Previously SARS-CoV-2 infected, if unvaccinated: reinfection by SARS-CoV-2 is likely, study finds

Throughout the COVID-19 pandemic, there has been much uncertainty about how long immunity lasts after an unvaccinated person is infected with SARS-CoV-2. Now a team of scientists led by faculty at Yale School of Public Health and the University of North Carolina at Charlotte have an answer: Strong protection following natural infection is short-lived. “Reinfection

COVID-19 Vaccines guarantee protection to non immune family members too

Risk of COVID-19 in families with two to five members. An interesting new study published in the journal JAMA Internal Medicine examines the risk of coronavirus disease 2019 (COVID-19) to a susceptible individual who is part of a family with COVID-19 immunity. Study: Association Between Risk of COVID-19 Infection in Nonimmune Individuals and COVID-19 Immunity in Their Family

Unvaccinated Americans are at higher risk from COVID-19 but express less concern than vaccinated adults

Americans who are not vaccinated against COVID-19 are far more likely than vaccinated people to contract the coronavirus and to be hospitalized and die from it, according to the Centers for Disease Control and Prevention. Even so, a recent Pew Research Center survey finds they are less likely to be concerned about the health effects of the virus and to

Anti-Platelet Factor 4 Antibodies Causing VITT do not Cross-React with SARS-CoV-2 Spike Protein

In Blood, Greinacher and colleagues examine humoral responses in vaccine-induced thrombotic thrombocytopenia (VITT) and COVID-19 to determine whether these illnesses are immunologically distinct or represent a disease continuum. At a surface level, vaccine-induced thrombotic thrombocytopenia (VITT), a recently described complication of adenoviral-based COVID-19 vaccines, and COVID-19 have much in common. Both illnesses owe their origins to severe

Convalescent plasma is “futile” as COVID-19 treatment for critically ill patients, trial published on JAMA shows

In the earliest days of the COVID-19 pandemic, the medical community turned to a century-old treatment: Take blood from recovered patients and give it to the sick. The hypothesis was that components in the so-called “convalescent plasma” that fought off the disease once could do it again, something that has worked in other diseases, such
