BROOKLYN - City officials are trying to get more children to take the flu shot following a rise in flu cases.

Officials released a report that shows that one third of children under five didn't get vaccinated in the past year.

Health experts say that the flu shot can be critical for kids.

"The very young are at risk to get terrible complications from the flu and nothing could be worse than to have your very young child with this infection and having a bad complication and even dying," said SUNY Downstate Medical Director Michael Lanigan.

According to health officials, the flu counts as the third leading cause of death in New York City.
