Zinc boosts the immune system. However, copper must be taken with zinc as zinc displaces copper (an essential mineral for the body).

Not mentioned as doctors should know how to instruct patients to take all three:

Zinc, Hydroxychloroquine, and Z-Pak anti-biotic.

Z-Pak is used to treat pneumonia (bacterial infection) that can occur with COVID-19.

Doctors must warn patients about zinc displacing copper...

If people take 'megadoses of things', there can be side effects.

Zinc can displace copper and cause copper deficiency if there is Zinc Toxicity...

Recommended Intake and sources
The RDA for copper is 900 mcg for adults. Good sources include organ metats (liver), seafood, green leafy vegetable, legumes, whole grains, dried fruits, and water, if it flows through copper pipes.
Deficiency
Copper deficiency causes bone demineralization and anemia; this form of anemia can also be causd by ZINC TOXICITY REDUCING body levels of copper.
