Submitting a report on VAERS might be one of the easiest things to do/easiest ways to spread false claims. Siri is lying. Again.

This claim has led to the dangerous trend of alternative/delayed/spaced out vaccine schedules which put children in unnecessary risk of disease for longer periods of time. There is no evidence to suggest that deviating from the recommended vaccine schedule is safer or better for children.

To say that the schedule has โ€œtripledโ€ just based on the number of injections and not the components of the vaccines is incredibly misleading.

Our kidsโ€”MY KIDSโ€” are better protected today than any of us were decades ago.

All of these vaccines have < ๐Ÿฎ๐Ÿฌ๐Ÿฌ ๐—ฎ๐—ป๐˜๐—ถ๐—ด๐—ฒ๐—ป๐˜€!

Thatโ€™s because vaccine research and development has made them more effective, more efficient, and less taxing on the immune system.

In 2025, children are vaccinated against ๐—ฆ๐—œ๐—ซ๐—ง๐—˜๐—˜๐—ก diseases - diphtheria, tetanus, pertussis (whopping cough), measles, mumps, rubella polio, haemophilus influenzae type b (Hib), hepatitis B, varicella (chickenpox), hepatitis A, pneumococcal disease, influenza, rotavirus, HPV, and meningococcal.

Of course they visualize the schedule like this because it elicits a strong emotional reactionโ€”especially among new parents. Letโ€™s add some critical context to this imageโ€ฆ

I don't say embarrassment lightly. Meissner is literally having to remind others on the committee of basic virology, like how you can't compare viruses like Yellow Fever (RNA flavivirus) and Hepatitis (DNA hepadnaviridae).

Meissner and Hibbeln are right. This vote will cause harm. ACIP has become an embarrassment.

ACIP's discussion about "informed consent" today is dishonest. The HepB birth dose is not mandatory; it is recommended. Parents & caregivers have always had the right to refuse or delay. This edit is intended to confuse people about public health mandates and make MAHA out to be a freedom hero.

When we say "vaccines are a victim of their own success," this is exactly what we mean: ACIP is trying to justify altering the very vaccine recommendation that is the reason why we're not seeing much disease [Hep B]. The HBV vaccine is *that* successful, and safe, and effective.

From the โ€œfirst consolidated World Health Organization report on viral hepatitis epidemiology, service coverage and product access,โ€

โ€œGlobally, 115 countries have introduced universal hepatitis B birth-dose vaccination, and 45% of infants received the hepatitis B birth dose within the first 24 hours of birth in
2022. Twenty-three countries have selective programmes with targeted provision of the hepatitis B birth dose (the vaccine is provided to the infants of mothers who are HBsAg positive). Infant immunization schedules in 190 countries include the hepatitis B vaccine. Of the 38
WHO focus countries for the viral hepatitis response, 25 have introduced birth-dose programmes and all provide the hepatitis B vaccine (usually as part of pentavalent vaccines) in their infant vaccination programme. In theory, if these vaccines are included in the national programme, all children should have access; however, in practice, coverage varies widely across regions and countries (Table 3.23 and Fig. 3.32). Chapter 4 presents detailed information for the 38 WHO focus countries for viral hepatitis.โ€

Did you know?

190 countries have infant immunization schedules that include the Hep B vaccine

115 countries recommend a universal birth-dose of the Hep B vaccine, one of the key actions WHO recommends to reduce Hep B prevalence

Secretary Kennedy presents a clear and present danger to the American people and their families. This week, even more of our colleagues in the fields of medicine, public health and patient advocacy join us in calling for his resignation.

We vaccinate to *reduce harm.* Vaccines are not immunity passports with absolute guarantees of no infection. What drives me crazy is that these people know that. By repeating these claims, they validate and endorse vaccine refusal.

Has everyone forgotten the endpoints of the original COVID-19 vaccine clinical trials? They were designed to prevent hospitalizations & deaths. Transmission reduction was observed, but total transmission prevention was never promised.
This is a bad-faith argument against vaccine effectiveness.

Meissner pushing the dying "with COVID" vs "from COVID" and arguing with an actual epidemiologist about disease burden and cumulative rates is shameful.

He just said it's "not that high" with regard to pediatric severe outcomes.

Unbelievable ignorance about population health & basic statistics.

It bugs me when people say that RFK Jr. and the members of ACIP arenโ€™t โ€œserious peopleโ€.

They are DEADLY serious about taking vaccines away from the people of the United States, and they have the power to do so.

The CDC already recommends MMR over MMRV for kids under 4. This is sham science and a giant waste of everyone's time.

EtR (evidence to Recommendations) is gone. We're now forming vaccine policy based on vibes and public opinion.
Mallone admits they are making a decision not based on a safety signal...but on trust? There is no reason to defer the Hep B birth dose except to advance the anti-vaccine agenda.

Comparing against saline in cases where a vaccine that has already proven to be safe and effective would be unethical. We cannot withhold interventions and risk causing preventable harm. This legalistic interpretation of placebo-controlled trials is wrong and unscientific.

I *hate* the use of the phrase "true [saline] placebo." It is usually in combination with claims that comparing against saline is the only real/ethical way to measure safety & efficacy. It isn't. That phrase has captivated an entire population of parents who genuinely want to make informed choices
