Question

which type of antibody is the first one made by a newborn and also generally the first one to combat an infection?
a igg
b igm
c ige
d igd

Explanation:

IgM is the first antibody produced by the neonatal B - cells in response to an antigen. It is also the first antibody to be secreted by B cells during an initial immune response. IgG is the most abundant antibody in the blood but is not the first - made antibody by a newborn. IgE is involved in allergic reactions and parasitic infections. IgD has a less - defined role in the immune response compared to IgM in terms of being the first - made antibody in a newborn and first to combat infection.

B. IgM
