Here’s what you need to know about helmet laws in New Jersey

More than 200 New Jersey lawmakers signed a letter Tuesday calling for an end to the helmet law, which allows parents to get permission from a doctor before giving their children their first shots, or to give them their first shot if they’ve been vaccinated.

The letter, signed by more than 20 lawmakers, calls on Gov.

Chris Christie to repeal the law, as well as to end the state’s ban on children under 6 getting their first vaccine.

The legislation, signed into law by Christie in 2015, allowed doctors to refuse a child’s request to get a second shot if the child’s first shot had already been given, and if a child has a history of serious illnesses.

But a federal judge ordered the law lifted in February, ruling it was unconstitutional because it required parental permission before giving a child their first dose of a shot.
