*COVID-19 vaccine information: As of April 5th, all Nevadans aged 16+ are eligible to schedule a vaccine appointment. Visit to find a vaccine location or call the Vaccine Helpline at 1.800.401.0946 for assistance finding an appointment. The Vaccine Helpline is available seven days a week between 7AM to 8PM.



Racial minorities and other vulnerable populations have been disproportionally affected by the COVID-19 pandemic. Reducing the impact of COVID-19 in our communities requires a collective effort to ensure those who want the vaccine can get one. Also, it is equally essential to ensure our communities have access to reliable and accurate information that can assist them with making an informed decision about vaccination. We commit to regularly updating our content to ensure vaccine questions are being answered.

The COVID-19 vaccine is a crucial component to helping Nevadan’s go back to work and school, as well as return to social events with family and friends. If enough Nevadans get vaccinated, we will slow the spread of COVID-19, which will help our businesses, restaurants, schools, and casinos return to in-person operations.

Although Nevadans are getting vaccinated, it is still important to continue following preventative measures such as social distancing and mask wearing. Social distancing and mask wearing help reduce exposure to the virus, while the vaccine teaches your body to fight the virus if exposed. All three are needed to slow the spread of COVID-19.

Vaccine FAQs 

What COVID-19 vaccines are currently available?

As of April 12, 2021: Three vaccines have been approved for use in the U.S. Pfizer-BioNTech, Moderna, and Jannsen (Johnson & Johnson), but more COVID-19 vaccines are still under development.

  • Pfizer-BioNTech COVID-19 Vaccine, two dose series, approved for ages 16+
  • Moderna COVID-19 Vaccine, two dose series, approved for ages 18+
  • Janssen (Johnson & Johnson) COVID-19 Vaccine, single dose, approved for ages 18+

Are COVID-19 vaccines safe?


The U.S. Food and Drug Administration (FDA) can grant Emergency Use Authorization (EUA) for COVID-19 vaccines that show to be safe and effective as determined by data from the manufacturers and findings from large clinical trials. The data demonstrates the known and potential benefits of the vaccine outweigh the known and potential harms of COVID-19 infection.

The COVID-19 vaccine clinical trials included tens of thousands of participants. These trials generate scientific data and other information that the FDA can use to will be determine vaccine safety and efficacy.

There are several vaccine safety monitoring systems in place once the vaccine is authorized for use. These monitoring systems watch for adverse events (aka possible side effects) following vaccination. If an unexpected adverse event occurs, medical experts and doctors will further assess the event to determine if it is a true safety concern. Experts then decide whether changes are needed in U.S. vaccine recommendations. This monitoring is critical to help ensure that the benefits continue to outweigh the risks for people who receive vaccines.

How do we know the vaccines are safe and effective for minority communities? 

COVID-19 vaccines were tested in large clinical trials to make sure they meet safety standards since COVID-19 can affect anyone. Medical experts and doctors ensured participants in the vaccine clinical trials represented different races, ethnicities, genders, ages, and health conditions.

  • The Pfizer-BioNTech clinical trial included over 43,000 participants and approximately 42% came from diverse backgrounds. More specifically, 26.2% identified as Hispanic, 9.8% African American, 4.4% Asian, and 3.3% other. Learn more about Pfizer-BioNTech here.
  • The Moderna clinical trial included over 30,000 participants and approximately 36.5% came from diverse backgrounds. More specifically, 20% identified as Hispanic, 9.7% African American, 4.7% Asian, and less than 3% other. Learn more about Moderna here.
  • The Janssen (Johnson & Johnson) clinical trial included roughly 45,000 participants. More than 45% of the participants identified as Hispanic. Also, 17.2% of participants were African American, 8.3% American Indian or Alaska Native, 3.5% Asian, and 5.4% multiracial.

How did the COVID-19 vaccine get developed so quickly?  

The COVID-19 vaccines were developed through a worldwide effort, massive funding, and existing research. The vaccines were carefully evaluated through clinical trials and met safety standards before being authorized by the Federal Drug Administration (FDA).

How do mRNA vaccines (Pfizer-BioNTech and Moderna) work?

Messenger RNA vaccines—also called mRNA vaccines—are some of the first COVID-19 vaccines authorized for use in the United States. mRNA vaccines are a new type of vaccine to protect against infectious diseases. To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, they teach our cells how to make a protein—or even just a piece of a protein—that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.

  • They cannot give someone COVID-19: mRNA vaccines do not use the live virus that causes COVID-19.
  • They do not affect or interact with our DNA in any way: mRNA never enters the nucleus of the cell, which is where our DNA (genetic material) is kept. The cell breaks down and gets rid of the mRNA soon after it is finished using the instructions.
    mRNA Vaccines Are New, But Not Unknown: Researchers have been studying and working with mRNA vaccines for decades. As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine.

How do vector viral vaccines (Janssen) work?

The Janssen (Johnson & Johnson) is a viral vector vaccine. This type of vaccine uses a different kind of virus that is weakened and live to deliver a set of instructions from the COVID-19 virus to your cells. The instructions show your body how to make a protein found on the COVID-19 virus, which will trigger the desired immune response. Your body will then produce antibodies that will protect you from the real virus if you get infected. Learn more about viral vector vaccines here.

Do the vaccines give you COVID-19?

No. None of the authorized COVID-19 vaccines use the live virus that causes COVID-19. This means you cannot get COVID-19 from the vaccine. Learn more about the COVID-19 vaccines here.

Does the mRNA vaccine change your DNA?

No. None of the authorized COVID-19 vaccines can alter your genetic makeup (DNA). The Pfizer-BioNTech and Moderna vaccines do use mRNA. However, mRNA is unable to change your DNA because it cannot enter the nucleus of your cells, which is where your DNA lives in your body. This means mRNA does not interact with your DNA, therefore it cannot change it. Learn more about mRNA vaccines here.

Does the vaccine protect against other strains of COVID-19?

Current studies suggest the authorized COVID-19 vaccines are effective against other strains (also known as variants) of the virus. However, additional research is needed to further assess. Learn more about COVID-19 variants here.

Who should and should not get the vaccine?
