Compare natural, acquired, and passive acquired immunity, and provide an example of each

Natural immunity: a person develops antibodies after getting the disease. Example is having the measles, then being immune to it.

Acquired immunity: a person develops antibodies after exposure to a pathogen. Example is getting a vaccine

Passive acquired immunity: a person is given antibodies to a disease instead of their body making the antibodies. An example is a newborn who got mom’s antibodies through the placenta.

You should check out the situation and then ask questions like “are you choking”? and if they are able to respond they should nod and if they are not making sound do the heimlich maneuver. i hope this .
