Physics covers a wide range of phenomena, from elementary particles (such as quarks, neutrinos, and electrons) to the largest superclusters of galaxies. Included in these phenomena are the most basic objects composing all other things. Therefore, physics is sometimes called the  fundamental science .
Two types of influenza vaccines are available: 1  TIV (flu shot (injection) of trivalent (three strains; usually A/H1N1, A/H3N2, and B) inactivated (killed) vaccine) or. 2  LAIV (nasal spray (mist) of live attenuated influenza vaccine.)
About six months are required to produce influenza vaccine each year. How is the vaccine given? The inactivated vaccine is generally given as an in-tramuscular injection; one inactivated vaccine can be given as an intradermal injection with a micro needle into the skin of the arm for persons ages 18 through 64 years.
