prior to the development of the vaccine for this disease, there was an epidemic in 1952 in the united states which left over 21,000 people with permanent paralysis.
measles
meningitis
influenza
polio

Explanation:

• ELISA (Enzyme - Linked Immunosorbent Assay): It is a biochemical technique used to detect the presence of antigens or antibodies in a sample. Antigens can be proteins, peptides, or other molecules, and antibodies are proteins produced by the immune system in response to antigens. In an ELISA, specific antibodies or antigens are immobilized on a surface (usually a micro - titer plate), and then the sample (containing the target antigen or antibody) is added. A series of enzyme - labeled secondary antibodies or detection molecules are then used to visualize the binding, which indicates the presence of the target molecule.
• Polio: Before the polio vaccine was developed (the Salk vaccine in 1955 and the Sabin vaccine later), the 1952 polio epidemic in the United States was one of the worst in history. It caused widespread paralysis. Measles is a viral disease that can cause a rash, fever, etc., but its major complications are more related to respiratory and other infections rather than large - scale permanent paralysis in the pre - vaccine era. Meningitis (inflammation of the meninges) can be caused by various pathogens (bacteria, viruses, fungi) and has symptoms like headache, neck stiffness, etc. Influenza (flu) is a respiratory illness with symptoms such as fever, cough, body aches.

Answer:

• First question: ELISA
