Effectiveness of influenza vaccine during pregnancy in preventing hospitalizations and outpatient visits for respiratory illness in pregnant women and their infants.

A study published in the American Journal of Perinatology of vaccine effectiveness in pregnant women in Northern California across five flu seasons found that women who received flu vaccines during pregnancy had the same risk for influenza-like illness as unvaccinated women, and infants born to women who received flu vaccines also had the same risks for influenza or pneumonia as infants born to unvaccinated women. In other words, vaccine status made no difference to whether or not pregnant women or their offspring got the flu.”

Postmarketing adverse drug reactions

A 2013 article in Neurology Clinical Practice calculated that only between 1 and 10 percent of adverse reactions are actually reported by physicians. Applying that calculus, the actual range of deaths following flu vaccination in the past 25 years may be between 5,600 and 56,000

A Perfect Storm: Impact of Genomic Variation and Serial Vaccination on Low Influenza Vaccine Effectiveness During the 2014–2015 Season

In a peer-reviewed study published in Clinical Infectious Diseases in March 2016, a team of Canadian researchers found that people who were vaccinated against the flu three years in a row were actually at higher risk of being infected with the flu.”

Benefits of influenza vaccination on influenza-related mortality among elderly in the US: an unexpected finding

When a team of researchers at the National Institutes of Health compared flu vaccine rates with influenza-related illness over a 19-year period, from 1980 to 1999, they found that deaths from the flu increased as vaccination rates increased. “In conclusion, the increase in elderly influenza vaccination coverage in the U.S. after 1980 was not accompanied by a decline in influenza-related mortality.”

Impact of Influenza Vaccination on Seasonal Mortality in the US Elderly Population

A study, led by a researcher at the National Institute of Allergy and Infectious Diseases and published in the journal Archives of Internal Medicine, found that increasing vaccination coverage did not correlate with declining mortality and the decline in influenza-related mortality could not be attributed to the flu vaccine but was rather the result of naturally acquired immunity. Observational studies crediting the flu vaccine with contributing to decreased deaths from the flu, “substantially overestimate vaccination benefit.”

Febrile Seizure Risk after Vaccination in Children One to Five Months of Age Pediatric Neurology

Vaccination in children aged three to five months was associated with a large relative risk of febrile seizure on the day of and the day after vaccination. [Febrile seizures can lead to permanent seizure disorders including epilepsy, see our page on seizures]

Vaccine administration and the development of immune thrombocytopenic purpura in children Human Vaccines & Immunotherapies.

Immune thrombocytopenic purpura (ITP) is an adverse event that can follow vaccine administration, and may limit vaccine use because little is known about which vaccines it may follow, its real incidence and severity, the risk of chronic disease, or the possibility of recurrences after new doses of the same vaccine.

Adverse events following administration to pregnant women of influenza A (H1N1) 2009 monovalent vaccine reported to the Vaccine Adverse Event Reporting System [Death and miscarriages reported to VAERS after influenza vaccine] Vaccine

VAERS received 294 reports of AEs (Adverse Events) in pregnant women who received 2009-H1N1 vaccine. Two maternal deaths were reported. Fifty-nine women (20.1%) were hospitalized. We verified 131 pregnancy-specific outcomes: 95 spontaneous abortions (<20 weeks); 18 stillbirths (≥20 weeks).

Acute Lung Injury Accompanying Alveolar Hemorrhage Associated with Flu Vaccination in the Elderly Internal medicine 

We describe a case of acute lung injury resulting from a pathologically confirmed alveolar hemorrhage, which may have been closely related to a preceding vaccination for influenza [flu]. We should consider a vaccine-related adverse reaction as a potential cause of pulmonary disease. Pulmonary injury or alveolar hemorrhage in the influenza season should always prompt physicians to consider the possibility of flu vaccination- related ADR.

Influenza vaccination and Guillain Barre syndrome

Influenza vaccination increases the risk of Guillain Barre syndrome (GBS)

Impact of influenza vaccination on seasonal mortality in the US elderly population

We could not correlate increasing vaccination coverage after 1980 with declining mortality rates in any age group. Because fewer than 10% of all winter deaths were attributable to influenza in any season, we conclude that observational studies substantially overestimate vaccination benefit.

Influenza vaccination for healthcare workers who care for people aged 60 or older living in long-term care institutions

The results for specific outcomes: laboratory-proven influenza or its complications (lower respiratory tract infection, or hospitalisation or death due to lower respiratory tract illness) did not identify a benefit of healthcare worker vaccination on these key outcomes. This review does not provide reasonable evidence to support the vaccination of healthcare workers to prevent influenza in those aged 60 years or older resident in LTCIs.

