A huge win for sure. But I’d be cautious about calling this bill “anti-vax” — more people are hesitant about vaccines (having questions is okay!) than they are anti. This bill was more about individual choice vs. public good. It’s public health ethics in real time!

HB 1811 would have repealed statutory immunization requirements for children, potentially increasing the prevalence of vaccine-preventable diseases including mumps, poliomyelitis, & rubella. Overturning the committee’s OTP recommendation is a victory for Granite Staters’ health. #NHpolitics

Here's our weekly highlight of a few of the bills we 💙 coming to the NH House floor tomorrow that will lower costs, help first responders, and make registering to vote a little easier for Granite Staters. #NHPolitics
Graphic with a fridge front as the background.  Colorful letter-shaped magnets spell out "some bills we" and then a heart and a note that says "on the NH House Floor this week." There are four notes taped on the fridge. One reads: HB 1600: Makes registering to vote a little easier by streamlining infro between the DMV and local town clerks." The second is: HB 1705: Gives small towns the ability to offer the state Employee Assistance Program to our local first responders." Another reads: HB1492: Saves people money by protecting drivers from mystery tow fees that they can't afford during an emergency." The last one reads: "HB1718: Changes net metering rules so batteries charged by solar can send power to the grid (and lower energy costs!)." In the lower right hand corner there is a calendar for February 2026 that has all the days up to the 19th crossed off. The 19th is circled in red.
