Key Differences
Inoculation is a broad term referring to the introduction of an agent into the body to prevent disease. This agent could be a live pathogen, a weakened form of the pathogen, or something else entirely that stimulates the body's immune response. Vaccination, however, is a subset of inoculation that specifically involves administering a vaccine. A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease.
Inoculation can be traced back to practices like variolation, where material from smallpox sores was introduced into healthy individuals to induce a mild form of the disease and confer immunity. Vaccination, on the other hand, began with Edward Jenner's use of cowpox material to immunize against smallpox, marking the start of vaccines as we understand them today. Therefore, all vaccinations are forms of inoculation, but not all inoculations are vaccinations.
The purpose of inoculation is to stimulate the body's immune system to recognize and fight specific pathogens without causing the full-blown disease. This can involve various methods and materials. Vaccination achieves this goal through the use of vaccines, which are scientifically developed to contain harmless components of pathogens (like proteins or sugars), weakened or dead pathogens, or a blueprint for producing pathogen components, like in the case of mRNA vaccines.
In terms of application, inoculation covers a wider range of techniques beyond infectious disease prevention, including allergy treatments and cancer immunotherapy. Vaccination specifically targets infectious diseases by introducing a vaccine into the body, usually through injection, to prompt an immune response that will protect against future infections by that pathogen.
The terminology difference also highlights the evolution of medical understanding and practices. Inoculation refers to an older, broader concept of disease prevention, while vaccination is a more modern term, reflecting advancements in medical science and the development of safe, effective vaccines against a wide array of diseases.

Some cancer treatments involve inoculating the patient with modified cells.
Vaccinate
Specifically involves a biological preparation.
The vaccine contains attenuated viruses to safely stimulate immunity.
Inoculate
Can apply to various medical treatments.
The doctor inoculated the patient against allergies with a specific antigen.
Vaccinate
Administration of a vaccine to induce immunity.

Inoculate
Treat with a vaccine to produce immunity against a disease; vaccinate
He inoculated his tenants against smallpox
Vaccinate
To inoculate with a vaccine in order to produce immunity to an infectious disease, such as diphtheria or typhus.
Inoculate
To introduce a serum, vaccine, or antigenic substance into (the body of a person or animal), especially to produce or boost immunity to a specific disease.
Vaccinate

Vaccinate
To inoculate with the cowpox by means of a virus, called vaccine, taken either directly or indirectly from cows; now, generally, to administer (by injection or otherwise) any vaccine with the objective of rendering the recipient immune to an infectious disease. One who has been thus immunized by vaccination is said to be vaccinated against a particular disease. One may be thus immunized (vaccinated) also by oral ingestion or inhalation of a vaccine.

Common Curiosities
What does vaccinate mean?
Vaccinate means to administer a vaccine to a person to induce immunity against a specific infectious disease.
Are inoculate and vaccinate interchangeable?
While related, they're not completely interchangeable. Vaccinate is a specific type of inoculation using vaccines.
Can you be inoculated without a vaccine?
Yes, inoculation can involve other agents besides vaccines, such as in the case of allergy treatments or variolation.
Can animals be vaccinated?
Yes, animals can be vaccinated to protect them against various diseases, similar to human vaccination practices.
What's a recent advancement in vaccination?
Recent advancements include mRNA vaccines, which teach our cells how to make a protein that triggers an immune response.
Why is vaccination important?
Vaccination is crucial for preventing infectious diseases, protecting individuals and communities, and eradicating diseases.
What does it mean to inoculate someone?
To inoculate someone means to introduce an agent into their body to stimulate immunity against a disease, using various methods.
