The CDC has these definitions:

Johns Hopkins uses the same definition.

Until COVID was a thing and people were popping off hot takes on why they don’t need the ‘evil 5g nanobot experimental vaccine’ I’ve never heard or used the term natural immunity in that way.

This is a medical dictionary definition:

Types of Immunity. An individual may be naturally immune to certain pathological conditions or may acquire immunity through either active or passive means.
Natural immunity is a genetic characteristic of an individual and is due to the particular species and race to which one belongs, to one’s sex, and to one’s individual ability to produce immune bodies. All humans are immune to certain diseases that affect animals of the lower species; males are more resistant to some disorders than are females, and vice versa. Persons of one race are more susceptible to some diseases than those of another race that has had exposure to the infectious agents through successive generations. One’s individual ability to produce immune bodies, and thereby ward off pathogens, is influenced by one’s state of physical health, one’s nutritional status, and one’s emotional response to stress.

In order for an individual to acquire immunity one’s body must be stimulated to produce its own immune response components (active immunity) or these substances must be produced by other persons or animals and then passed on to the person (passive immunity). Active immunity can be established in two ways: by having the disease or by receiving modified pathogens and toxins. When an individual is exposed to a disease and the pathogenic organisms enter the body, the production of antibody is initiated. After recovery from the illness, memory cells remain in the body and stand ready as a defense against future invasion. It is possible, through the use of vaccines, bacterins, and modified toxins (toxoids), to stimulate the production of specific antibodies without having an attack of the disease. These are artificial means by which an individual can acquire active immunity.

Merriam Webster:

Medical Definition of innate immunity
: immunity possessed by a group (as a species or race) that is present in an individual at birth prior to exposure to a pathogen or antigen and that includes components (as intact skin, salivary enzymes, neutrophils, natural killer cells, and complement) which provide an initial response against infection
— called also natural immunity

Medical Definition of acquired immunity
: immunity that develops after exposure to a suitable agent (as by an attack of a disease or by injection of antigens)
