How far between can children get the seasonal and H1N1 injections?
Keep in mind that there are two types of vaccines, both for seasonal influenza and for the novel H1N1 pandemic virus. That is the inactivated (injection) and the live (nasal spray). For the inactivated vaccines (injections), they can be given at the same time at different sites. For the live attenuated seasonal and H1N1 influenza vaccines (nasal sprays), we do not have data at this time to support both being administered at the same time. And so for now, they should be administered about four weeks apart. For children receiving the inactivated seasonal influenza vaccine (injection), they should be able to receive the live H1N1 pandemic vaccine (nasal spray) at the same time and not have to worry about interference.
