Booster Shots Causing More Injuries Than Previously Thought, Israeli Survey Shows

    More Israelis are experiencing injuries and reactions following COVID-19 booster shots than the country’s passive reporting system indicates, according to a survey conducted by the Israeli Ministry of Health. What do the data tell us about safety signals and underreporting?

    TRUTH LIVES on at

    More Israelis are experiencing injuries and reactions following COVID-19 booster shots than the country’s passive reporting system indicates, according to a survey conducted by the Israeli Ministry of Health (MOH).

    The MOH conducted an active survey of booster shot recipients to collect data on adverse events associated with booster doses, then compared the survey data to the data available from the country’s passive reporting system. 

    The survey concluded Israel’s passive reporting system was grossly underreporting adverse events.

    The data from the Israeli survey could provide some insight into the extent of the underreporting occurring in the U.S.

    It also could corroborate safety signals the Centers for Disease Control and Prevention (CDC) is ignoring.



    What the survey found

    The MOH survey was extensive in its breadth but limited in size.

    More than 4,000 people were selected for the questionnaire. Of those, 2,049 were considered reliable reports.

    The questionnaire was conducted between 21-30 days from the date the booster was administered.

    The survey identified more than 40 different categories of vaccine reactions for both men and women. It also questioned a subset of women about their menstrual cycle.

    Four of the 40 categories are immediately relevant to the booster rollout in the U.S. and any subsequent boosters the CDC might authorize moving forward.

    The four categories are:

    1. Hospitalizations

    Six of the 2,049 (.29%) respondents were admitted to hospital following the booster shot. That number, though seemingly insignificant, carries more import when extrapolated to the millions of booster doses that have been administered:

    • Israel: 4.5 million booster doses administered = 13,000 hospitalizations
    • U.S.: 92 million booster doses administered = 270,000 hospitalizations.

    2. Exacerbation of pre-existing disease

    Six different categories of reported “chronic morbidities” (pre-existing diseases) were identified. These were the proportions of respondents in each category that reported a worsening of their disease after receiving a booster:

    • Heart disease = 5.4%.
    • Hypertension = 6.3%.
    • Lung disease = 7.0%.
    • Diabetes = 9.3%.
    • Anxiety disorder or depression = 26.4%.
    • Autoimmune disease = 24.2%.

    3. Neurological side effects

    A percentage of respondents (4.5%) reported a neurological adverse event.

    Ten different categories of neurological side effects were reported, including tingling sensations, Bell’s Palsy, blurred vision, convulsions and involuntary movements.

    Also, 3.9% of respondents reported an allergic reaction following the booster dose (rash, difficulty breathing, face/throat swelling), though no instances of anaphylaxis were reported.

    4. Menstrual cycle irregularities

    While the U.S. government-run Vaccine Adverse Event Reporting System (VAERS) does not track information specific to a woman’s menstrual cycle, the volume of reported irregularities from the Israeli survey bears note.

    Of the 615 female respondents who were under the age of 54, 59 (9.6%) reported menstrual irregularities. These women were surveyed in a follow-up interview. Within this subgroup, according to the survey, more than 88% of women reported a regular menstrual cycle before the booster dose.

    However, after the booster dose:

    • 31.1% sought medical treatment for menstrual irregularities.
    • 9.1% received medication for the adverse reaction.
    • 39.0% suffered similar side effects after previous COVID vaccinations. More than two-thirds of women reported that these initial conditions waned in the five-month interval between the primary dose series and booster dose, but the conditions returned after the booster was administered. About half the women reported their adverse event was ongoing during the seven- to 12-week window of the follow-up.

    Due to the overwhelming number of anecdotal reports of menstrual irregularities here in the U.S., the National Institutes of Health in September 2021 awarded Boston University a $1.67 million grant to study the effects of COVID vaccines on menstruation. The results are expected to be published in spring of 2022.

    In addition to the reactions listed above, the MOH survey also found reports of injection-site reactions and general reactions.

    The problem of underreporting

    If reporting vaccine adverse events is the key to identifying safety signals, then underreporting creates an epidemic of another sort.

    Josh Guetzkow, Ph.D., a law professor at the Hebrew University of Jerusalem, analyzed the Israeli survey, levying a heavy-handed indictment of the safety data reported by Israel’s MOH and the vaccine mandates that followed.

    While he noted that the differences between Israeli and U.S. reporting systems do not lend themselves to a direct correlation, Guetzkow was able to make some connections.

    Using the active survey data, Guetzkow established an approximate underreporting factor (URF) for adverse events within the Israeli population (URF = 1 means all instances of an adverse event were captured):

    • Loss of consciousness URF = 1,700.
    • Difficulty breathing URF = 48,000.
    • Seizures URF = 6,500.
    • Bell’s Palsy URF = 6,000.
    • Blurred/disturbed vision URF = 4,000.

    How does the URF in Israel’s passive reporting system compare with underreporting by VAERS in the U.S.?

    As stated above, the differences between the two reporting systems prevent direct correlation. The MOH does not use the international classification system, MedDRA, for its reporting.

    However, Guetzkow was able to generate some URF estimates of several serious conditions based on similarities in the two reporting systems.

    Here’s what he found:

    • Seizures/convulsions VAERS URF = 731 (Total expected cases = 177,632).
    • Hospitalizations VAERS URF = 126 (Total expected cases = 266,488).
    • Bell’s Palsy VAERS URF = 3,034 (Total expected cases = 488,488).
    • Shingles (herpes zoster) VAERS URF = 401 (Total expected cases = 133,200).

    Even if these numbers are exaggerated by 50%, they should still be setting off safety signals within the CDC, which would, in turn, prompt further investigation.

    In the absence of active, independent survey data in the U.S., which one would think vital in the face of a global push for an experimental vaccine, such extrapolation of data from other countries is the best we can do.