Influenza vaccines: time for a rethink

I show that there is no good evidence that vaccines reduce serious complications of influenza, the outcomes the policy is meant to address. In addition, there are potential vaccine-related harms, as unexpected and serious adverse effects of influenza vaccines have occurred.

Are US flu death figures more PR than science?

If flu is in fact not a major cause of death, this public relations approach is surely exaggerated.

Acute disseminated encephalomyelitis following inactivated influenza vaccination in the Brazilian Amazon: a case report

“Here, we describe a case of acute disseminated encephalomyelitis (ADEM) that occurred during a plausible risk interval following inactivated influenza vaccination in a previously healthy 27-year-old man from Manaus, Brazil. He was treated with intravenous methylprednisolone and immunoglobulin. One-month follow-up revealed resolution of the brain lesions, but not of the spinal cord lesions. No recurrence or progression of the main neurological symptoms was observed. After two years of monitoring, the patient continues to experience weak lower limbs and urinary retention. Thus, we recommend that ADEM should be considered in a patient presenting with neurological symptoms after influenza vaccination.” Revista da Sociedade Brasileira de Medicina Tropical 2015

Exacerbation of pemphigus after influenza vaccination.

“Pemphigus is a rare autoimmune disease characterized by flaccid blisters and erosions on skin and mucous epithelia. A critical event in its pathogenesis is production of antidesmoglein antibodies, which mediate the loss of intercellular adhesion in epithelia, leading to blister formation. Multiple environmental factors (ultraviolet radiation, trauma, drugs, infective agents) have been suggested as possible triggers of pemphigus. Occasionally, the disease has been reported to follow viral and bacterial vaccination. We describe a patient who experienced exacerbation of pemphigus shortly after administration of the influenza vaccination on two separate occasions. We review the literature, suggest possible explanations for a causal relationship, and discuss the administration of vaccination to these patients.” Clinical and Experimental Dermatology 2008

Guillain-Barre syndrome occurring after rabies vaccination.

“A variety of events are associated with the onset of Guillain-Barre syndrome, including vaccinations and vaccines. These are the swine influenza vaccine, oral poliovirus vaccine and rabies vaccine. Rabies is a uniformly fatal disease. It is preventable if World Health Organization (WHO) guidelines for post exposure treatment (PET) are followed. These include local treatment of wound, passive immunization with rabies immunoglobulins and administration of a efficacious vaccine. Cell culture vaccines are highly immunogenic with fewer side effects, but are costly. For that reason neurotissue vaccines are still widely used in Pakistan, although they are less immunogenic with higher incidence of neuroparalytic complications. We report a case of Guillain-Barre syndrome secondary to sheep brain anti-rabies vaccine in a young boy, who presented with lower limb weakness with total recovery after treatment.” Pakistan Medical Association

Inflammation-related effects of adjuvant influenza A vaccination on platelet activation and cardiac autonomic function

Together with an inflammatory reaction, influenza A vaccine induced platelet activation and sympathovagal imbalance towards adrenergic predominance.

Ischaemic stroke and influenza A H1N1 vaccination: a case report.

“We report a 75-year-old male patient who suffered posterior circulation ischaemia after influenza A/H1N1 vaccination. Vaccination provokes a variable magnitude of inflammatory and immunological response that modifies the risk for ischaemic stroke. Whereas a causal relation between vaccination and ischaemic stroke is still unsettled, an inflammatory/immunological response after vaccination may trigger thrombosis superimposing a pre-existing prothrombotic state. Careful monitoring is strongly suggested for individuals who received H1N1 vaccine, especially those with high ischaemic stroke risk.” Archives of Medical Science 2011

“From 2011 to 2016, we identified 4479 ASIA cases, of them 305 fulfilled arbitrary criteria of severe ASIA including our case presentation and 11 deaths. The majority of severe ASIA cases were related to HPV vaccine, silicone, influenza vaccine and mineral oil injections. The interval from exposition to severe manifestation was from 2 days to 23 years. (1) This is the first study that analyzes all cases published on ASIA with severe manifestations. (2) The current HPV vaccine is both effective and generally safe. However, it should be noted that severe autoimmune side effects have been reported in several studies. Severe ASIA may be observed after influenza vaccines, and other vaccines. (3) Efforts should be made to discover the connection between adjuvants, autoimmunity and autoimmune diseases, because there is an increase in cases severe and life-threatening of ASIA.”

