Swine Flu Vaccination :Trials ?
2009 July 22
Only after the trials are done, which is estimated to take about two months, can health officials recommend a vaccination program. It would be voluntary and would have to be rolled out in stages because not nearly enough doses for all Americans will be ready in the fall even if there are no testing or production problems.
For the trial, healthy adult volunteers will be recruited at eight sites and given one or two shots, each containing 15 or 30 micrograms of vaccines made by two different companies. Some will get the injections concurrently with seasonal flu vaccines.
