Describe What is meant by natural immunity and how it may be acquired actively or passively?
Natural immunity is the immunity that the body develops after being exposed to a pathogen, either through infection or vaccination. Active immunity is acquired when the body's immune system produces its own antibodies in response to exposure to a pathogen. Passive immunity, on the other hand, is acquired when pre-formed antibodies are introduced into the body, either naturally (e.g. from mother to fetus during pregnancy) or artificially (e.g. through injections of antibodies).
As an infant receives her first dose of oral polio vaccine the nurse explains to her parents that the vaccine is a preparation of weakened virus What type of immunity will the infant develop?
The infant will develop artificially acquired active immunity
If your grandparent got vaccination for a disease why didnt their offspring get vaccination for that disease?
Those are things that are not passed from your parents or grandparents to you. Only if you had a gene that prevented you from getting a disease would that work. People don't usually get dog or cat or cattle diseases because they have an innate immunity to some of them.
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.
What is natural immunity?
Natural immunity describes the state of being able to resist illnesses; such a condition originates in a healthy immune system. Natural immunity is resistance that one inherits from one's parents, in contrast to acquired immunity, which one develops over the course of one's life. Acquired immunity is built up when one suffers from and beats a given illness; memory cells in the immune system essentially learn the illness and remember how to beat it in the future. If an individual were not born with some form of inherited immunity, it is unlikely that he would survive his infancy as there are many common illnesses that would be deadly to those without proper immunity. One of the major properties of a healthy and effective immune system is the ability to differentiate between self and non-self. Natural immunity confers that ability upon an infant to some degree, allowing his immune system to identify and fight threats. If one's immune system were unable to make the distinction between self and non-self, it would likely attack various necessary aspects of the body rather than harmful and antagonistic elements. Natural immunity ensures this is not a problem in healthy infants; their immune systems are already capable of distinguishing self from non-self, of identifying threats, and of fighting a number of common ailments.
How can you write the word vaccination in a sentence?
1) The school sent a letter to all parents explaining the need for proof of the child's vaccination record. 2) Martha took her son to the doctor today for a measles vaccination.
Passive immunity does not last as long as active immunity?
Active Immunity is subdivided into two.First, the Natural Active Immunity which last a lifetime because our memory T-cells recognized the pathogen in our first exposure thus it was able to make anti-bodies againts it.Second,the Artificial Active Immunity which is commonly introduced to us by meas of vaccine.Examples of these are BCG,DPT,Hepatitis Vaccine,Tetanus Toxoid and OPV,these vaccine may contain LAM(Live Attenuated Microorganism) or dead microorganism that are being introduced to our body artificially that leads to activation of memory T-cells to also form anti-bodies, on the other hand it does not protect us for a lifetime.Serum Levels must be obtained and a booster shot is suggested in Hepatitis Vaccine after four years from the last dose recieved.
Who should pay for mandatory vaccination for children?

Why should parents give polio drops to their childrens?

What is parental immunity?
Allow me to explain a complicated law in simple terms: parental immunity bars a child less than 18 years old from suing the parents for negligence or intentional torts.
What is inborn immunity?
Inborn immunity is either a genetic quirk , or something you inherit from your Mother, especially if you are breast-fed as a baby. Awoman can pass anti-bodies to the baby from things she herself has been exposed to.
What happened at the first vaccination?
It was an improvised small pox vaccine which his inventor (I forgot his name, it was in the 18th century) tried on a 5-year-old, who was a servant's son (without warning his parents, of course). He used a virus taken from the bovine (cow) version of the disease, which was less virulent while offering immunity against the deadly human disease.