Subacute thyroiditis and dyserythropoesis after influenza vaccination suggesting immune dysregulation

We describe a case of subacute thyroiditis and dyserythropoesis occurring shortly after administration of an influenza vaccine in a 55-year-old man with history of diabetes and psoriasis, family history of autoimmunity without clinical evidence of acute viral infection prior to the onset of symptoms.” Boletín de la Asociación Médica de Puerto Rico 2011

Subacute thyroiditis following influenza vaccine (Vaxigrip) in a young female

This report details a case of SAT {Subacute thyroiditis} possibly associated with influenza vaccine (Vaxigrip) in a young female. The diagnosis, therapeutic management and outcome are discussed. The Kaohsiung Journal of Medical Sciences 2006

Subacute thyroiditis following seasonal influenza vaccination

This case shows SAT as a rare condition following vaccination.. Thus, SAT {subacute thyroiditis} should be considered as a possible outcome following influenza vaccination and flu-like syndrome.” Human Vaccines & Immunotherapeutics 2017

Subdeltoid/subacromial bursitis associated with influenza vaccination

A 76-year-old male presented with subacromial/subdeltoid bursitis following influenza vaccine administration into the left deltoid muscle. This shoulder injury related to vaccine administration (SIRVA) could have been prevented by the use of a safe, evidence based protocol for the intramuscular injection of the deltoid muscle.” Human Vaccines & Immunotherapeutics 2014

Surveillance of adverse events after the first trivalent inactivated influenza vaccine produced in mammalian cell culture (Flucelvax(®)) reported to the Vaccine Adverse Event Reporting System (VAERS), United States, 2013-2015.

“Among 309 reports with an AE documented, 19 (6.1%) were serious and the most common categories were 152 (49.2%) general disorders and administration site conditions (mostly injection site and systemic reactions) and 73 (23.6%) immune system disorders with two reports of anaphylaxis. Four reports of GBS were submitted. Disproportional reporting was identified for ‘drug administered to patient of inappropriate age.” Vaccine 2015

Temporal Association of Certain Neuropsychiatric Disorders Following Vaccination of Children and Adolescents: A Pilot Case-Control Study

“This pilot epidemiologic analysis implies that the onset of some neuropsychiatric disorders may be temporally related to prior vaccinations in a subset of individuals.” Frontiers in Psychiatry 2017

Ten-Year Follow-Up Study for Safety of Adjuvant 65 Influenza Vaccine in Man (37469)

The total influenza vaccine failure of 1947 revisited: major intrasubtypic antigenic change can explain failure of vaccine in a post-World War II epidemic

The post-World War II epidemic of 1947 is notable for the total failure of a vaccine previously effective in the 1943-44 and 1944-45 seasons.” Proceedings of the National Academy of Sciences of the USA 2002

Two cases of exudative retina detachment and uveitis following H1N1 influenza vaccination

“Uveitis was a rare adverse event of vaccination. We met two cases of acute uveitis with exudative retinal detachment following vaccination of H1N1 influenza.” Chinese Medical Journal 2011

Vaccines without thiomersal: why so necessary, why so long coming?

“ The potential toxicity in children seems to be of much more concern to them than the hidden sensitising properties of thiomersal. In The Netherlands, unlike many other countries, the exposure to thiomersal from pharmaceutical sources has already been reduced. Replacement of thiomersal in all products should have a high priority in all countries.” Drugs 2011

What, in Fact, Is the Evidence That Vaccinating Healthcare Workers against Seasonal Influenza Protects Their Patients? A Critical Review

The present paper examined each of the arguments in favor of HCW influenza vaccination and showed that they are not supported by existing literature. The evidence base supporting vaccination is unsound and prejudiced.” International Journal of Family Medicine 2012


And here’s another good study using a true placebo and a 9 month follow up showing that flu shot not only doesn’t work, it makes kids more likely to get sick.

This study followed kids for nine months after they were randomly assigned to receive the fl
u vaccine or a placebo. The results showed that kids who received the flu vaccine were MORE likely to get sick during the next 9 months (with non-influenza respiratory illnesses). 

Interestingly, the study found higher flu antibody levels in the kids who received the vaccine, but “no statistically significant difference in the risk of confirmed seasonal influenza infection between recipients of TIV or placebo.” This means that the flu shot raised antibody levels but was not shown to actually protect kids against flu infection. And at the same time, the flu shot INCREASED the kids’ risk of non-flu respiratory illnesses. 

The study provides some hypotheses for why this may be the case. 

Interestingly, they didn’t look at any illnesses reported in the first 14 days after vaccination, which is the most likely time period for people to report feeling ill after a flu vaccine. If they had included those 14 days, the results would likely have looked even worse for the flu shot.

Interstitial Pneumonia Associated with the Influenza Vaccine: A Report of Two Cases. Internal Medicine 2017

“We encountered two cases of interstitial pneumonia that developed after vaccination during the 2014-2015 influenza season. Overall, nine cases, including the two presented here, have been recorded in PubMed and the Cochrane library. Interstitial pneumonia is rare; however, we found an increase in its incidence after 2009.”
