| Vaccination, on the other hand, imparts passive immunity that is short lived. |
|
| While present, passive immunity may interfere with the immune response to a vaccine. |
|
| Much more commonly, anti-tetanus serum has been widely used to confer passive immunity after potentially contaminated minor injuries. |

| It provides passive immunity and must by given by intramuscular injection once a month during RSV season. |
|
| New approaches to effectively vaccinate newborns so they produce their own immune responses when passive immunity wanes are highly sought. |
|
| Given the age of the calves, it is also possible that passive immunity played a role in immune response. |

|
| Colostrum provides the calf with passive immunity and important nutrients. |
|
| Perhaps most importantly, it conveys passive immunity to the calf before its immune system is fully developed. |

|
| Other studies are also needed to identify which immune mechanisms are involved and to better understand the role of maternal passive immunity in these infants. |
|
| Newborn calves acquire passive immunity by ingestion and absorption of antibodies present in colostrum. |
|
