European press reports earlier indicated that the EU's pharma regulator is preparing to expedite approval of the AstraZeneca-Oxford vaccine, even as the FDA expands its investigation into the COVID-19 vaccine's Phase 3 trials (after a patient was reportedly seriously sickened in the UK, though AZ insists that illness had nothing to do with the trial).

As the WHO, Bill Gates, Dr. Fauci and the global health-care establishment work with their allies in the press to try and convince as many people as possible to agree to take a COVID-19 vaccine once one is approved, more alarming reports are emerging in the mainstream press about issues with the 'Phase 3' trials.

CNBC reported Thursday morning that several patients involved in trials involving Moderna's vaccine candidate and the Pfizer-BioNTech vaccine candidate have experienced serious side effects, including "shaking so hard he cracked a tooth after taking the second dose."

As bad as they were, the symptoms typically dissipated within a day or two, and four out of the five subjects interviewed by CNBC said they felt the struggle was "worth it" to gain protection from COVID-19. Then again, the symptoms certaintly sound serious.

Luke Hutchison woke up in the middle of the night with chills and a fever after taking the Covid-19 booster shot in Moderna's vaccine trial. Another coronavirus vaccine trial participant, testing Pfizer's candidate, similarly woke up with chills, shaking so hard he cracked a tooth after taking the second dose.

High fever, body aches, bad headaches and exhaustion are just some of the symptoms five participants in two of the leading coronavirus vaccine trials say they felt after receiving the shots.

In interviews, all five participants - three in Moderna's study and two in Pfizer's late-stage trials  - said they think the discomfort is worth it to protect themselves against the coronavirus. Four of them asked not to be identified, but CNBC reviewed documentation that verified their participation in the trials.

While the symptoms were uncomfortable, and at times intense, they often went away after a day, sometimes sooner, according to three participants in the Moderna trial and one in Pfizer's as well as a person close to another participant in Moderna's trial.
