Vaccines cause an immune response but do not cause an actual disease. This immune
response produces cells that can help fight the disease if the body is exposed to it in the
future. What kinds of cells are produced from this immune response that can help with an
infection later?

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
