Idaho Mom Charged in Twin Deaths Blames Vaccines – But Doctors Say No

What Happened?

An Idaho mother named Andrea Shaw has been charged with the first-degree murders of her 18-month-old twins, Dallas and Tyson. The twins were found dead in their bed in Payette, Idaho, on May 1, 2025.

After their deaths, Shaw said the vaccines the babies got eight days before they died caused their deaths. But doctors who looked at the case say that simply isn’t true.

Important Point: Three doctors who reviewed the case say it was not possible the children died from a vaccine reaction. The official cause of death was suffocation.

What the Doctors Say

Doctors who checked the facts at the request of The Guardian newspaper are very clear:

• Dr. Jake Scott (infectious disease physician at Stanford): “This was not a close call. I can say with confidence what didn’t happen here. It was not the vaccines.”
• Dr. Amesh Adalja (Johns Hopkins): “There’s no biological plausibility to a vaccine suffocating somebody.”
• The three vaccines the twins got are non-live vaccines. The only known way they can cause death is a severe allergic reaction, which happens within minutes or hours — not 8 days later.
• Scott said such a reaction would “absolutely never” kill someone eight days later.

The doctors based their conclusions on:

• The types of vaccines given
• The timing of the deaths
• ER visit records
• Shaw’s own description of symptoms
• The determined cause of death (suffocation)

The Timeline (ELI5 Version)

Here is what happened, step by step:

1. April 23, 2025: Each twin got three shots: DTaP (protects against diphtheria, tetanus, pertussis), hepatitis A, and flu. Shaw’s mother-in-law was there and mentioned the family had reactions to flu shots before, but the nurse said it was fine.
2. April 24, 2025: Shaw took the twins to the ER, saying they had blue lips, lethargy, and sunken eyes. But partial records show only mild symptoms (like feeling warm or fussy — totally normal after shots). Dallas had a temp of 99°F and good eye contact; Tyson was “very active.”
3. April 30, 2025: Shaw told an anti-vaccine group the twins were doing great — active, eating, drinking, talking.
4. May 1, 2025 (morning): Shaw says she found both twins dead in their shared bed.

Important Point: Scott said: “There is no vaccine injury that improves and then kills a child overnight. And certainly not two children in the same night.”

About the Vaccines Themselves

Some people worry about stuff like mercury or eggs in vaccines. Here’s the simple truth for these shots:

• Thimerosal (a preservative with mercury) was removed from kids’ vaccines in the US over 20 years ago. The flu shot Dallas got was single-dose and preservative-free.
• The recorded flu vaccine was not made in hen’s eggs, so it had no egg protein at all.

The Case Against Shaw

Shaw was indicted for murder last month. Her lawyer, Joseph Filicetti, says he doesn’t have to prove vaccines caused it, but thinks they “played a role.” He also questioned if the Guardian’s doctors could judge without full records.

But:

• Prosecutors consulted three doctors who ruled out vaccines, heat, carbon monoxide, and other poisonings.
• Prosecutor Michael Duke said Shaw changed her story about that night (said she saw a child sit up, then said she didn’t).
• Duke told the judge: “This is not a vaccine case. This is a case where a mother, unfortunately, has killed her two children.”
• The judge revoked her $2M bond, worried she was a threat to her new baby born just before arrest.

The Role of Children’s Health Defense (CHD)

CHD is an anti-vaccine group once led by Robert F. Kennedy Jr. Three days after the twins died — before any autopsy — CHD’s Polly Tommey blamed vaccines in a video interview with Shaw.

• CHD published the deaths as a top story and added Shaw as lead plaintiff in a lawsuit against the American Academy of Pediatrics.
• CHD CEO Mary Holland says they still support Shaw, claiming the deaths “follow a typical pattern” of vaccine reaction.
• Dr. Scott criticized CHD: “It finds a tragedy, attaches a vaccine to it, and uses the grief to garner support.”

Summary

Andrea Shaw is charged with murdering her twin toddlers. She and CHD say vaccines killed them, but multiple doctors — including those for prosecutors — say vaccines did not. The kids had mild, normal post-shot symptoms, got better, then died of suffocation. Experts say a vaccine cannot cause death 8 days later or suffocate someone. CHD pushed the vaccine story without waiting for facts.

FAQ

1. Did the vaccines given to the twins cause their death?
No. Three independent doctors and three prosecution doctors say the vaccines did not cause death. The official cause was suffocation.

2. Why do some people think vaccines were to blame?
An anti-vaccine group (CHD) blamed shots before any cause was known and used the tragedy to promote its message. The mother also said vaccines caused it.

3. What kinds of vaccines did the babies get?
They got DTaP (diphtheria, tetanus, whooping cough), hepatitis A, and influenza (flu) vaccines — all non-live and preservative-/egg-free in this case.

4. Can a vaccine reaction happen 8 days later?
For these vaccines, a deadly reaction (severe allergy) would happen in minutes or hours. Doctors say it would never happen 8 days later.

5. What is Children’s Health Defense?
It’s an anti-vaccine organization previously run by RFK Jr. It supports Shaw and used the twins’ deaths to argue vaccines are dangerous, without evidence.
