(Nov. 12) -- A Virginia high school student was released from the hospital Tuesday after developing a rare disease within hours of being vaccinated against swine flu, MSNBC reported.

Jordan McFarland, 14, of Alexandria, Va., experienced severe headaches, muscle spasms and leg weakness after getting the H1N1 vaccine. His parents told MSNBC that doctors diagnosed him with Guillain-Barre syndrome, a disorder that causes the body's immune system to attack part of the nervous system. Only a handful of cases of the syndrome have been reported in relation to the vaccine.

"The doctor said I'll recover fully, but it's going to take some time," said Jordan, who will need physical therapy and might have to move around with the aid of a walker for a few weeks.

An official from the Centers for Disease Control and Prevention said there was no clear link between the vaccine and the syndrome, the television network reported.

In other H1N1 news from the past week:

-- The CDC said 4,000 or more Americans have likely died from swine flu, quadruple an earlier estimate. In a typical winter, seasonal flu strains cause 36,000 deaths, the vast majority in people over 65. Seasonal influenza doesn't usually start circulating until November. Swine flu began a big climb in September, leading to what CDC called unprecedented high levels of illness so early in a season — and no way to know when the flu will peak.

-- Sen. Chris Dodd, D-Conn., announced that he will push emergency legislation to require businesses to provide up to seven days of paid sick leave for workers who get H1N1 or who need to take care of children who come down with it.

-- The World Health Organization changed its guidance on H1N1, saying that early treatment can help prevent death. Doctors should give antiviral medications as soon as possible to high-risk H1N1 patients, including very young children, pregnant women and the elderly.
