When you have immunity, your body has antibodies against a foreign organisms (i.e. bacteria and virus) .
Usually this is achieved by exposure to these organisms.
That is: 1. you get an infection (or vaccination with inactive parts of a bacteria or virus), 2.your body defeats the invader, 3. some of the cells in your body "remember" which antibodies they produced , 4. next time you are exposed to the same foreign organism, these cells quickly produce antibodies so you won´t get ill (i.e. you are immune)
When you have passive immunity, it usually is due to a vaccination with antibodies. Your body hasn´t produced the antibodies on its own. So once the antibodies become too old and inactive, you are not immune any longer, and when you encounter the foreign organism again, it will be like a novel infection, because it has no memory cells, which can respond quickly.

What is one source of passive immunity?
One source of passive immunity is maternal antibodies transferred to the baby through breastmilk. These antibodies help protect the baby against infections until their own immune system fully develops.
How do you acquire passive immunity?
You can get passive immunity through a placenta when you are a fetus in your mothers womb or you can be injected with antibodies that have most likely been forced to grow due to somebody putting a disease in an animal such as a rabbit. Unfortunately passive immunity does not last very long because the antibodies are detached from their white blood cells which keeps them a live and also stores the antibodies in their memory so you can not become immune forever via passive immunity as it is only passive e.g. short lived/quick
How are different active and passive?
Active immunity is generated by your body. So you get active immunity as a result of infections or due to vaccines. Passive immunity is not generated by your body. Here the antibodies are to be supplied. Child gets the antibodies from mother. Alternately you get the antibodies via injections. The effect of active immunity is long lasting. The effect of passive immunity is short lived. So the active immunity is considered as better. The passive immunity has one advantage. It is available with immediate effect, while it takes about two to three weeks, before the effects of active immunity is available.
Compare passive immunity to active immunity?
Active Immunity - Vaccines are used for health purposes to expose our bodies to a particular antigen. These antigens are usually killed or severely weakened to decrease their potency. After destroying these pathogens, the body stores some T cells as memory cells, due to the fact they code for a particular antigen and can be when needed. This memory in T cells can be a means of artificially acquiring immunity while a genuine attack by a pathogen is a naturally acquired type of immunity. Passive Immunity - This is where immunity to particular antigens as a result of genetic traits passed on from parents rendering the offspring immune to a particular pathogenic threat.
How many long times passive immunoglobulin should use in dogs?
Your grammar is a little oddly worded, but if you are asking how long a puppy would have "passive immunoglobin" (like passive immunity from the mother) then your answer would be up to 6 months after birth.
Passive immunity does not last as long as active immunity?
Passive immunity is temporary and typically lasts for a few weeks to a few months, as it is acquired from an external source such as through the transfer of antibodies from another individual or through vaccination. In contrast, active immunity is longer lasting as it involves the body's immune system producing its own antibodies after exposure to a pathogen.
Can you gain passive immunity against H1N1?
Yes, passive immunity against H1N1 can be acquired through the transfer of maternal antibodies to a newborn or through the administration of preformed antibodies, such as monoclonal antibodies. However, this type of immunity is temporary and does not provide long-lasting protection.
How is active immunity similar to passive immunity?
Both active and passive immunity provide protection against specific pathogens. Active immunity is developed by the body after exposure to a pathogen or through vaccination, while passive immunity is acquired through the transfer of pre-formed antibodies from another source. Both types of immunity are specific to the pathogen encountered or targeted by the antibodies.
Compare and contrast active and passive immunity and give a rea life example?
Active immunity is produced by the body's immune system in response to exposure to a pathogen or vaccine, leading to the production of memory cells for long-term protection. Passive immunity is acquired from an external source such as mother to infant transfer of antibodies or through medical intervention, providing immediate but short-lived protection as it does not generate memory cells. A real-life example is receiving a vaccination (active immunity) to develop immunity to a specific disease compared to receiving pre-formed antibodies through a blood transfusion (passive immunity) for immediate but temporary protection.
What is passive imunity?
Passive immunity is the transfer of ready-made antibodies from one individual to another. This can occur naturally, such as when a baby receives antibodies from its mother through breast milk, or artificially, through the administration of antibodies derived from another individual or animal to provide protection against a specific pathogen. The immunity provided by passive transfer is temporary and does not result in long-lasting protection.
Why does passive immunity usually not last for long?
When you have immunity, your body has antibodies against a foreign organisms (i.e. bacteria and virus) . Usually this is achieved by exposure to these organisms. That is: 1. you get an infection (or vaccination with inactive parts of a bacteria or virus), 2.your body defeats the invader, 3. some of the cells in your body "remember" which antibodies they produced , 4. next time you are exposed to the same foreign organism, these cells quickly produce antibodies so you won´t get ill (i.e. you are immune) When you have passive immunity, it usually is due to a vaccination with antibodies. Your body hasn´t produced the antibodies on its own. So once the antibodies become too old and inactive, you are not immune any longer, and when you encounter the foreign organism again, it will be like a novel infection, because it has no memory cells, which can respond quickly.
How are they different between active immunity and passive immunity different?
Active immunity is acquired when the body produces its own antibodies in response to an infection or vaccination, providing long-lasting protection. Passive immunity is acquired through the transfer of pre-formed antibodies from another source, providing immediate but temporary protection.
