When charged particles from the sun strike atoms in Earth's atmosphere, they cause<span>electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful </span>aurora<span>, or northern lights</span>
The vaccinations triggers the active immunity in the organisms. The active immunity can be defined as the immunity when the immune system of the organism works to produce antibodies against the encountered antigen. Through the vaccination, the organism is given weakened antigens, which triggers the immune system to secrete antibody against it. This encounter to the antigen and release of the antibodies provides lifelong immunization to that particular antigen. After the vaccination is given, it takes almost two weeks for the animal to produce immunity against it.
