An overview of severe covid vaccine adverse events.
Please note: SPR only covers vaccine-related issues that are of global importance. To study verified case reports of vaccine-related injuries and deaths, see Covid Vaccine Injuries (18+).
A) Guillain-Barré syndrome (GBS)
Guillain-Barré syndrome (GBS) is an auto-immune neurological disease causing muscle weakness and paralysis, usually starting in the feet and hands, with about 20% of people still unable to walk at 6 months, and a fatality rate of about 5% (due to respiratory failure). Back in 1976, the US swine flu vaccination campaign was stopped due to an increased risk of GBS.
In the UK, more than 400 cases of post-vaccination GBS have already been reported (due to under-reporting, the true figure is likely higher); in the US, there may already be several thousand cases of covid vaccine-related GBS. As with many other covid vaccine adverse events, GBS may affect people at low risk of severe covid (e.g. students), or even people who already had covid.

B) Menstrual disorders, miscarriages, and birth defects
US authorities have argued that covid vaccines “appear to be completely safe for pregnant women” (NIH) and “are thought not to be a risk to lactating people or their breastfeeding babies” (CDC). However, the US VAERS system counts already 1,500 post-vaccination miscarriages, and it has been known since March that covid mRNA vaccines, or the coronavirus spike protein they produce, may get into breast milk and sicken or kill a baby. In addition, by August 2021, more than 13,000 British women have reported post-vaccination menstrual disorders, such as excessive bleeding, and some first cases of post-vaccination birth defects have also been reported.
C) Heart muscle inflammation and heart attacks
Back in March, SPR first covered a “murky wave of heart attacks” and an increase in post-vaccination all-cause mortality in Israel. In early June, Israel confirmed that mRNA vaccines may cause heart inflammation and heart attacks, especially in young people (in whom it is more unusual). On June 11, the US CDC announced an “emergency meeting” to discuss post-vaccination heart inflammation in young people (young males, in particular).
In both Israel and the United States, post-vaccination mortality in young adults has reached record levels. In Italy, ten days after the Pfizer vaccine was authorized for children, a 12-year-old tennis prodigy died at home due to a “sudden illness”, with no medical cause given.
D) Blood clots and strokes
Blood clots, cerebral venous thrombosis and pulmonary embolism continue to be major vaccine adverse events, especially after adenovector covid vaccines (AstraZeneca, Johnson&Johnson). Several countries have already stopped the use of adenovector vaccines altogether or in non-senior citizens. Most recently, Italy took this decision, too, after several young women died.
Life-threatening blood clots may also affect athletes, such as, most recently, a US elite runner and a professional basketball player in Germany (who required emergency brain surgery). A 44-year-old BBC moderator died due to blood clots and cerebral bleeding caused by the AstraZeneca vaccine. Several cases of leg amputations due to vaccine-induced blood clots have also been reported.
Of note, the risk of blood clots may significantly increase during air travel. British Airways confirmed the death of three of their pilots, aged 30 to 55, shortly after vaccination with AstraZeneca.
E) Severe skin reactions
Severe skin reactions have been reported quite frequently after covid vaccinations. Such reactions may be due to an immune response affecting micro blood vessels in the skin (eryhtema multiforme), or due to a vaccine-induced bleeding disorder (thrombotic thrombocytopenic purpura).
F) Eye disorders and blindness
Covid vaccines may lead to bleeding in the eyes and, in severe cases, to blindness. In the UK, several hundred cases of post-vaccination blindness have been reported. In the US, about 1,500 reports to the VAERS system mentioned ‘blindness’.
G) Bell’s palsy
Bell’s palsy is a unilateral facial paralysis that may last for up to six months. By August 2021, about 4,000 cases of post-vaccination Bell’s palsy had been reported to the US VAERS system, but the real number of cases is likely in the tens of thousands.

Reports of post-vaccination shingles (i.e. herpes zoster reactivation) have been quite frequent: by August 2021, about 8,000 cases of post-vaccination shingles had been reported to the US VAERS system (true figure may be close to 100,000). Herpes zoster reactivation may occur due to temporary vaccine-induced immune suppression; about 20% of shingles patients develop a type of long-lasting neurological pain called postherpetic neuralgia (PHN).
New onset of tinnitus is a rather frequently reported adverse event of covid vaccines: by August 2021, more than 10,000 cases of post-vaccination tinnitus had been reported to the US VAERS system.
Of note, the Johnson & Johnson covid vaccine clinical trial registered already six cases of ‘non-severe’ tinnitus within 28 days of vaccination, but the US Food and Drug Administration (FDA) later ruled they were ‘unrelated to the shot’.
In general, tinnitus may be caused by neuro-inflammation or blood vessel disorders, such as endothelial dysfunction, which may explain how covid vaccines, which produce the coronavirus spike protein, can trigger temporary or even permanent tinnitus.
K) Anaphylactic shock
Covid vaccinations may lead to a potentially life-threatening anaphylactic (allergic) shock. People affected by an anaphylactic shock may collapse shortly after vaccination.
