Primary COVID-19 Infection Protects Against Potential Reinfection?

Primary COVID-19 Infection Protects Against Potential Reinfection?

These study outcomes suggest reinfection is relatively rare in patients who recover from COVID-19. In addition, natural immunity against SARS-CoV-2 persists for at least one year and offers similar protection to that reported by vaccines.   These data were obtained from cases infected with the original virus. For now, we do not know if it also

Efficacy of Mass Vaccination with Pfizer/BioNTech against COVID-19 in Israel

We need to know how effective vaccines are by population subgroup outside the controlled setting of a clinical trial.  Israel was one of the first countries to deploy a nationwide mass vaccination strategy. This is why it results ideal to compare its results against clinical trial results.  All subjects receiving the BNT162b2 mRNA Covid-19 Vaccine

Asymptomatic Patients: The Key to Understand the Prevalence of the COVID-19 Pandemic

This study recently published in JAMA showed that asymptomatic individuals infected with COVID-19 account for more than half of all instances of disease transmission. This finding is key to direct resources in the right direction to manage the pandemic until safe and effective vaccines are available and widely used. Severe acute respiratory syndrome coronavirus 2

Safety and Efficacy of the Pfizer-BioNTech Vaccine Against COVID-19

The NEJM has published the efficacy of the COVID-19 vaccine developed by Pfizer and BioNTech, featuring slight differences in the age of enrollment and endpoint definitions compared with other vaccines. Similarly to Moderna‘s, this vaccine is composed of a lipid nanoparticle with modified RNA that encodes a spike glycoprotein covering the surface, modified by two

Natural History of Asymptomatic COVID-19 Infection

Information on the natural history of asymptomatic infection with the new coronavirus (COVID-19) remains scarce. We are just beginning to understand what happens with patients with severe disease. The outbreak of COVID-19 on the cruise ship Diamond Princess provided a unique opportunity to study contacts and patients with asymptomatic infection within a closed population. This

Efficacy of Remdesivir against COVID-19

This final report published in NEJM about the efficacy of remdesivir against COVID-19 infection vs placebo showed its superiority though only in soft end points, which does not seem to modify the course of this pandemic. Multiple drugs initially promising have been shown ineffective against the new virus. The case of hydroxychloroquine resulted paradigmatic: not

Long-Term Cardiovascular Effects of COVID-19

In many places worldwide, the worst part of the pandemic is still to come. Meanwhile, in other areas, the number of cases is rising again. In this context, the long-term effects of COVID-19 are starting to show. Many believe this is not a current issue, but it will definitely be a problem in the future.

LATAM: Information on the Impact of the Pandemic with a Focus on MI

There are several studies from all corners of the world (China, Europe, USA) presenting data on the impact of COVID19 on interventional cardiology in general, and on MI in particular. What is new about this study is that it presents data on LATAM and that it has been published in an international magazine.  Seldom do

When and How Could Dexamethasone Be Useful in a COVID-19 Infection?

More details have emerged on the group of COVID-19 patients who received dexamethasone in the RECOVERY trial. These data, published as a preliminary report in the New England Journal of Medicine (NEJM), suggest that dexamethasone could reduce mortality in cases when infection effects are mainly derived from immunopathological elements in patients requiring mechanical ventilation or
