Frequently Asked Questions

How much does it cost to get the COVID-19 vaccine

There is no charge. You will need to bring an ID and any insurance you use at your doctor office.

How many doses of the vaccine are needed?

Both Pfizer and Moderna vaccines require two shots to guarantee optimal results.
• If you received the Pfizer-BioNTech vaccine, you should get your second shot three weeks (or 21 days) after your first.
• If you received the Moderna vaccine, you should get your second shot one month (or 28 days) after your first.
• If you received the Johnson and Johnson, you do not need a second dose. It is a one-shot vaccine.

What if I miss the second dose of the vaccine?

You should get your second shot as close to the recommended three-week or one-month interval as possible. However, your second dose may be given up to six weeks (42 days) after the first dose, if necessary. You should not get the second dose earlier than the recommended interval.

If I have tested positive for COVID-19 and have recovered, do I need to be vaccinated?

Yes, even if you have already had COVID-19 you should be vaccinated. Experts do not yet know how long you are protected from getting sick again after recovering from COVID-19.

If I was treated for COVID-19 with monoclonal antibodies or convalescent plasma can I still get the COVID-19 vaccine?

You should wait 90 days before getting a COVID-19 vaccine

Are the vaccine candidates interchangeable?

For the Pfizer and Moderna, the same vaccine brand must be used for both shots. If the first dose of either of these vaccines were received, but a patient is unable to complete series with the same or different mRNA vaccine due to a contraindication then a single dose of Janssen COVID-19 vaccine may be administered at a minimum interval of 28 days from mRNA dose. These patients would be considered to have received valid, single-dose Janssen vaccination, not mixed vaccination series (mRNA/viral vector).

What is the difference between the different vaccines?

There are currently two types of authorized COVID-19 vaccines available in the U.S. They are mRNA vaccines by Pfizer and Moderna, and a viral vector vaccine by Johnson and Johnson.

Where will my vaccination information be recorded?

The vaccination provider will add your vaccination information to the state Immunization Registry system. This will ensure that you receive the same vaccine when you return for the second dose.
The Indiana State Department of Health (ISDH) maintains an Immunization Information System known as CHIRP (Children and Hoosier’s Immunization Registry Program). The purpose of CHIRP is to collect, forecast, manage, and share vaccine data to registered medical providers in Indiana.
In addition an individual also may access their personal or their dependents vaccine record from either the registered CHIRP provider or directly from the Indiana State Department of Health. ISDH has created the MyVaxIndiana Immunization Portal which enables a person to access a vaccine record from any computer.

After receiving the vaccine, when I am considered fully vaccinated?

In general, people are considered fully vaccinated:
• 2 weeks after their second dose in a 2-dose series, such as the Pfizer or
Moderna vaccines, or
• 2 weeks after a single-dose vaccine, such as Johnson & Johnson’s vaccine

If you do not meet these requirements, regardless of your age, you are NOT fully vaccinated. If you have a condition or are taking medications that weaken your immune system, you may NOT be fully protected even if you are fully vaccinated. Talk to your healthcare provider.

How do I report adverse effects from the vaccine?

1) After you receive a COVID-19 vaccine, you can enroll in a program called V-SAFE using your smartphone. V-safe is not an-app you download. V-safe is a secure smartphone-based tool that checks in on you after your COVID-19 vaccination.
Register at: .If you have any questions or problems enrolling in V-SAFE, you can call 800-232-4636 for help.
2) If you do not have a Smart phone, you can still report adverse effects by calling the VAERS (Vaccine Adverse Event Reporting System) toll-free information line at 800-822-7967 or by sending an email to

What is a RT-PCR test?

This is a molecular test used to determine if you are currently infected with COVID-19. It is done by a nasal swab, and then sent to a laboratory. Most people travelling outside the country will need this test done within 72 hrs prior to departure to prove they do not have COVID-19.

What is an Antibody test and how long to wait until it will detect them?

Antibody tests are used to look for evidence of past exposure to the SARS-CoV-2 virus or past COVID-19 infection. Most tests cannot detect antibodies until 11 to 18 days after the initial virus exposure. If tested prior to this, you may get a false-negative result. Antibody testing can be done by a finger-stick test to get a small blood sample, giving results in 5-10 minutes.

When do I get the second dose of Moderna?

The Moderna vaccine is given in 2 doses, 28 days apart. It can be given 4 days earier if necessary. And it can be given up to 42 days after the first dose.
