Stamford Hospital officials say they are down to their last batch of nasal mist swine flu vaccinations before supplies of the vaccine shots are delivered.

Doctors say two groups of people have been prioritized to receive the remaining nasal spray vaccines, including children between the ages of 2 and 6 and health care workers. Doctors say it is critical for health care workers to be vaccinated since they deal with people with vulnerable immune systems.

Some residents say they are wary of the new vaccine since the swine flu vaccines developed in 1976 were linked to several cases of Guillain Barre Syndrome, a neurological condition that causes temporary muscle paralysis.
