, monobasic potassium phosphate, sodium chloride, dibasic sodium phosphate dihydrate, and sucrose.

According to the FDA, the ingredients in the Moderna vaccine are as follows: mRNA, lipids (SM-102, polyethylene glycol [PEG] 2000 dimyristoyl glycerol [DMG], cholesterol, and 1,2-distearoyl-sn-glycero-3-phosphocholine [DSPC]), tromethamine, tromethamine hydrochloride, acetic acid, sodium acetate, and sucrose.

According to the FDA, the ingredients in the Janssen (Johnson & Johnson) vaccine are as follows: recombinant, replication-incompetent adenovirus type 26 expressing the SARS-CoV-2 spike protein, citric acid monohydrate, trisodium citrate dihydrate, ethanol, 2-hydroxypropyl-β-cyclodextrin (HBCD), polysorbate-80, and sodium chloride.

The AstraZeneca vaccine has not yet received emergency use authorization from the FDA.

What conditions are considered high risk for COVID-19 that could get me early vaccination?

The CDC has said that people who are at high risk for severe COVID-19 illness due to underlying medical conditions, regardless of their age, will be able to get the vaccine early.

In this case, "underlying medical conditions" means any severe illness or condition that a person has that would, if they contract COVID-19, require hospitalization, intensive care, or a ventilator to help them breathe, or that they may even die. This includes the following, according to the CDC:

  • Cancer

What about children, or pregnant or breastfeeding women? Will it have an effect on fertility?

The clinical trials for Pfizer’s vaccine were conducted on people over the age of 16. Younger kids and pregnant women were not included. Dr. Anthony Fauci said clinical trials to test the vaccine safety on those two groups could begin in January. Children represent about 7% of confirmed COVID-19 cases in the United States.

Modern began testing the vaccine in atrial with teenagers on Dec. 10.

On Dec. 30, Gov. Polis said information on vaccines for children likely won’t be available until the summer.

Dr. Eric France, chief medical officer for the CDPHE, said women should be talking with their health care providers to see if they should consider the vaccine given the rate of COVID-19 in their community.

Currently, there is no data about the safety or efficacy of the vaccine on pregnant or breastfeeding women, or its impact on fertility. There are also no reports that have shown an association between the COVID-19 vaccine and infertility, according to Dr. Michelle Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital.

Will the vaccine become mandatory in Colorado?

As of now, the state is not considering a COVID-19 vaccine mandate. Business owners cannot require patrons to prove they've been vaccinated — that's customers' protected health information.

Airlines or cruise lines may have something like this, but the state of Colorado doesn't not have any plans to make this vaccine mandatory, Gov. Polis said, just like how shots for measles and mumps are also not mandatory, though highly recommended.

"They're the right thing to do. They're the way to protect yourself, but nobody is going to come and stab you in the arm without your permission," Polis said.
