Does the 2nd shot need to be same make as the 1st?

[Anonymous]

My daughter got the 1st shot in Alexandria. Do I need to make sure the 2nd shot is from the same manufacturer (Sanofi)? Anywhere I can find out online?

I don't think manufacturer matters but having done some reading I would personally want to ensure the second dose was still injectible rather than spray.

The flu.gov answer seems to recommend using the same type of vaccine for seasonal flu. I would imagine it may be the same for H1N1. I wish they had said "seasonal and H1N1" to eliminate any doubt.

I guess they may not know themselves as this is so new.
