COVID-19 Vaccine Information

Obtaining a Vaccine

Starting March 29, 2021, individuals 16 and older in the state of Ohio, including those attending an Ohio college or university, can receive the vaccine. College students should use their student ID as proof of eligibility. The approved ages for each vaccine are:

  • Pfizer: ages 16 and older
  • Moderna: ages 18 and older
  • Janssen by Johnson & Johnson: ages 18 and older

Click here for information regarding U.S. Food and Drug Administration and Centers for Disease Control and Prevention pausing use of the single-dose Johnson & Johnson vaccine at federal sites and urging state sites to do so. In consultation with our medical advisory panel and in light of the governor’s new advice to pause these vaccines, we are pausing their use for our campus community.

Vaccine FAQs

In phase 3 clinical trials, the Pfizer-BioNTech vaccine was 95% effective against contracting symptomatic COVID-19. The Moderna vaccine was 94% effective against contracting symptomatic COVID-19. The Johnson & Johnson Janssen vaccine was 85% effective against contracting symptomatic COVID-19.

All vaccines have proven to be close to 100% effective in preventing severe illness and death attributable to COVID-19.

In speaking about the Moderna and Pfizer COVID-19 vaccines, Pope Francis said: "I believe that ethically everyone must take the vaccine. It is not an option; it is an ethical action, because you are playing with your health, you are playing with your life, but you are also playing with the lives of others." The Vatican's doctrinal office also has said it is morally acceptable for Catholics to take the vaccines.

Additional guidance comes from the U.S. Conference of Catholic Bishops, which has stated that receiving the COVID-19 vaccine "ought to be understood as an act of charity toward the other members of our community. In this way, being vaccinated safely against COVID-19 should be considered an act of love of our neighbor and part of our moral responsibility for the common good."

Additionally, the U.S. Conference of Catholic Bishops provide additional guidance regarding the Johnson & Johnson vaccine here: U.S. Bishop Chairmen for Doctrine and for Pro-Life Address the Use of the Johnson & Johnson Covid-19 Vaccine.

Catholic Cares, a coalition of U.S. Catholic organizations encourages the public to get vaccinated, provides information about the teachings of Pope Francis and U.S. Catholic Bishops on accepting the vaccine.


None of the emergency use authorized and recommended COVID-19 vaccines or COVID-19 vaccines in development in the United States contains the live virus that causes COVID-19, so a COVID-19 vaccine cannot make you sick with COVID-19.

However, some vaccinations may result in symptoms similar to COVID-19. These symptoms are a result of the vaccine teaching the immune system how to recognize and fight the virus, and are a sign the body is building protection against the virus that causes COVID-19.

It also is possible to be exposed and develop COVID-19 illness shortly after vaccination and before your body develops protective antibodies.

You may have mild side effects, including soreness or redness at the injection site. Other common short-term side effects are fever, chills, headache, tiredness and muscle or joint pain. These side effects are normal as your body creates an immune response to protect you from COVID-19, and may increase with the second dose.

Individuals who were infected with COVID-19 may experience some of these symptoms after the first vaccine dose.

It is recommended to drink plenty of water and eat something before your vaccination.

It typically takes a few weeks for the body to build protection against the virus that causes COVID-19 after vaccination. So it is possible someone could be infected with COVID-19 just before or just after vaccination and still get sick with the virus before you are fully immune.


According to the CDC, scientists are working to learn more about how easily variants might spread. Researchers and public health officials are studying whether variants spread more easily person-to-person, cause milder or more severe disease in people, are detected by viral tests, respond to medicines used to treat people for COVID-19, and/or change the effectiveness of COVID-19 vaccines.

The CDC's recommendations for slowing the spread of COVID-19 — wearing masks, staying at least 6 feet apart from others, avoiding crowds, ventilating indoor spaces, and washing hands often — also will also help prevent the spread of variants.


Neither the authorized and recommended vaccines nor the other COVID-19 vaccines in clinical trials in the United States should cause you to test positive on viral tests, which assess whether you have a current infection.​

However, you may test positive on some antibody tests, which indicate you had a previous infection and may have some level of protection against the virus. Experts are looking at how COVID-19 vaccination may affect antibody testing results. 


Yes, because of the severe health risks associated with COVID-19 and because reinfection with COVID-19 is possible. Plus, experts are unsure about how long someone who had COVID-19 will have natural immunity. The CDC is providing recommendations to federal, state and local governments about who should be vaccinated first.


CDC guidelines call for people who have been in close contact with someone who has COVID-19 to be quarantined, except for those who have had COVID-19 within the past three months (and have recovered) or who are fully vaccinated as long as they do not show or develop new symptoms.

