At the follicular dendritic cell surface, B cells (centrocytes) with low affinity receptors (Fab sites) for antigen: exhibit diminishing contribution to secondary antibody responses. exert a dominant contribution to subsequent responses to the specific antigen. die by apoptosis. respond to different antigenic epitopes. recycle to become mature virgin B cells. The major serum antibody isotype produced in response to primary immunization with a protein containing that peptide is: IgA IgG IgM IgD IgE Antibodies do NOT: neutralize virus attachment to susceptible host cells opsonize encapsulated Gram-positive bacteria lyse Gram-negative enteric bacilli initiate heavy chain gene rearrangement in stem cells neutralize tetanus exotoxin

Inoculated attenuated Sabin vaccination Salk Inactivated multiply three revert two prophylaxis infantile paralysis myasthenia gravis Poliomyelitis. In contrast, oral polio vaccine (OPV), developed by _______ in the 1960s, contains an _______ virus and can be easily administered by mouth making it useful still in polio eradication programs in developing countries today. OPV poses many risks, however, such as the attenuated virus can _______ in vaccinated people and spread to others or it can _______ to a neurovirulent strain causing disease, making this vaccine virtually unusable in the U.S. today. In the past, this disease often affected small children and was called _______. _______ poliovirus vaccine was developed by _______ in 1954 and is now the form used for all U.S. childhood vaccinations due to its low risk to individuals being vaccinated. _______ is an acute enteroviral infection of the spinal cord that causes neuromuscular paralysis. Because of this, _______ is a mainstay of polio prevention today, and is started in infants at about 2 months of age. There are _______ forms of vaccine utilized today to confer protection against polio.
