- which type of antibody is produced first and in greater amounts upon subsequent exposures to an antigen (weeks, months, years, or decades after the initial exposure)?

Respuesta :

The correct option is B ;  IgG type of antibody is produced first and in greater amounts upon subsequent exposures to an antigen (weeks, months, years, or decades after the initial exposure)

IgG, or immunoglobulin G, is the most prevalent type of antibody. It defends against viral and bacterial infections and is found in blood and other bodily fluids. After an infection or vaccination, IgG can take some time to develop.

IgM and IgG antibodies to SARS-CoV-2 may both be found shortly after infection. IgG is typically detectable for extended periods of time, but IgM is most effective for diagnosing recent infection and typically becomes undetectable weeks to months after infection.

For instance, IgA is abundant in the mucous membranes, but IgG, the most prevalent antibody, is primarily present in blood and tissue fluids. … antibodies fall into five categories: IgG, IgM, IgA, IgD, and IgE.