Fully vaccinated means two weeks have elapsed after the second dose of a two-dose series, such as the Pfizer or Moderna vaccines, or two weeks after a single-dose vaccine, such as the Johnson & Johnson vaccine.


COVID-19 mRNA vaccines do not change or interact with your DNA in any way.

According to the CDC, based on current knowledge, experts believe COVID-19 vaccines are unlikely to pose a risk to a person trying to become pregnant in the short or long term. Furthermore, the CDC adds there is no evidence antibodies formed from COVID-19 vaccination cause any problems with pregnancy, including the development of the placenta. In addition, there is no evidence suggesting fertility problems are a side effect of ANY vaccine. People who are trying to become pregnant now or who plan to try in the future may receive the COVID-19 vaccine when it becomes available to them. Pregnant women have a higher risk of complications from COVID-19, so they are advised to discuss vaccination with their obstetrician.

The CDC also states mRNA vaccines are not thought to be a risk to the breastfeeding infant. People who are breastfeeding and are part of a group recommended to receive a COVID-19 vaccine, such as healthcare personnel, may choose to be vaccinated.

If you are planning to get a screening mammogram soon, you may wish to schedule that with the timing of the second dose of your vaccine in mind. Some experts recommend waiting until six weeks after the second vaccine dose. Consider consulting with your physician for more insight.  

Additional information can be found at the bottom of the CDC's "Myths and Facts about COVID-19 Vaccines" page and the CDC's "Vaccination Considerations for People who are Pregnant or Breastfeeding," plus by consulting with your primary care physician or specialist.


The COVID-19 vaccines available in the United States do not contain eggs, preservatives or latex. For a full list of ingredients, please see each vaccine's fact sheet for recipients and caregivers: 


Yes. Approximately 42% of participants in Pfizer BioNTech's worldwide clinical trials, 37% of the Moderna study population, and 26% of the participants in Johnson & Johnson's study were from minority communities, which is similar to the diversity of the U.S. at large.

In addition, clinical studies included participants age 65 and older (21% of Pfizer-BioNTech participants; 23% of Moderna participants) or 60 and older (34% of Johnson & Johnson participants); and those with high-risk chronic diseases, such as diabetes, severe obesity and cardiac disease (46% of Pfizer-BioNTech participants; 42% of Moderna participants; 41% of Johnson & Johnson participants).


Vaccinated persons who have been exposed to someone with suspected or confirmed COVID-19 are not required to quarantine if they meet all of the following criteria:

  • Are fully vaccinated (i.e., more than 2 weeks following your final dose of a one- or two-dose series).
  • Are within 3 months following receipt of the last dose in the series.
  • Have remained asymptomatic since the current COVID-19 exposure.

Persons who do not meet the above criteria should continue to follow UD quarantine guidance after exposure to someone with suspected or confirmed COVID-19 and must report their close contacts on the University's COVID-19 health reporting page.

Yes, to protect yourself and others, it will remain necessary after receiving the vaccine to continue following CDC and public health guidelines, which include wearing a face covering over your nose and mouth, staying at least six feet away from others, avoiding large gatherings and poorly ventilated spaces, and washing your hands often. 

It's important for everyone to continue using all the protective tools available as we learn more about how COVID-19 vaccines work in real-world conditions. Experts are looking at how many people get vaccinated and how the virus is spreading in communities. Experts also do not yet know whether getting a COVID-19 vaccine will prevent you from spreading the virus that causes COVID-19 to other people, even if you do not get sick yourself.

Employees should use sick time to get the vaccine, as well as for time taken because of an adverse reaction to the vaccine. Similar to reporting for a COVID-19 illness, report your sick time as you normally would and then contact Beth Schwartz, director of UD's benefits and wellness program, to replenish your charged sick time.

UD employees should use this form to report they've received their full COVID-19 vaccination and upload their vaccination record; this form needs to be completed to replenish your sick time.


UD students should use this form to report they've received their full COVID-19 vaccination and upload their vaccination record.

Faculty and staff are not required to report their vaccination. However, everyone reporting their full vaccination will help the University understand and manage more fully the pandemic on campus now and plan for the fall (e.g., to gauge how many on campus have some level of immunity and to help identify whether a "close contact" requires quarantining according to CDC guidelines for anyone fully vaccinated). However, if a UD employee requests that Human Resources replenish their sick time, then they must use this form to report their full COVID-19 vaccination and upload their record.


Yes. We will continue conducting surveillance testing in accordance with guidance from the Ohio Department of Health on surveillance testing for higher education.  


The University strongly encourages everyone on campus to be fully vaccinated. In addition to our commitment to the common good and the urgent need to protect vulnerable populations, we will assess the level of vaccination protecting our campus community as we make decisions about class size and gatherings in the fall.
