It has the potential to do lots of harm. For example, certain doctors believe it will cross the blood/brain barrier. In animal trials, apparently the animals developed spongiform encephalopathy which gave rise to neurodegenerative diseases like ALS, Alzheimers, and Parkinson's. Former Pfizer executive and researcher Michael Yeadon says Pfizer never did a reproductive analysis to see what this does to the reproductive system (highly unethical). Dr. Peter McCullough says radiology depts have had to revamp the way mammograms are done on vaccinated women due to swelling of the breast tissue. A number of doctors with outstanding credentials believe the spike protein may give rise to autoimmune disorders and blood cancers, over time. These medical issues will not necessarily be associated with the vaccines at first because they will occur at a later time, several years out.
You really need to educate yourself before posting stupid things like this on the internet. Start here: https://www.bitchute.com/video/wZWBGx6czySq/ The danger of the vaccines is not necessarily an upfront issue. A Canadian researcher found that the spike protein in the vaccines is traveling to people's vital organs, bone marrow, and ovaries. According to Robert Malone, who invented mRNA vaccine technology, this is very dangerous because he believes the spike protein is biologically active (contrary to what the medical bureaucracy is telling people.
With regard to the mRNA vaccines (Moderna, Pfizer), it is estimated that it would take a year-and-a-half for humans to develop the brain diseases that killed the animals in the animal models. The animals allegedly developed spongiform encephalopathy (mad cow disease) and then other fatal neurological diseases like Alzheimers and ALS. There also has been no testing to determine infertility, or birth defects in the offspring of vaccine recipients.

He became suspicious of the medical bureaucracy because he knows that off-patent meds like Hydroxychloroquine and Ivermectin worked well to treat Covid and they were clearly suppressed in favor of dangerous "vaccines." Since he is a practicing clinician, his knowledge comes through experience. He relies on Michael Yeadon and others who have done a deep dive into the "vaccines" as well. Hell, Dr. Robert Malone who invented mRNA vaccine technology, says these vaxxes now appear very dangerous. Look at his Twitter feed before it gets taken down.
