WASHINGTON--(BUSINESS WIRE)--We are encouraged by reports that are now emerging from various clinical trials of 2009 H1N1 influenza vaccines, conducted by various vaccine manufacturers. We expect additional companies to announce their preliminary trial results shortly. The early data from these trials indicate that 2009 H1N1 influenza vaccines are well tolerated and induce a strong immune response in most healthy adults when administered in a single unadjuvanted 15-microgram dose. We congratulate the companies on these trials, which are an important part of the ongoing worldwide effort to develop vaccines to protect the public from 2009 H1N1 influenza.
