How many doses of the H1N1 Flu nasal spray vaccine are needed?
In adults, only one dose of the H1N1 vaccine, including the H1N1 Flu nasal spray vaccine, is needed for protection. All children 2 through 9 years of age getting a H1N1 vaccine will need two doses of the H1N1 vaccine (either the H1N1 Flu shot or the H1N1 Flu nasal spray vaccine), The first dose should being given as soon as vaccine becomes available. The second dose should be given 28 or more days after the first dose. The first dose “primes” the immune system; the second dose provides immune protection. Children who only get one dose of vaccine when they need two doses may not be fully protected. Be sure to follow up to get your child a second dose if they need one. It usually takes about two weeks after the second dose for protection to begin.
