No. Water vapor occurs naturally and is harmless, and is needed for precipitation.
*********************
It could be argued both ways. Water vapour is considered a pollutant by people because of its apparent 90% contribution to the natural greenhouse effect. Though this may be the case, water vapour is, well, simply that: water vapour. It is what turns into rain, and rain is good. So both ways, rain could be considered a pollutant or not.
Sulfur dioxide combining with water vapor in the air produces sulfuric acid, a highly acidic and harmful pollutant that contributes to acid rain.
Water vapor in air condenses into liquid water at the dew point temperature.
Water vapor
drier couse when we have vapor air is wet and when we lost it makes air drier.
When water boils, it turns into water vapor or steam. This water vapor rises into the air and eventually dissipates.

Water vapor, CFCs.
Water vapor in the air is water in the form of a gas.
water vapor, oxidized
Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.
Pollutant
When water vapor is added to the air, the density of the air decreases. This is because water vapor molecules are less dense than dry air molecules.
The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Water vapor is water is gas form. Humdity is the amount of water the air can hold. So, they're both water in the air.
Relative humidity is a measure of the amount of water vapor in the air. It represents the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature, expressed as a percentage.
It takes a lot of energy to turn water into water vapor. The amount of energy that the water gains to turn into water vapor begins to be transferred into the surrounding air. If the air is willing to take on more energy the water vapor condenses quicker. This is why hot air will hold more water vapor than cold air.
Saturated air is more dense.
