New Jerseyans opposed to a vaccine exemption bill protested outside the New Jersey State House in Trenton Monday afternoon.

The bill would put limits on which children are exempt from getting the vaccinations required to be allowed to attend public schools in the state.

The bill passed through the state Assembly last month. But state senators could not agree on the bill and put off a vote.

Parents opposed to the bill say that it infringes on their parental rights and religious freedom.

In attendance at Monday’s rally was Robert F. Kennedy Jr., an anti-vaccination activist.

"We have the most aggressive vaccine schedule of any country in the world, and has it given us the healthiest children? No! It has given us the sickest children,” Kennedy said.

The bill will be brought back up in the state Senate later this week.
