An individual may be exposed to a pathogen and become infected without actually getting sick. This is known as a subclinical inf
ection. Even in subclinical infections, the individual's adaptive immune system can generate memory for the pathogen. What type of adaptive immunity is this?
Naturally acquired active immunity occurs when an antigen comes naturally in the body and immune cells are produced against it which also generates memory against the pathogen. It can lead to disease or just cause a primary immune response in which host do not get sick.
Artificially acquired active immunity occurs when antigen is introduced from outside in the form of a vaccine or other substance. It can initiate primary response but do not cause disease.
So naturally acquired active immunity is the type of adaptive immunity which can cause subclinical infection.
I believe the answer should be your doctor. As the pharmacists job is to make the medicine whereas the doctor is more likely to know how to handle symptoms. You should definitely contact your doctor or 911.
