A German researcher thinks he knows what has caused some people to develop blood clots after receiving coronavirus vaccines. University of Greifswald hematologist Andreas Greinacher believes the reaction is linked to EDTA, a preservative found in the AstraZeneca vaccine. The AstraZeneca vaccine contains more than 1,000 proteins that have been derived from human proteins —
Mucormycosis: hyphae of the fungus Mucor, from the paranasal sinus of a patient with diabetes mellitus. Public health officials report a rare black fungus infection, called mucormycosis, which is increasingly seen in vulnerable patients, including those with COVID-19 disease. India faces a global health crisis as the number of severe acute respiratory syndrome coronavirus 2
Vaccines are often described as one of the greatest public health interventions in recent history, based on the profound effect that they have had in decreasing global morbidity and mortality. Immunizations currently prevent 2-3 million deaths each year, and aside from sanitation and clean drinking water, they are credited as having the largest impact on population growth
In the early months of the COVID-19 pandemic, healthcare workers analyzing test results began noticing something strange: patients who had already recovered from COVID-19 would sometimes inexplicably test positive on a PCR test weeks or even months later. Although people can catch COVID-19 for a second time, this did not appear to be the case
Pfizer and BioNTech’s coronavirus reduces the risk of getting sick from COVID-19 by five- to 30-fold for fully immunized people, two new studies show. In one report, just 0.4 percent of healthcare workers in Israel who received both shots of the COVID-19 immunization later tested positive compared to 7.2 percent of unvaccinated employees. This means healthcare workers who
Moderna said its COVID-19 vaccine is 96 percent effective among youths aged 12 to 17, according to the results of its first clinical trials. Two-thirds of the 3,235 participants in trials in the United States received the vaccine and one-third were given a placebo. The study “showed vaccine efficacy against COVID-19 of 96%; mRNA-1273 was generally well
Norwegian and Danish researchers published a register study in BMJ of over 281,000 people who have received the AstraZeneca vaccine. – The study confirms previous findings from OUS and internationally. The registry study finds 11 additional cases of venous thrombosis among 100,000 vaccinated. The article that follows people who have received the AstraZeneca vaccine in
A new study is drawing the most detailed picture yet of SARS-CoV-2 infection in the lung, revealing mechanisms that result in lethal COVID-19, and may explain long-term complications and show how COVID-19 differs from other infectious diseases. Led by researchers at Columbia University Vagelos College of Physicians and Surgeons and Herbert Irving Comprehensive Cancer Center, the study found
In a major shot in the arm for the Pfizer-BioNTech COVID-19 vaccine, researchers have reported in two studies that it is highly effective in protecting against severe COVID-19 infections caused by the variants first reported in the UK and South Africa. In a study published in the New England Journal of Medicine on May 5, researchers analysed
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus is highly contagious and causes lymphocytopenia, but the underlying mechanisms are poorly understood. In this paper published on Nature fresearchers of Laboratory of Cell Engineering, Institute of Biotechnology, Beijing, China demonstrate that heterotypic cell-in-cell structures with lymphocytes inside multinucleate syncytia are prevalent in the lung tissues
