•Diphtheria — Secondary transmission is impossible, as it does not contain the bacillus Corynebacterium diphtheriae, but an inactivated toxin (toxoid) produced by the bacillus. http://www.immunize.org/catg.d/p4203.pdf
•Hepatitis B — Secondary transmission of the vaccine virus is not possible: vaccine virus is neither live nor whole.
And a live attenuated vaccine administered by nasal spray. There has been one recorded case of secondary transmission of the live attenuated vaccine. http://www.cdc.gov/vaccines/pubs/pinkbook/flu.html
•Pertussis — Secondary transmission of the disease is impossible, because it is an acellular vaccine, containing only fragments of the pertussis organism, and is therefore incapable of replicating. http://www.immunize.org/catg.d/p4212.pdf
•Polio — The inactivated (killed) poliovirus vaccine, covering all 3 serotypes, is used. Secondary transmission is impossible as the vaccines do not contain a live virus .
•Rotavirus — Vaccine-strain virus has been found in stool of vaccinated infants, but transmission has never been documented.
•Rubella — The US vaccine uses the live, attenuated RA 27/3 rubella strain. Secondary transmission of the vaccine virus has never been documented; there is a possibility that the vaccine virus can be passed through breast milk.
•Tetanus — Secondary transmission from the vaccine is impossible, as it does not contain the bacillus Clostridium tetani, but an inactivated toxin (toxoid) produced by the bacillus.
•Varicella — For the pediatric vaccine formulation, the live, attenuated Oka strain is used. Data suggest that transmission of varicella vaccine virus is a rare event.
According to the CDC, there are only 5 cases (out of, over 55 million doses administered) of infection caused by the vaccine shedding. The varicella vaccine virus may shed if a person develops vesicular rash, post vaccination.
