    Depends what you mean by types.

    Defined by what the vaccine contains:

    Live attenuated vaccines - contains an avirulent (nonpathogenic) version of the pathogen you're trying to protect against. Can be obtained for example by serial passage through animal cells. e.g Oral Polio Vaccine.

    Live heterologous vaccines - contains a closely related organism to the pathogen, antibodies raised against this relatively non-pathogenic organism cross react with antigens on the target pathogen. e.g smallpox vaccination using cowpox.

    Inactivated vaccines - contains heat or chemical (often formaldehyde) killed infectious agents, unable to cause disease but still posessing antigens to stimulate antibody production. e.g injected polio vaccine.

    Subunit vaccines - contain specific elements of the pathogen (for example a viral coat protein) sufficient to raise an antibody response. e.g Hepatitis B vaccine.

    Toxoid vaccines - contain inactivated (usually by heat) toxins that no longer cause damage but are still immunogenic. e.g Tetanus vaccine.

    If you were looking for a list of the types of diseases we can prevent by vaccine, this is extensive if including both human and animal vaccinations. Vaccine preventable human diseases are as follows:

    Anthrax, Cervical Cancer, Diptheria, Hepatitis A, Hepatitis B, Haemophilus Influenzae type b, Human papillomavirus, Influenza, Japanese encephalitis, Lyme Disease, Measles, Meningococcus, Monkeypox, Mumps, Pertussis (Whooping Cough), Pneumococcus, Poliomyelitis, Rabies, Rotavirus, Rubella, Shingles, Smallpox, Tetanus, Tuberculosis, Typhoid Fever, Chickenpox and Yellow Fever.
