During week 40 (October 4-10, 2009), influenza activity increased in the U.S.
The first 3.4 million doses of swine flu vaccine -- all the nasal spray vaccine -- will ship in early October, the CDC said today.
In addition, some flu shots may be ready to ship by then, too, Jay Butler, MD, chief of the CDC's H1N1 Vaccine Task Force, said at a news conference.
One in three teenage girls have rolled up their sleeves for a vaccine against cervical cancer, but vaccination rates vary dramatically between states, according to a federal report released Thursday.
The highest rates were in Rhode Island, New Hampshire and Massachusetts, where more than half of girls ages 13 through 17 got at least one dose of the three-shot vaccination. The lowest rates were in Mississippi, Georgia and South Carolina, where fewer than 20 percent got at least one shot.
Swine flu that can resist treatment with Roche Holding AG’s Tamiflu is also harder to spread to other people, according to World Health Organization officials.
Almost two dozen people have developed swine flu infections that don’t respond to Tamiflu, a mainstay of therapy for the outbreak that began in April. The genetic mutation that helps the virus evade the drug also thwarts its transmission, so the infection isn’t passed on to other patients, said David Mercer, acting head of the communicable diseases unit of the WHO’s European region.
The Food and Drug Administration on Tuesday approved vaccines designed to protect against the H1N1 influenza virus, a key step before starting a vaccination campaign.
The approval was announced by Health and Human Services Secretary Kathleen Sebelius at a hearing that was held by the House Energy and Commerce Committee.
An FDA spokeswoman said the agency approved vaccines made by a unit of Sanofi-Aventis SA, Novartis AG, CSL Ltd. and AstraZeneca PLC's MedImmune unit.

In documents posted online, the FDA said Cervarix — Glaxo's vaccine against human papilloma virus or HPV — successfully blocked the two most cancerous strains of the virus nearly 93 percent of the time.
The main study of the vaccine enrolled more than 18,000 women who either received Cervarix or a sham treatment. The FDA said the vaccine appears to fight the HPV virus for more than six years, based on company data. Side effects were minor, such as pain and swelling at the injection site.
