Sure it's the same vaccine. But, the CDC, FDA and the WHO won't authorize a vaccine until adequate trials have been completed to show that it is statistically safe. Taking vaccines without any trial is ... horrendously dangerous. Which, Trump was suggesting he wanted to do, and the Right - Wing cheered him on for it while Left Wing gawked in disbelief at the zealousness for Trumpism. Once the trials were completed, we trusted it.
I find it laughable anyone who cries out crisis over the deaths of vaccine that those same people were the same ones saying "COVID is not serious." When the fatality rate was recorded at 4% of all cases. Whereas of the 187.2 million people who have been vaccinated, only 6,000 have died as of July 19th.
That's .0018% of doses received result in death. You're more likely to get cancer from an x-ray (I looked it up.) So please, spare the fake outrage.
