Yes. Although it is rare, it is possible to be infected after being fully vaccinated. (Date Added: 4.19.21)

No, with some exceptions. Fully vaccinated people with no COVID-like symptoms do not need to quarantine or be tested following an exposure to someone with suspected or confirmed COVID-19, as their risk of infection is low, except for those living in congregate housing such as dormitories and group homes.

UofL Health is administering the Moderna, Pfizer and Johnson & Johnson vaccines. When UofL Health sends you a vaccination invitation, they will not able to confirm which vaccine you’ll receive due to the limited vaccine supply. The brand of vaccine they administer to you at your first appointment, however, will be the same one they administer at your follow-up appointment for the second dose. (Date Updated: 4.05.21)

The federal government distributes the COVID-19 vaccine to each state based on its population. It is up to each state to coordinate the distribution within each state.Kentucky’s state vaccination plan can be found online, here. (Date Updated: 3.5.21)

Initially, COVID-19 vaccines were made available for healthcare personnel who are at the highest risk of exposure to the virus, such as those providing direct care to COVID-19 patients and nursing home patients. As more doses of the vaccines become available, other groups will become eligible for the vaccine. UofL Health is the university’s designated vaccine administrator and works with the State of Kentucky on when each phase of the plan is rolled out. UofL Health will prioritize university members according to the State of Kentucky’s plan, which is as follows:

  • Phase 1A: Long term care facilities, assisted living facilities and healthcare personnel
  • Phase 1B: First responders, anyone 70 or older, K-12 school personnel
  • Phase 1C: Anyone 60 or older, anyone age 16 or older with CDC highest Rick C19 conditional, all essential workers (this includes university staff & faculty)
  • Phase 2: Anyone over the age of 40
  • Phase 3: Anyone 16 or older
  • Phase 4: Anyone under the age of 16 if the vaccine is approved for this age group

According to CDC, people who are pregnant, breastfeeding, and part of a group recommended to receive the COVID-19 vaccine may choose to be vaccinated. While breastfeeding is an important consideration, it is rarely a safety concern with vaccines. No data are available yet on the safety of COVID-19 vaccines in lactating women or on the effects of mRNA vaccines on breastfed infants or on milk production/excretion. The mRNA vaccines are not thought to be a risk to breastfeeding infants. To make sure more information is gathered regarding the safety of these vaccines when administered during pregnancy, pregnant people are encouraged to enroll in v-safe, CDC’s new smartphone-based tool being used to check-in on people’s health after they receive a COVID-19 vaccine. If pregnant people report health events through v-safe after vaccination, someone from CDC may call to check on them and get more information. Additionally, pregnant people enrolled in v-safe will be contacted by CDC and asked to participate in a pregnancy registry that will monitor them through pregnancy and the first 3 months of infancy. If you have questions about getting vaccinated, talking with a healthcare provider may help you make an informed decision.

Yes. COVID-19 vaccine clinical trials included diverse and underrepresented groups. (Date Added: 12.15.20)

As COVID was only identified in December 2019 and these are new vaccines, the long-term effects of the vaccines are unknown at this time. (Date Added: 12.15.20)

The most common side effect caused by the COVID vaccines include: (1) pain at the site where the vaccine was given, (2) headache, (3) fever, (4) chills or (5) muscle aches. Side effects are generally worse after receiving the second dose. (Date Added: 12.15.20)

If you have side effects from the COVID-19 vaccine and are unable to work, you must remain home until the side effects subside. During this time, you may:

  • work from home (if able and approved by supervisor) or
  • use accrued sick, vacation or personal leave (if any available); or
  • be placed on unpaid leave (if all other leaves exhausted)

Please Note: If an employee is absent for more than seven days, they may be eligible for FMLA. If they qualify for FMLA, staff may apply for shared leave after all leave balances are exhausted. (Date Added: 1.13.21)

No. You will not test positive on nose, throat or saliva tests because of the vaccine. You may positively test if you have an antibody test from a blood test. Having positive antibodies to COVID-19 does not mean that you are infected with COVID-19. Antibody testing following the completion of the vaccine series is not recommended to confirm response to the vaccine. (Date Added: 12.15.20)

No, it is not possible to get COVID-19 from vaccines. Vaccines against SARS-CoV-2 use inactivated virus, parts of the virus (e.g. the spike protein), or a gene from the virus. None of these can cause COVID-19. (Date Added: 12.15.20)

Even if you have previously tested positive for COVID-19, you should still consider getting the vaccine. The vaccine protects against several strains (types) of the pathogen and can still be valuable. (Date Added: 12.15.20)

The vaccines currently available under the Emergency Use Authorization all require two doses over a three-week period. (Date Added: 12.15.20)

Currently, there is no data regarding the efficacy of only receiving one dose of vaccine. We do not know the exact effects from only receiving one dose of a COVID-19 vaccine, but it is believed that the efficacy of the vaccine would be reduced. (Date Added: 12.15.20)

Following the completion of the two-dose vaccine series, it is unknown if booster doses will be necessary.The CDC has made no recommendation on booster shots at this time. (Date Updated: 5.26.21)

The duration of protection is currently unknown. (Date Added: 12.15.20)

The Kentucky Department of Health is the distributor all COVID-19 vaccines and requires information from each vaccine recipient including your name, date of birth, race and ethnicity. (Date Added: 12.15.20)

The mRNA COVID-19 vaccines produced by Pfizer and Moderna do not require the use of any fetal cell cultures to manufacture (produce) the vaccine. Early in the development of mRNA vaccine technology, fetal cells were used for “proof of concept” (to demonstrate how a cell could take up mRNA and produce the SARS-CoV-2 spike protein) or to characterize the SARS-CoV-2 spike protein.

The Pfizer and Moderna vaccines were found to be ethically uncontroversial by the pro-life policy organization the Charlotte Lozier Institute. Further, Brian Kane, senior director of ethics for the Catholic Health Association of the United States, stated in an interview for America: The Jesuit Review, “In terms of the moral principles of being concerned about the use of any pharmaceuticals that were developed from aborted fetuses, that is certainly an issue that we all want to be cognizant of and try to avoid their use. With that in mind, the Pfizer and Moderna COVID vaccines that are coming out are not even tainted with that moral problem.” A comprehensive list of COVID-19 vaccines in development and any connection to abortion derived cell lines is available here.
