Two flu shots are better than one (with some exceptions ...)

Despite side effects of a second dose, the argument has been made the a second dose is beneficial.

"The Agency noted that the second dose increases the immune response against pandemic influenza. The Agency has recommended that this information be included in the prescribing information, and be taken into consideration when deciding whether to give a second dose to children. This follows the review of new GlaxoSmithKline data from an ongoing clinical trial in children aged from six months to three years."

The Agency is known as the European Medicines Agency(EMEA) and clearly noted that a  second dose boosted the children immune responses against swine flu.

The argument against a second dosing are the following findings:

1. Children having their second dose of the swine flu vaccine may develop a high fever

2. They are likely to suffer a fever > 38 deg C (100 deg F) after the second dosing.

3. Increased soreness, drowsiness, irritability and loss of appetite is observed after the second vaccination dose of 0.25m Pandremix vaccine despite the doses being spaced at least three weeks apart.
