<unk>  vaccines are available either as: * a trivalent or quadrivalent intramuscular injection <unk> 3,<unk> 4, or RIV4, that is, TIV or QIV), which contains the inactivated form of the virus * a nasal spray of<unk> e attenuated<unk>  (LAIV, Q/LAIV), which contains the<unk> e but attenuated (weakened) form of the virus. TIV or QIV induce protection after injection (typically intramuscular, though subcutaneous and intradermal routes can also be protective) based on an immune response to the antigens present on the inactivated virus, while cold-adapted LAIV works by establishing infection in the nasal passages.
