COVID-19 Boosters

Why do people need a booster?
Studies show that after getting vaccinated against COVID-19, protection against the virus may decrease over time and less able to protect against new variants.

Who is eligible?
The following are eligible to receive a COVID-19 booster:

  • People who received a Johnson & Johnson vaccine at least two months ago
  • People who received a two-dose Pfizer or Moderna series at least six months ago and fall into any of these eligible groups:
    1. 65 years and older
    2. Age 18+ who live in long-term care settings
    3. Age 18+ who have underlying medical conditions
    4. Age 18+ who work or live in high-risk settings
    5. Immunocompromised people who received their single-dose Johnson & Johnson vaccine or the second shot of their Pfizer or Moderna series at least 28 days ago

What does it cost?
The booster doses are free of charge to anyone who meets the eligibility criteria.

Where can I get my booster?
The University Health Center Pharmacy will offer the 2023 COVID-19 booster, please check back for updates in mid-October. You can also find off-campus locations that offer the booster by searching

Do I have to get the same vaccine as my original type?
You may choose which vaccine you receive as a booster dose. Some people may have a preference for the vaccine type they originally received. Others may prefer to get a different booster. The CDC allows this type of mix-and-match dosing for booster shots.

Does this change who is considered fully vaccinated?
The definition of fully vaccinated has not changed. If you have completed your two-dose Pfizer or Moderna series or the one-dose Johnson & Johnson vaccine, you are still considered fully vaccinated.

Common Questions

How can I get a copy of my vaccination card?

If you've already been vaccinated, you should have received a COVID-19 vaccination card at the time of your initial immunization. If you lose your card, you can also access your Nebraska vaccination records through the Nebraska State Immunization Information System (NESIIS). You can also call the Information Line, 402.444.3400, available 8:30 a.m. to 4 p.m. Monday through Saturday. If you are having trouble accessing your vaccination records through NESIIS, please consult your vaccine provider for assistance. NESIIS also has a Help Line at 888.433.2510 or can be reached by email at (Note -- If you were vaccinated outside of Nebraska, you’ll need to contact that state or vaccine provider).

How much does the vaccine cost?

The COVID-19 vaccine is free to most citizens. Vaccine distributors can charge an administration fee for giving the shot to someone. However, in most cases, public and private insurance providers cover this cost. We are not billing patients for COVID-19 vaccines received at Nebraska Medicine locations, including the University Health Center, and we do not profit from COVID-19 vaccinations.

Why do we need COVID-19 vaccines?

COVID-19 infections can be a minor inconvenience, or they can lead to severe disease and death. Social distancing, handwashing and wearing your mask certainly help. However, the best way to stop this virus is to generate COVID-19-specific immunity within our community.

We can achieve this immunity in one of two ways: through illness (natural herd immunity) or through vaccination. Since illness leads to severe disease or death for many, a safe and effective vaccine is a much better alternative.
