Rhesus antibodies, also known as D-antibodies, are injected after birth to prevent a condition known as hemolytic disease of the newborn (HDN). This condition occurs when a mother with Rh-negative blood type is exposed to Rh-positive blood from her baby during pregnancy or childbirth, leading to the mother's immune system producing antibodies against the baby's red blood cells. By injecting Rhesus antibodies after birth, any Rh-positive red blood cells from the baby that may have entered the mother's bloodstream are destroyed before her immune system can mount a significant response, preventing HDN from occurring in subsequent pregnancies. **

This condition occurs when a mother with Rh-negative blood type is exposed to Rh-positive blood from her baby during pregnancy or childbirth. The mother's immune system can develop antibodies against the Rh-positive blood, which can then attack the baby's red blood cells in future pregnancies. By injecting Rhesus antibodies after birth, any Rh-positive blood from the baby that may have entered the mother's bloodstream is targeted and destroyed before her immune system can develop its own antibodies, thus preventing HDN in future pregnancies. **

There are several types of antibodies, but the most commonly known are IgG, IgA, IgM, IgD, and IgE. In the context of blood groups, the most relevant antibodies are the ABO antibodies and the Rh antibodies. ABO antibodies are present in individuals who do not have the A or B antigens on their red blood cells, and they can have anti-A or anti-B antibodies depending on their blood type. Rh antibodies are present in individuals who are Rh-negative and can develop anti-Rh antibodies if exposed to Rh-positive blood. **

IgM antibodies are a type of antibody produced by the immune system in response to an initial infection. They are the first antibodies to be produced in response to a new infection and are typically short-lived. IgM antibodies are important for the body's initial defense against pathogens, but they are eventually replaced by IgG antibodies, which provide long-term immunity. **

Humanized antibodies are produced by taking the variable region genes from a mouse antibody and combining them with the constant region genes from a human antibody. This process creates a chimeric antibody that retains the antigen-binding specificity of the mouse antibody while minimizing the potential for an immune response in humans. The resulting humanized antibody can then be produced using recombinant DNA technology in mammalian cell culture systems. This allows for the large-scale production of humanized antibodies for therapeutic use in treating various diseases, including cancer and autoimmune disorders. **

The savings bank may be blocking online banking customers for security reasons. They may have detected suspicious activity on certain accounts and are taking precautionary measures to protect their customers' funds and personal information. Additionally, the bank may be conducting routine maintenance or updates to their online banking system, temporarily restricting access to ensure a smooth and secure user experience once the maintenance is complete. It is also possible that there may be technical issues or glitches with the online banking platform that need to be resolved before customers can access their accounts again. **

Savings bank transactions can typically be deleted by accessing the account statement or transaction history on the bank's online portal or mobile app. From there, you can select the specific transaction you wish to delete and look for an option to remove or delete it. If you are unable to delete the transaction yourself, you can contact your bank's customer service for assistance in removing the transaction from your account history. It's important to note that some transactions may not be able to be deleted, especially if they are already processed or finalized. **

As an AI language model, I do not have a physical body, so I do not have antibodies. Antibodies are produced by the immune system of living organisms to help fight off infections and diseases. Each person's immune system produces a unique set of antibodies to target specific pathogens. The number of antibodies a person has can vary depending on their individual immune response and exposure to different pathogens. **
