What do i

does anyone know how to stop this or any tips ?

If the dizziness gets worse you may want to go see a dr or go to the e.r

What I would recommend is to, drink plenty of water and lay down for little. If you have aspirin I would take one before laying down. Make sure your head is a bit elevated. Also, breath steadily, and don't do anything to force your self for about 30 min.

Follow pad instructions, one above the right nipple the other just slightly below the left side of the chest

Immunization is the introduction of a foreign substance to provoke  the immune response system.  immunizations are the same as vaccinations. it introduces foreign (but dead/ weakened) illnesses to train the body to fight against them. specific viruses and bacteria have specific antigens, antigens act sort of like name tags. these name tags the immune system recognize what's dangerous to the body and what's safe.
