Myocarditis was mentioned in the report from Pfizer in early 2021, why it took so long to check this out when it was written it’s a special interest?

Why is this not made public from Pfizer? People are dying from the mRNA covid-19 vaccine from Pfizer, how is it about the mRNA Covid-19 vaccine from Moderna?
It started already more than a year ago and now they making some investigation, why?
