ATLANTA (AP) — It will likely be Thanksgiving before many Americans who get the swine flu vaccine are protected, health officials said Monday. Roughly 50 million doses of vaccine are expected to be available by mid-October. But for those who get initial doses right away, that will only mark the beginning of a vaccination process that will take five or more weeks because most people will need two shots, spaced three weeks apart, and it will take a week or two after the second dose before immunity kicks in.- – – -Contact The Daily Reveille’s news staff at [email protected]
