Viruses that typically confer long-lasting or lifelong immunity after infection include measles, mumps, rubella, chickenpox, and most strains of the influenza virus. However, some viruses, like the common cold or norovirus, can infect a person multiple times due to the presence of different strains or lack of long-lasting immunity.
Hepatitis C is an infectious disease that does not confer immunity after exposure. People who have been infected with hepatitis C can get re-infected with the virus.
Naturally acquired active immunity
Active immunity.
rubella,mumps,pertusis.DHF(Dengue haemorragic fever)
They either are vaccinated against those diseases, or they have them and build a natural immunity.
There are different types of immunity Non-specific and Speicific and the best is Innate which is inborn, acquired active after exposure to a disease like measles & mumps and by vaccination which is Artificially acquired active immunity which is the practice now to prevent from incurring a disease.

Artificially acquired Active- vaccines (active or live viruses that are lifelong immunity) Artificially acquired Passive - gamma globulin injection that is temporary (used for overseas trips)
False, because not all vaccines provide lifelong immunity. Some require boosters or reimmunization.
No, hemophilia does not confer an advantage against malaria. People with sickle-cell anemia do have an immunity, of sorts.
Pooled human serum globulin is antibodies (or antitoxins) found in our blood. When administered to a patient after exposure to Hepatitis A it is a type of Artificially acquired passive immunity.
In order to show positive immunity your blood level must reach a level of 1.10 If it's 90 then you have no immunity and should be vaccinated. If you are between say 1.00 to 1.09 then you some immunity but should have a booster of either measles (mmr) or varicella.
