HB664 would bar the state from requiring any childhood vaccine for school attendance unless it has been tested against an inert placebo in clinical trials. Supporters frame this as a basic scientific and ethical safety standard that no currently mandated vaccine meets, while opponents argue that placebo-controlled trials are often scientifically inappropriate or unethical once an effective vaccine exists, and that the bill would weaken vaccination requirements and endanger public health amid disease outbreaks such as measles.

Vaccinations are vital to modern society. Obviously.

I strongly oppose this bill.

It is time for gold standard of health care to come back. Full transparency is needed- we need to know (and be able to verify) that any health recommendations made are backed by sound science. Quality in healthcare should be the standard- not whether or not big Pharma is going to make money!.!

This is a solution in search of a problem. Medical researchers already prove the veracity & safety of vaccines before they're released to the public. Legislators need to stop imagining that they're smarter than medical professionals & stop trying to do jobs they are not qualified for. Stay in your lane!

This bill provides that childhood immunization requirements shall not require a vaccine that has not been tested with an inert placebo in clinical trials. This bill would ban childhood vaccines unless they were tested using only an inert (non-active) placebo; something that isn’t always ethical or practical when effective vaccines already exist. It ignores how modern vaccines are safely tested and could block lifesaving immunizations for kids.

I am a 72 year old RNC in Maternal Child health for 48 years. We saved lives everyday with vaccines for ourselves and the Mother newborn cuplet. This Bill will allow this population to die . Just like my generation died before these laws were passed by decent Human Beings. You all have humans in your lives …Do the right thing …

Melissa JonesSupportMeredith, NHfor MyselfMar 12, 2025

I approve of this bill.

AnneMarie WinklerOpposeDover, NHfor MyselfMar 12, 2025

DO NOT IGNORE THE HEALTH OF THE RESIDENTS OF THIS STATE!!! Mine and my daughter’s life depend on vaccines and the previous vote completely ignored the unanimous opposition to these destruction of our public health!!! Vaccine, save lives, and even Mr. Kennedy and Trump have made and as recently as last week promoted vaccines! Anyone who votes in favor of this bill I will hold accountable. I will ensure you’re not elected. I will put every single penny. I have to make sure of it. I will call your donors and make sure that they are aware that you have jeopardized our lives.

Vaccines are effective and safe. This fear mongering and statements that arent based on science are detrimental to the health of our communities

As someone who is immunocompromised and could be severely impacted or die due to catching easily preventable diseases, I strongly oppose this bill. My life and the lives of many others are literally on the line here.

Sara HansOpposeConcord, NHfor MyselfMar 12, 2025

I wholeheartedly oppose this bill because it puts our kids at risk!!

Terry CarterOpposeDover, NHfor MyselfMar 12, 2025

Please oppose this bill! If you support this bill, you would also support non-tested blood pressure meds, or non-tested diabetes meds. Medical science has done some wonders! We must let people who know what they are doing TEST the drugs we give our children.

As the mother of a 3 year old, someone with elderly parents, and someone who cares about whether the US descends into the Dark Ages of health again, PLEASE STOP BILLS THE REDUCE SUPPORT FOR CRITICAL VACCINATION PROGRAMS AND RESOURCES! Did you have Covid? Did your grandparents face measles? Have you traveled to and seen the devastation of easily preventable diseases in other countries? NH 'representatives' who seek to reduce vaccination support in our state are woefully isolated from reality and do not represent the interests of ANYone's health. The science and evidence support the health and fiscal effectiveness of mainstream vaccination programs, With measles outbreaks happening in several US states, leading to the tragic deaths of at least one unvaccinated child and an adult, it is particularly disturbing that the anti-vaccination crowd at the GOP State House continues to push dangerous bills that would undermine public vaccination campaigns and threaten the safety of all Granite Staters. These bills are anti-science and hide what seems to be the true end game: making vaccination requirements of any kind unenforceable. The two bills here, HB 664 and HB 679, seem to cloak their true purpose with talk of "inert placebo" clinical trials and "preventing transmission of disease" as though these are bright lines that should bar vaccine requirements. The truth is, placebo trials, in fact, can be unethical if a prior vaccine exists and in other situations, too. Also, there are placebos used in vaccine trials that are appropriately not "inert". As to preventing disease transmission, although some vaccines are more effective than others at limiting transmission, vaccines in general help to reduce the risk of serious complications such as hospitalization and death.

