Mansanguan et al.: "Cardiovascular Manifestation of the BNT162b2 mRNA COVID-19 Vaccine in Adolescents"; students who received 2nd dose of Pfizer mRNA injection; Cardiovascular manifestations in 29%

by Paul Alexander

n=301, most common cardiovascular signs & symptoms were tachycardia (7.64%), shortness of breath (6.64%), palpitation (4.32%), chest pain (4.32%) & hypertension (3.99%).

The reality is that when most reports do not tell you (in the media) the vaccine status of those who suddenly died, then we have to conclude they are vaccinated. Alike the 95 young doctors in Canada who have died suddenly and we know they have been vaccinated, there is this putrid cover-up and dis-information and deceit by the media and governments and the medical establishment. This is actually harming those who received the vaccine. We simply seek the truth, honesty for informed decision-making.

Key study often overlooked and told us clearly that the mRNA vaccines are a major concern in terms of cardiovascular complications for young persons. Reports tend to indicate affliction mainly to young males but we have research from Basel, Switzerland now questioning this and raising the real concern that females are as afflicted if not more than males.


‘13 participants were lost to follow-up, leaving 301 participants for analysis.

The most common cardiovascular signs and symptoms were tachycardia (7.64%), shortness of breath (6.64%), palpitation (4.32%), chest pain (4.32%), and hypertension (3.99%). One participant could have more than one sign and/or symptom. Seven participants (2.33%) exhibited at least one elevated cardiac biomarker or positive lab assessments. Cardiovascular manifestations were found in 29.24% of patients, ranging from tachycardia or palpitation to myopericarditis.

Myopericarditis was confirmed in one patient after vaccination. Two patients had suspected pericarditis and four patients had suspected subclinical myocarditis. In conclusion, Cardiovascular manifestation in adolescents after BNT162b2 mRNA COVID-19 vaccination included tachycardia, palpitation, and myopericarditis. The clinical presentation of myopericarditis after vaccination was usually mild and temporary, with all cases fully recovering within 14 days. Hence, adolescents receiving mRNA vaccines should be monitored for cardiovascular side effects.
