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.)
Pneumovax is typically given as a single injection, but a second dose may be recommended in some cases. This vaccine is generally recommended for adults over the age of 65. Prevnar 13 is the pneumonia vaccine most often recommended for children; with these products, dosing guidelines call for up to four injections. The ideal vaccination schedule for Prevnar 13 is as follows: 1  First dose -- 2 months old.  Second dose -- 4 months old.
