Let’s define some terms.
According to HHS, a vaccine is made from very small amounts of weak or dead germs that can cause diseases: for example, viruses, bacteria, or toxins.
Vaccination is the act of getting a vaccine, usually as a shot. However, vaccines can also be administered sublingually (under the tongue) or a mist up the nose.
Immunization is the process of becoming immune to (protected against) a disease.
Note: even though vaccines are often referred to as “immunizations,” per manufacturers that is not always the case. You can also become immunized through natural exposure to a virus.
Inactivated vaccines:
Live-attenuated vaccines:
Messenger RNA (mRNA) vaccines:
Subunit, recombinant, polysaccharide, and conjugate vaccines:

Viral vector vaccines:
Although not on the market yet, you may hear about DNA vaccines + Recombinant vector vaccines (platform-based vaccines) that are currently being developed.