I oppose this bill as a member of the public and especially as a retired immunologist. We have limited or irradicated numerous diseased that primarily strike children because of the requirements that school age children be immunized prior to entering school. There is no doubt that this practice should continue to protect all of us, children and adults alike, Just witness the current outbreak of measles in Texas, which is spreading and has already claimed several lives. What are the sponsors of this bills thinking in terms of public safety. Certainly NOT caring for the whole population, including their constituents.!

Tanya PodawiltzOpposeMilford, NHfor MyselfMar 12, 2025

Dear Members of the Health, Human Services and Elderly Affairs Committee, I am writing in strong opposition to HB 664, which proposes that childhood immunization requirements may only include vaccines that have been tested with an inert placebo in clinical trials. While I understand the intent to ensure transparency and safety in medical protocols, this bill is based on a flawed understanding of how vaccines are tested, approved, and monitored in the United States. This legislation undermines the rigorous and multi-layered process that vaccines already go through before being recommended for use in children. The FDA and CDC already require extensive safety and efficacy trials, including post-marketing surveillance. The insistence on an "inert placebo" as a standard discredits the scientific reality that many vaccines are tested against active comparators for ethical and practical reasons, particularly when effective vaccines already exist. By adding vague and scientifically unfounded restrictions to what constitutes valid vaccine research, HB 664 could weaken New Hampshire’s public health infrastructure, confuse the public, and ultimately reduce childhood immunization rates. This poses a serious threat to our communities, especially to those who are medically vulnerable and rely on herd immunity to stay safe. Public health decisions should be guided by established science and expert consensus, not by misinformation or misunderstandings of clinical trial design. I urge you to vote no on HB 664 and continue to uphold evidence-based policies that protect the health of New Hampshire's children and communities.

As the mother of a vaccine injured child I hole heartedly support.

I support this bill to require only vaccines that are backed for safety by a double blind study.

Brian NeilSupportCanterbury, NHfor MyselfMar 12, 2025

Any required vaccines should be supported by the gold standard in science which is a double blind placebo controlled study.

Amanda NeilSupportCanterbury, NHfor MyselfMar 12, 2025

Any required vaccines should be supported by the food standard in science which is a double blind placebo controlled study.

Laura CondonSupportBedford, NHfor MyselfMar 12, 2025

Please support HB664-A as OTP. It is essential ethically and morally that if vaccines are required for children that they be held to the highest standards in science and medicine. It is without dispute that vaccines carry risk of harm including disability and death. Manufacturers have immunity from liability for this very reason. Therefore, when imposing mandates, we must assure the parents and children of NH that we will ensure that the scientific gold standard of using inert placebos in clinical trials has been a determining factor in considered in deciding vaccine mandates. We should not accept the haphazard practice of comparing new vaccines to old vaccines when looking for adverse effects as this intentionally creates the illusion that if the new vaccine does not show more adverse effects than the old vaccine, that it will be considered "safe". That's absolute scientific nonsense and is not the way all other drugs are approved for public use. Our children deserve better. Because vaccine requirements are imposed on healthy children with naturally developing immune systems, it is absolutely essential that we not abandon the scientific gold standard for vaccines. How could anyone in good conscience accept a lesser standard for our children? Please vote HB 664-A as OTP. Thank you.

Donna MeuseSupportKingston, NHfor MyselfMar 12, 2025

I support this bill because it adds the minimum of necessary procedures to more accurately determine the effectiveness of a vaccine.
