Seeing alot of people confused about #NaturalImmunity vs #vaccineinducedimmunity vs #passiveimmunity with regard to #covid19.
Hope this helps clear it up (some good explanation here)

Alot of it has been "we have a natural immunity to covid 19." This is only true, as per above, if we have been infected with it. We don't have a natural immunity without exposure, just the ability to develop it. And not all immunity is total.
Someone referring to the acute phase response (i.e the initial non-specific response, fever etc) is referring to part of the immune response, but the term "natural immunity" refers to this priming process as explained above. In covid 19,acute phase response is not enough for many
Hence the need for vaccines, especially in those who are already at a higher risk due to other illnesses, age, or a less functional immune system.
