Pfizer and moderna to investigate their own vaccines

Why is Big Pharma investigating their own covid vaccines for
myocarditis side effects if the vaccines were already supposedly
tested and proven safe and effective?
Both Pfizer and Moderna have announced that they will be
undertaking studies to determine the longer term risks of Myocarditis
(an inflammatory condition of the heart which can lead to death)
for people who have been injected with the mRNA based covid
vaccines.  The decision comes after the release of multiple medical
studies which show a correlation and causation between the vaccines
and an exponential increase in heart problems, specifically among
men 40 years old and younger.  Only a year ago the link between covid
vaccinations and myocarditis was widely denied. 
Studies also show that myocarditis risk increases with the number
of boosters a person has taken.
Before the year 2020, the average vaccine was tested and re-tested
by pharmaceutical companies and the FDA for 10 to 15 years before
it could be released to the public. This was done not only because
testing is a complex process with a lot of red tape involved, but
also because it is the only way to discover any long term
side-effects that might be associated with a particular immunization
product.  If you read any medical journal or scientific outline on
vaccine development published before 2020, they all agree that
long term testing is necessary for public safety.
Suddenly, after 2020 and the advent of public activism against the
covid mandates, a host of medical "professionals" and bureaucrats
began arguing that the mRNA vaccines do not need the same lengthy
testing time frame because government funding allowed for everything
to be accomplished much faster.  This is a lie.
What really happened?  Governments fast tracked approval using
national emergency measures allowing Big Pharma to skip necessary
tests and trials.  Example:  Pfizer representatives recently admitted
under oath that they never tested the covid vaccine to see
if it actually prevented transmission of the virus.  They simply
claimed that it did without verification.  And governments began
trying to enforce vaccine requirements on the populace based on
the false claim that vaccination stops the spread.

Mainstream media "fact checkers" insist that the covid vaccines were
"initially effective" in preventing transmission of the original
strains of the virus.  There is no concrete evidence to confirm this.
In fact, covid cases of the original variants began to plunge in the
US and in other countries before the vaccines were widely
distributed. This is a fact, and the incredible drop in cases was
likely due to an increase in natural immunity within the population.
Some government and Big Pharma funded scientists also argue that
mRNA technology as a whole has been tested for many years. This
is a dishonest misdirection.  The technology and concept might have
been tested in various experiments for years, but the specific covid
vaccines were not, and this matters.  Any scientist that says this
claim is a foundation for safety confirmation for the vaccines should
be ashamed of themselves.  
Studies which take natural immunity and asymptomatic reactions into
account when determining vaccine efficacy are highly limited. There
is no way to know if a person survived covid or avoided infection
because they were vaccinated, or because they already had the virus,
experienced minor symptoms or no symptoms, and developed natural
immunity.  Government paid virologists and scientists don't seem to
care about testing the distinction.  What we do know from various
studies is that natural immunity is far superior in every way to mRNA
vaccination.
The dangers of releasing a pharmaceutical cocktail for mass
consumption or even forced mass consumption without long term
study cannot be overstated.  The bottom line?  Given the current
information, no one knows for sure what will happen in terms
of vaccine effects over a long timeline (several years). Pharma
companies don't know and governments don't know (if we take
their production claims for the vaccines as accurate).
In all likelihood, Pfizer and Moderna are trying to get out ahead
of burgeoning side effects with their own studies as a means to spin
or mitigate bad press in the future.  The chances of these studies
providing honest data driven assessments are low.
It's been less than two years since widespread distribution of the
covid vaccines and we are already seeing signs of negative health
issues through myocarditis and blood clotting disorders. One has
to wonder what further terrible developments will unfold for
vaccinated people in another two years.
