A vaccine is substance used to stimulate a person’s immunity (protection against) a certain disease.

Some vaccines stimulate immunity by encouraging the body to make antibodies (humoral immunity).

VACCINE

Liveattentuanted

•Form of the wild virus or bacterium •Can replicate themselves so the immune response almost similar to natural infection

Inactivated•Cannot replicate and thus generally not as effective as live vaccines•Immune response mostly antibody based

Breasts produce colostrum beginning during pregnancy and continuing through

the early days of breastfeeding.

This special milk is yellow to orange in color and thick and sticky. It is low in fat, and high in carbohydrates, protein, and

antibodies to keep the baby healthy.

What Is Colustrum ?

Colostrum actually works as a natural and 100% safe vaccine.

It contains large quantities of an antibody called secretory immunoglobulin A (IgA) which is a new substance to the newborn.

Before the baby was born, he received the benefit of another antibody, called IgG, through placenta
