Quite simply put. The vaccine is actually an inactive virus which basically gives your body a road map in which to fight off the attacking virus.
After the infection, you get naturally acquired active immunity to the chickenpox. You have a very low chance of getting chickenpox again because your immune system has made antibodies to fight off.
ADAPTIVE immunity. Your body sees the pathogen, so it can be ready if it ever encounters it again.
no it is not
Natural immunity to chickenpox results from previous infection. There is no other way to be naturally immune to chickenpox. Sometimes, the previous infection may be mild enough that the disease was not noticed. You can become artificially immune to chickenpox by getting chickenpox vaccine.
Yes. There is a rabies vaccine.
how using a vaccine may give long term immunity to malaria
Artificial active immunity. Artificial because it is due to vaccination. Active because the body is stimulated by the vaccine to produce antibodies against Hepatitis B virus antigen.

Immunity to what ever you wish to vaccinate
Natural immunity occurs through contact with a disease. There are two types of natural immunity. Actively acquired and passively acquired. Actively acquired - When the body has already experience an infection by that pathogen Passively acquired - Antibodies pass across placenta providing a newborn baby with immunity against disease. Antibodies are also present in breatsmilk. Artificial immunity develops through delibereate action such as vaccine. There are two types: Actively acquired and passively acquired Actively acquired - This is by vaccination at a suitable time in the person's life, not when they are infected. eg TB vaccine Passively acquired - The vaccine contains ready-made antibodies which provide immediate relief by destroying the antigens. This is given when the person has been infected with the antigen and has no preivous immunity eg tetanus
Tetanus shots protect against diphtheria, tetanus, and pertussis.
Pneumococcal polysaccharide disease is caused by a bacteria. It can be deadly but a vaccine was developed to head off the disease before it starts. The vaccine works when a small amount of the bacteria is injected into the patient and his or her immunity works against the disease, causing immunity.
