Is the Swine Flu vaccine a spray?

Answer 1

There are H1N1/09 flu vaccines for three different administrative routes now. The three formulations of vaccine are for intranasal, intramuscular and now also intradermal administration. The intranasal spray is misted into the nose, the intramuscular injection is the well-known "flu shot"/"flu jab", and the intradermal is provided with its own micro-injection system using a tiny needle to inject the vaccine just under the layers of the skin. The flu vaccines for injection are made with an inactivated H1N1 virus, meaning that the virus has been altered in such a way that it cannot reproduce in the body and cause infection (it is "dead"). In contrast, the intranasal mist is made with an attenuated or weakened virus which provides the same immunity with a less invasive administration. LAIV (live attenuated influenza vaccine) does not have to be injected to create the immunity like the inactivated vaccines. But as a weakened virus, it is also incapable of causing influenza illness.

Children 10 years old and under need two vaccinations, regardless of the type of vaccine, to provide them with the immunity since they have immature immune systems. One initial vaccination followed in about a month by a second vaccination "booster", will, in about 2 or 3 weeks after that, have caused their immune systems to produce enough antibodies to give them full immunity.
