What is the nasal spray flu vaccine? There are two types of flu vaccine: the flu shot and the nasal spray vaccine. Both types of vaccine are being made against 2009 H1N1. The nasal spray flu vaccine (sometimes called LAIV for Live Attenuated Influenza Vaccine) is a vaccine made with live, weakened viruses that cannot grow at normal body temperature and is given via a nasal sprayer. This vaccine was approved for seasonal influenza viruses in 2003 and tens of millions of doses of the vaccine have been given in the United States.
