Bill Cullen was partially crippled by polio as a child. He still holds the record for hosting more game shows than any host in history at 24.
By giving you a watered down version of the disease, white blood cells in your immune system learn which antibody to produce and how to fight polio. If you get the disease for real, they can make it much quicker, and therefore get rid of it before you even show symptoms.
I dont know if you can still be born with Polio, but I do know that my grandfather was born with it but did not show signs of having polio until he began to try and crawl.
Yes.
The person will show antibodies in a blood test.
There are many reasons why a person has to have a blood test done. Mega T Green Tea will show up in a blood test, and can alter the results.
Less immunity in blood
Yes, there is a website called "Blood Group Calculator" which will show you all types of various blood groups and calculates the child's blood group based on their parents.
Polio hasn't been completely eradicated. It is no longer in North America. However, parts of Afghanistan, Pakistan, and Nigeria are believed to still show signs of Polio. This disease can be eradicated though. To eradicate a disease, you must first stop the transmission of the virus. This means that immunizations must be given. This should mainly start with children before they are susceptible to the virus. Eventually the virus will die because it will not be allowed to transmit to another person.

Yes, if both the father and mother have the genotype of AO, then they would both show up as phenotype A and they could have a child with type O blood. As O is recessive, the type A would be dominant and therefore show up as the blood type. The mother could contribute the positive Rh factor leading to type O+ in the child.
It depends- each person has two alleles, and the combination determines what blood type they are. (Possibilities are A, B, and O.) Each parent contributes one allele (one of their pair, at random) to the child. But there are several factors that determine a child's blood type. A and B are 'dominant', meaning that if the parent gives a child and A or a B allele, then that is what the child's blood type is, regardless of if the other allele the child has is an O. But if one parent gives an A and the other a B, then the child is AB, since A and B are as equally dominant. But if both parents give the child an O, then the child will be an O. But it is possible to have an O child if neither parent is O, because O is 'recessive', or won't show up if there's a dominant allele. For example: Say the mother's alleles are A,O. She would be a type A. And if the father was the same... The baby could have 3 possible allele combinations (AA, AO, or OO). Either of the first two combinations would mean that the child was an A, but it would also be possible for the child to be an O, although less likely (33% chance). So to answer your question, it's not a matter of receiving a blood type from one parent, but the child's blood type is the result of both parent's blood types.
