A new federal law requires that parents get their kids vaccinated before they can enroll in a state or federally-funded program.
The law, which was signed by President Donald Trump on Thursday, requires states to have mandatory vaccinations of children at ages six, eight, 10, 12 and 14, as well as adults ages 18 and over.
It also requires that states submit annual reports of immunization rates and provide information on who gets the vaccine.
States can also opt to opt out of the program and have their vaccine coverage be determined by the federal government.
The federal law was initially signed by Trump and passed by the House of Representatives in May, but was put on hold by the Senate.
The House approved the bill by a voice vote, but the Senate has to approve the legislation before it can be signed into law.
Under the new law, parents who don’t have their kids up for vaccinations and who have an income of less than $150,000 per year are not required to get them.
That’s a significant increase from the current law, where parents could get the vaccine regardless of income.
But the new legislation does include a provision that would allow states to opt to waive certain requirements in order to have their coverage determined by federal guidelines.
That would mean that states could choose to exempt their residents who live outside the continental United States from mandatory vaccinations.
The bill has also drawn criticism from conservatives, who say it doesn’t go far enough to protect the nation’s children from the disease, and is overly broad in its requirements.
The House version of the bill included a requirement that children receive a measles, rubella, or diphtheria vaccination by January 31, 2019.
The Senate bill does not.
It was not immediately clear if any changes would be made to the Senate version of this bill, which passed the House with bipartisan support last week.
