From what I’ve read the vaccine can cause a positive antibody test…which is good because that means you had an immune response from the vaccination. But the antigen and PCR…no. At least according to these sources…
Dr. Matthew Binnicker, an expert in the diagnosis of infectious disease, explains the benefits and limitations of diagnostic testing as more people receive Covid-19 vaccinations.

“The two Covid-19
vaccines (Pfizer/BioNTech and Moderna) currently authorized for use in the United States are mRNA-based vaccines. They do not consist of the entire genome of the SARS-CoV-2 virus, which causes Covid-19. Instead, these vaccines are made of a small region of the viral genome, which enters the host cell and “tricks” the cell into making a specific viral protein (i.e., the Spike protein) against which an immune response is generated. RNA molecules are inherently unstable, being targeted by enzymes that can degrade the RNA within hours. Therefore, mRNA-based vaccines will not cause a Covid-19 PCR test to be positive.,
these vaccines will not cause rapid antigen tests to be positive, since the proteins produced following vaccination are not expressed in the respiratory (i.e., nasal) tract, which is sampled for Covid-19 PCR or antigen testing.”
If I get the vaccination, will I become a false positive for the COVID-19 testing (e.g., PCR test, antigen test or antibody test)?

Question
If I get the vaccination, will I become a false positive for the COVID-19 testing (e.g., PCR test, antigen test or antibody test)?
Receiving the COVID-19 vaccine will not affect the PCR or antigen test results since these tests check for active disease, not immunity. There is no virus present in the mRNA COVID-19 vaccine.
The vaccine is intended to induce an immune response, so the serology test (antibody test) may be positive in someone who has been vaccinated.
None of the COVID-19 vaccines currently in use in the U.S. use the live virus that causes COVID-19. The goal of vaccination is to teach our immune systems

Will the COVID-19 vaccine cause me to test positive?
No, the vaccine won’t cause you to test positive on a COVID-19 viral test, such as the PCR or antigen tests. However, you may test positive for the antibody test, due to developing an immune response.
So we need to differentiate between antibody test, antigen test, and PCR. The NCAA requires the use of PCR/NAAT test. This test will not show false positives after the vaccine. Even if the NCAA required an antibody test, a positive reading would be an actual good thing.
