Gov. Martin O'Malley has signed an executive order to enlist extra medical personnel to administer swine flu vaccinations, if needed.

The order signed Friday will help boost emergency medical personnel and other licensed medical professionals who volunteer to be part of the state's swine flu response effort to give vaccinations.

Now, emergency medical personnel are allowed limited legal authority to vaccinate each other, not the general public.

The order also gives the state's health secretary the authority to enlist help from licensed medical professional to administer the vaccine if they have the training to do so.
