Myocarditis after BNT162b2 vaccination in Israeli adolescents.

Myocarditis cases reported after mRNA-Based COVID-19 vaccination in the US from December 2020 to August 2021.

A case-control study showed an increased risk of myocarditis after COVID-19 vaccination with a messenger RNA vaccine compared to an inactivated virus vaccine.

[Preprint] Risk of myocarditis following sequential COVID-19 vaccinations by age and sex.

Risks of myocarditis, pericarditis, and cardiac arrhythmias associated with COVID-19 vaccination vs. SARS-CoV-2 infection.

Case series with 139 adolescents and young adults with suspected myocarditis following mRNA vaccination showed most cases had a mild clinical course and rapid resolution of symptoms.

Heart-inflammation risk from Pfizer COVID vaccine is very low.

Large cohort study with over 2.5 million individuals showed the incidence of myocarditis after the Pfizer vaccine was 2.13 cases per 100,000 persons.

Study with over 5.1 million vaccinated individuals showed the incidence of myocarditis after the receipt of the Pfizer vaccine was low and more common after the second dose in young male recipients.

Large Observational study shows Pfizer Covid vaccine is mostly safe but is associated with increased risk of myocarditis, adenopathy, appendicitis, and herpes zoster.

In our latest paper from ISARIC4C we show that covid and flu together is a dangerous combination: 4x greater odds of needing a ventilator; 2x greater odds of dying. So we should test more widely for flu, and if you are offered a vaccine, please take it https://t.co/gI2GQnTRQH

Vitamin D Supplements for Prevention of Covid-19 or other Acute Respiratory Infections: a Phase 3 Randomized Controlled Trial (CORONAVIT) – medRxiv

Conteúdos relacionados:

M-A: Low vitamin D levels do not aggravate COVID-19 risk or death, and vitamin D supplementation does not improve outcomes in hospitalized patients with COVID-19.

In a Mendelian randomization study, researchers found no genetic evidence to support an association between Vitamin D levels and COVID-19 susceptibility, severity, or hospitalization.

Living systematic review: The evidence is insufficient to determine the benefits and harms of vitamin D supplementation as a treatment of COVID‐19.

RCT: Vitamin D3 does not improve outcomes in hospitalized patients with moderate to severe COVID-19

CORONAVIT trial (vitamin D supplements for Covid prevention) results are negative, but the implications are narrow and must not be misinterpreted.https://t.co/mnmDeOJFak
This was a well done trial in many ways. Here's what is reasonable to conclude from it & what isn't:
