More than two years after Operation Warp Speed began, Children's Health Defense (CHD) commissioned John Zogby Strategies to conduct two surveys (see here and here) about attitudes and the overall health of American adults.

Key highlights from the survey of 1,038 adults

The survey found that 67% of respondents received one or more COVID-19 vaccines, while 33% are unvaccinated. Furthermore, among those vaccinated, 6% received one dose, 28% received two doses, 21% received three doses, and 12% took four or more.

Of those receiving a COVID-19 vaccine, 15% say they've been diagnosed by a medical practitioner with a new condition within a matter of weeks to several months after taking the vaccine.

"The fact that the Centers for Disease Control and Prevention (CDC) reports more than 232 million Americans ages 18-65 have taken at least one dose of the COVID-19 vaccine, and 15% of those surveyed report a newly diagnosed condition is concerning and needs further study," said Children's Health Defense (CHD) executive director Laura Bono. "The mRNA vaccine technology is new and clinical trials naturally have no long-term data. CHD believes this survey points to the need for further study."

Other key demographics of newly diagnosed medical conditions after COVID-19 vaccines show:
  • 17% of those receiving two doses
  • 13% of respondents had three shots
  • 30% of those ages 18-29
  • 23% of those ages 30-49
  • 6% of those ages 50-64
  • 4% of those older than 65
  • 7% of whites
  • 21% of African-Americans
  • 32% of Hispanics
  • 15% of liberals
  • 14% of moderates
  • 8% of conservatives



Comment: Is this more evidence to confirm what was suspected a year ago, that the younger you are, the stronger the immune system is and therefore the greater the damage caused by a vaccine reaction?

A follow-up question provided a list of medical conditions and asked diagnosed respondents to "select all that apply." Among those who were medically diagnosed with a new condition within a matter of weeks to several months, the top five cited conditions were:
  • 21% blood clots
  • 19% heart attack
  • 18% liver damage
  • 17% leg clots/lung clots
  • 15% stroke
Overall, 67% reported that getting the vaccine was a good decision, 24% were neutral and 10% regret it.

Survey participants were then asked if someone they personally know had been medically diagnosed with a new medical condition within the same time frame. Overall, 26% reported yes, while 63% reported no.

Looking at age cohorts:
  • 34% of those ages 18-29 say they know someone who was diagnosed, as did
  • 30% of those ages 30-49,
  • 21% of those ages 50-64,
  • and 18% of those older than 65
Again, respondents were offered the same list of conditions and asked to "select all that apply." The top five cited conditions were:****
  • 28 % blood clots
  • 20% stroke
  • 19% autoimmune
  • 16% lung clots
  • 15% heart attack

Key highlights from the survey of 829 adults ages 18-49


Among those under age 50 - 62% report receiving a COVID-19 vaccine vs. 38% who have had none.

Among those receiving any COVID-19 vaccine, almost one quarter — 22% — report being medically diagnosed within a matter of weeks to several months after taking a shot.

The top five cited new conditions include:
  • 21% autoimmune
  • 20% blood clots
  • 19% stroke/lung clots
  • 17% liver damage/leg clots/heart attack
  • 15% disrupted menstrual cycle/Guillain-Barré/Bell's palsy
Regarding describing the conditions, 47% report mild, 43% report serious and 10% report severe/still recovering.

Describing their experience with taking one or more COVID-19 vaccines, 58% report it was a good decision, 28% are neutral and 14% regret it.

Finally, 30% of those ages 18-49 report knowing someone else who has been medically diagnosed within a matter of weeks to several months after taking a COVID-19 vaccine.

The top five cited medically diagnosed conditions of the person known by those under age 50 are:
  • 30% blood clots
  • 23% stroke
  • 20% autoimmune
  • 18% leg clots/lung clots
  • 17% heart attack
In other findings:

Regarding trust in the government to handle future pandemics among the all-adults survey — 23% say it has increased, 34% say it has decreased, 32% say it has remained the same, the rest were unsure.

The surveys included 1,038 American adults of all ages (MOE +/- 3.1) and 829 18-49-year-olds (MOE +/- 3.5) Both polls were fielded July 22-24, and data sets were pre-stratified and weighted to be representative of their respective populations. Error margins are higher for subgroups.
