Researchers can design antibodies that specifically target a certain antigen, such as one found on cancer cells. Sometimes the antibodies are produced by the body itself when they find themselves being invaded by antigens. Instead of waiting for days or even weeks for a patients immune system to start producing antibodies, mAbs ensure an instant response against a disease!

The clones cells are of two types, plasma cells, and memory B cells. Your antibodies can develop in as few as a couple of days or it could potentially take weeks. The number and type of antibodies varied between people. The antibodies attach to a specific protein on the virus, helping prevent replication of the virus and allowing your own immune system to clear the virus more quickly than you'd be able to on your own.

Even though the vaccine is weak, it still helps the body stimulate its immunity as a response to the presence of antigen. The vaccine trains a healthy immune system to protect from a future infection, and the protection can last much longer..
