Question

Why it is difficult to develop vaccines for some diseases?

Open in App
Solution

Certain infectious agents such as viruses have a relatively simple structure, but they are able to undergo rapid modifications. These modifications allow these infectious agents to easily evade the immune system and most of the vaccines fail to work against these viruses. Thus, certain infections cannot be effectively treated by vaccination.
