For 13-year-old Brandon Marti, the intranasal vaccine felt "good," "cold" and "watery" at the Children's Hospital at Montefiore in the Bronx, New York, on Tuesday.

Marti, among the first to get vaccinated against the novel H1N1 influenza virus this week, said he would tell his friends and classmates that "the swine flu vaccine is good, and protects me from getting the swine flu."

New York has received a shipment of 68,000 doses of the FluMist variety vaccine. This form was made available before the injectable kind because it was ready first, said Thomas Skinner, spokesperson for the Centers for Disease Control and Prevention.
