from 314 of 314 written submissionsHB664 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.
- No currently mandated vaccine has been placebo-testedSupport43 of 314 reviewed
The most common argument is that none of the vaccines currently required for school attendance were tested against an inert placebo, only against other vaccines, and that requiring true placebo-controlled trials is a reasonable scientific safety standard.
“Not a single one of them was tested against a placebo. They were tested against other vaccines. So as long as the side effects of the vaccine were less or not much worse than the previous vaccine, it was considered "safe,"”

- Bodily autonomy and parental choice should govern vaccinationSupport11 of 314 reviewed
Many supporters argue that individuals and parents, not the state, should decide on vaccination, framing mandates as government overreach on personal medical decisions.
“I am in support of every individual having complete control over their bodies and no government or organization should tell them they should have to submit to a medical tyranny.”

- Distrust of pharmaceutical industry profit motivesSupport3 of 314 reviewed
A smaller number of submissions argue that vaccine requirements primarily serve pharmaceutical company profits rather than public health, and that manufacturers' legal immunity from liability justifies stricter testing standards.
“The only interest served by vaccine requirements are pharmaceutical companies and their investors.”

- Personal experience of vaccine injurySupport2 of 314 reviewed
A few supporters describe a personal or family experience of an adverse vaccine reaction as motivation for wanting stronger, placebo-based safety testing before vaccines are mandated.
“My son had a serious adverse reaction to a vaccine at age 3. We have really struggled with saying no thank you ever since.”

- Placebo trials are often unethical or infeasible once a vaccine existsOppose41 of 314 reviewed
Many opponents argue that withholding a known effective vaccine from a control group to use an inert placebo is unethical and violates research standards, so vaccines are properly tested against existing vaccines or active comparators instead.
“In pediatric vaccine research, using an inert placebo (like saline) is often considered unethical if an effective vaccine already exists. Withholding a known, effective vaccine in favor of a placebo would expose children to preventable diseases, violating ethical standards”
— Alexandra Carter, Rochester · #503149 — read full submission →
“study participants who are randomized to receive an "inert placebo" in the control arm of a study would be receiving substandard care because they would not receive an available, effective drug”
— Lyn Lindpaintner, Concord · #504359 — read full submission →
“This bill requires that only vaccines tested with placebos and would leave those participating in trials vulnerable to diseases that could otherwise be prevented. This approach is unethical and unnecessary.”
— Patricia Anastasia, Londonderry · #505315 — read full submission →
- Vaccines protect public health; weakening requirements risks outbreaksOppose100 of 314 reviewed
A large number of submissions argue vaccines are already proven safe and effective, that requirements protect vulnerable and immunocompromised residents through herd immunity, and that loosening them risks a return of diseases like measles and polio, citing ongoing outbreaks as evidence.
“Vaccine requirements protect kids and adults from risks of serious disease, complications, and contagion to others. Some people can't get vaccinated because they are immunocompromised. We need to protect ourselves and these vulnerable groups”
— John Stetser, Hillsboro · #505486 — read full submission →
“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”

- Bill is redundant given existing FDA/CDC approval processOppose21 of 314 reviewed
Some opponents contend that mandated vaccines already undergo rigorous, multi-stage FDA and CDC testing and post-market surveillance, making the bill's placebo requirement unnecessary and duplicative.
“This bill is redundant and requires testing that would have already been done in the FDA approval process for the vaccine.”
— Sharon Racusin, Hanover · #503450 — read full submission →
“The current vaccine approval process follows rigorous, evidence-based protocols overseen by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC).”
— Sarah Abberton, Bow · #505913 — read full submission →
- Bill is anti-science and politically motivatedOppose40 of 314 reviewed
Several submissions characterize the bill as a disguised anti-vaccine measure driven by political ideology rather than science, arguing legislators lack the medical or immunology expertise to set clinical trial standards.
“The authors of this bill have no background in immunology or medicine. Saying that vaccines must be tested against an inert placebo is an arbitrary standard meant to confuse people”
— Christine Arsnow, New London · #503503 — read full submission →

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 …
I approve of this bill.
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.
I wholeheartedly support this bill!!!
Please support science
I believe that children should receive vaccination against disease for their safety and the safety of the community
I support
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.
I wholeheartedly oppose this bill because it puts our kids at risk!!
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. See: https://www.newsweek.com/fact-check-rare-vaccine-stop-all-transmission-infection-1638518 https://www.politifact.com/factchecks/2025/jan/02/ron-johnson/yes-there-have-been-placebo-controlled-studies-on/ https://www.sciencealert.com/few-vaccines-actually-prevent-infection-here-s-why-that-s-not-a-problem-with-covid-19
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.!
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.
Any required vaccines should be supported by the gold standard in science which is a double blind placebo controlled study.
Any required vaccines should be supported by the food standard in science which is a double blind placebo controlled study.
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.
I support this bill because it adds the minimum of necessary procedures to more accurately determine the effectiveness of a vaccine.
