Vaccines work to prevent at least 2 to 3 million deaths each year worldwide.
Tragically, either because of errors or contamination, vaccines can sometimes actually cause people to get sick.
This can happen when health workers:
- use a reconstituted vaccine after six hours – live vaccines can quickly become contaminated if they are kept and used for too long a time
- mixup diluents – in addition to using the wrong diluent vaccination tragedies can occur when a dangerous medication is used instead of a vaccine’s standard diluent
- improperly handle vaccines – breaking the cold chain
- a vaccine is given to someone with a true medical contraindication
Fortunately, these situations are rare.
History of Vaccination Tragedies
With billions of doses of vaccines being given each year, it is likely not surprising that we see some problems. But when many of those vaccines are being given to kids, even one mishap, especially if it leads to life-threatening complications, is too many.
That’s why many safe guards have been put in place in the manufacturer and distribution of modern vaccines, so that we don’t see these types of vaccine tragedies:
- the Cutter Incident, when, in 1955, at least 56 people developed polio and 5 children died after being vaccinated with inactivated polio vaccine that was poorly manufactured by Cutter Laboratories and still contained live polio virus
- hepatitis-contaminated yellow fever vaccines – some lots of yellow fever vaccines used in the military in 1942 were unintentionally contaminated with the hepatitis B virus
- the Lubeck Disaster – 75 children died and others got tuberculosis in 1929 Germany after there was a mixup between the BCG vaccine and the strain of Mycobacterium tuberculosis that causes tuberculosis. The BCG vaccine was supposed to be made with a weakened strain of Mycobacterium bovis bacteria instead.
- the Bundaberg incident – 12 children died in Australia in 1928 after being given contaminated diphtheria vaccine from a multidose vial without preservative
- tetanus contaminated smallpox vaccine in the 1890s and early 20th century
Although vaccines are much safer now, some rare incidents still occur.
Fifteen infants died and 75 children got sick in Syria in 2014 after they received a neuromuscular blocking agent, atracurium, instead of the measles vaccine they were supposed to get. How? The measles vaccine that was being used is mixed with a diluent, but instead of using the proper diluent, the health worker unintentionally used a bottle of atracurium instead.
In 2015, at least two kids died and 29 got sick in Chiapas, Mexico, among 52 children who were vaccinated. The children were reportedly given a BCG vaccine, the rotavirus vaccine, and/or a hepatitis B vaccine that day. However, the only vaccine that all of the sick children received in common was the hepatitis B vaccine. Since 130,000 doses from the same batch of vaccines had been given in the area, it was not thought to be a manufacturing problem or widespread issue. It was instead bacterial contamination of hepatitis B vaccine vials at that one clinic.
Fifteen children died in 2017 in a village in South Sudan after a poorly trained team that wasn’t adhering to WHO immunization safety standards used the same syringe to reconstitute measles vaccines over a four day period. They also didn’t keep the vaccine vials refrigerated.
“A single reconstitution syringe was used for multiple vaccine vials for the entire four days of the campaign instead of being discarded after single use. The reuse of the reconstitution syringe causes it to become contaminated which in turn contaminates the measles vaccine vials and infects the vaccinated children.”

As you can imagine, the conditions that led to these tragedies aren’t present when most kids get vaccinated.
Even in developing countries, most children get vaccinated by people adhering to WHO immunization safety standards. Why did they happened then? Both Syria and South Sudan have been rocked by war for years, leading to a breakdown in the ability to provide routine health care, even as basic as getting kids vaccinated. And Comunidad La Pimienta, Simojovel, Chiapas is a very poor part of southern Mexico.
These kinds of tragedies aren’t going to happen at your pediatrician’s office, as they don’t even have drugs like atracurium.
What Happened in Samoa?
In Samoa, four years after the deaths of the children in Syria, two children died within minutes of being vaccinated on the same day in the same hospital on the island of Savai’i.
Not surprisingly, as health officials investigate the cause, use of the MMR vaccine was suspended in Samoa.
So what happened?
On 4 June 2019, both nurses pleaded guilty to negligence causing manslaughter. On 2 August, both nurses were sentenced to five years in prison. During the sentencing hearing, it was confirmed that one of the nurses mixed the MMR vaccine powder with expired muscle relaxant anaesthetic instead of water for injection supplied in a vial with the vaccine. Eight Samoan speaking New Zealand nurses visited Samoa in June to provide training for vaccinating nurses at district hospitals.Infant deaths in Samoa a tragic outcome from error preparing MMR vaccine
As suspected, since it happened so quickly, it ended up being a mix-up with the diluent, as happened in Syria. A five dose vial of MMR is used in Samoa, which means that unlike premixed vaccines, it does have to be mixed with a diluent.
Unfortunately, we are now hearing of a case in Cuba.
The Ministry of Health in Cuba released a statement a few days after her death:
“Between October 7 and 8 of this year, three one-year-old children were diagnosed with an adverse event associated with vaccination with PRS, which protects against Mumps, Rubella and Measles, this is applied according to official scheme to children one and six years old.
All had been vaccinated on October 7 at the “Betancourt Neninger” Polyclinic in the municipality of Habana del Este, province of Havana, and immediately after symptoms appeared, they were admitted and received medical attention by professionals of high scientific level in the Pediatric Hospitals ” Borrás Marfán ”and Centro Habana.
Through the active research carried out on all children vaccinated in that Health Area, two more children were detected with symptoms, which motivated their admission.
Painfully on October 9 at night, the one-year-old girl Paloma Domínguez Caballero dies, admitted to the “Borrás Marfán” Hospital as a result of complications. The remaining four children remain admitted: one with intensive attention, which is stable and the others evolve favorably.
The system of active surveillance of the events associated with vaccination carried out in the country has not identified any other children with symptoms.
The PRS vaccine has been used for years in Cuba, imported from India, is endorsed by the World Health Organization and certified by the Center for State Control of Medicines, Equipment and Medical Devices (CECMED).
A Commission of the Ministry of Public Health investigates the causes that caused this unfortunate event.”Official Note from the Ministry of Public Health on adverse event associated with vaccination with PRS (computer translation)
Unlike the case in Samoa and Syria, this one sounds like contamination.
It is known that vaccine vials can be contaminated with Staphylococcus bacteria if they are mishandled. Although Staphylococcus bacteria can directly cause infections, they can also release a toxin that can cause toxic shock syndrome (TSS).
There have been reports of TSS following vaccination in the past, usually with vaccines that don’t use preservatives, with symptoms developing over four to 24 hours.
Fortunately, these kinds of tragedies are very rar. Remember that billions of doses of vaccines are given each year without problems, saving millions of lives.
That some folks would use these rare tragedies to scare parents from vaccinating and protecting their kids is shameful. But that’s the modern anti-vaccine movement…
What to Know About Vaccination Tragedies
Kids shouldn’t get sick or die after getting vaccinated. Fortunately, they rarely do, except in extreme circumstances that can make it more likely for errors to occur.

“Tragically, either because of errors or contamination, vaccines can sometimes actually cause people to get sick (Ed. and die; you forgot that part). This can happen when health workers:…”
So, a reasonable inference from those two statements is that, on those “rare” occasions, the vaccine itself is never to blame, but rather “health workers.” Is this what you’re actually saying?
Also, I’m curious: at what point in time is a vaccine “tragedy” no longer explicitly tied to the vaccine? After 2 weeks? One week? 72 hours?
