HELLO MACHII ✋....



--->The vaccine that protects against the bacteria Hib, which causes meningitis, is a good example.

In other cases, such as the DTaP vaccine, which protects against diphtheria, tetanus, and pertussis, the initial series of four shots that children receive as part of their infant immunizations helps them build immunity.
