BROOKLYN - Hundreds of Brooklyn residents lined up to receive free H1N1 vaccinations this weekend.

More than 350 people got the shots Saturday in the city's fourth weekend of giving out free H1N1 vaccines. The shots were available to people between the ages of 4 and 24, pregnant women and those with pre-existing health conditions.

The city hopes the effort to vaccinate New Yorkers will help prevent the spread of the virus.
