Thrombocytopenia is a condition in which there is a lower-than-normal number of platelets in the blood. It may result in easy bruising and excessive bleeding from wounds or bleeding in mucous membranes and other tissues.
A study has revealed that adenovirus vector and mRNA-COVID-19 vaccines are associated with an increased risk of thromboembolism and thrombocytopenia.
A new study published on the preprint server medRxiv* presents an analysis of the differences between recorded vaccination side effects vs. early COVID-19 symptoms. The researchers focused on four vaccines, namely, Pfizer-BioNTech (PB) mRNA (BNT162b2) vaccine, based on messenger ribonucleic acid encoding the viral spike protein; the Moderna mRNA (mRNA-1273) vaccine; the Oxford-AstraZeneca (O-AZ) adenovirus-vectored vaccine; and the Janssen adenovirus-vectored Ad26.COV2.S).
Now, a new systematic review has been published in the journal Animals that focuses on the clinical symptoms in felines diagnosed with SARS-CoV-2 worldwide.
Researchers in Germany have provided evidence that a booster shot of a messenger RNA (mRNA)-based coronavirus disease 2019 (COVID-19) vaccine following prime immunization with AstraZeneca’s adenoviral vector-based vaccine is sufficient to achieve high levels of neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
A McMaster University team of researchers recently discovered how, exactly, the COVID-19 vaccines that use adenovirus vectors trigger a rare but sometimes fatal blood clotting reaction called vaccine-induced immune thrombotic thrombocytopenia or VITT.
New research has shown that early testing for blood clots in patients who had received the AstraZeneca/Oxford vaccine led to them being treated successfully, highlighting the need for heightened awareness of the risk among doctors.
A new study, released as a preprint on the medRxiv* server, indicates that pregnant women are more likely to develop severe disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
Vivid photos of the red "COVID arm" rash and reports of facial swelling in patients who have received dermatological fillers after Pfizer-BioNTech or Moderna vaccination for COVID-19 may increase patients' concerns about mRNA vaccine side effects and contribute to vaccine hesitancy.
Healthcare professionals and public health authorities have a central role in discussing vaccination against COVID-19 with their patients.
A new study, which was conducted by Vishala Mishra and Joseph P. Dexter at Madras Medical College, Chennai, India, suggests that the infamous pause in the administration of the Johnson & Johnson (J&J)/Janssen COVID-19 vaccine, advised by the FDA, has left doubt about the veracity of vaccine safety claims. This is a development that may have engendered vaccine hesitancy in a segment of the population.
A recent article published in the journal Frontiers in Tropical Diseases assessed the threat of emerging zoonotic and vector-borne tropical diseases.
Even as a host of vaccines have been rolled out to counter the coronavirus disease 2019 (COVID-19) pandemic, some serious adverse effects have been reported, in the form of thrombocytopenia. A new study in the journal Vaccine reports the results of an evaluation of reported cases of this condition, using data from the Vaccine Adverse Event Reporting System (VAERS).
A team of researchers has conducted a systematic review to identify laboratory factors that can predict the risk of severe and critical COVID-19 as well as associated mortality rates. The team – from institutions in India and the USA – recently published their findings in the Journal of Clinical Medicine Research.
Among the devastating complications of severe or critical coronavirus disease 2019 (COVID-19), clot formation ranks high in the adverse impact it creates. An important question is whether SARS-CoV-2-spike-based vaccines also cause such coagulopathies. A new study, released as a preprint on the medRxiv* server, examines this risk for the first time.
Now, a new report in the Journal of Thrombosis and Hemostasis reveals that timely diagnosis and treatment of this condition may prevent further morbidity and mortality, and enable the vaccine to be used widely with confidence.
New research published in BMJ confirmed evidence of blood clotting finding a small risk after receiving one Oxford-AstraZeneca ChAdOx1-S severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine.
Thus, the need to stratify the risk of severe or critical disease in patients presenting with SARS-CoV-2 infection remains a crying necessity. A new preprint research paper posted to the medRxiv server discusses the relationship between severe disease and pre-existing susceptibility to clots and other diseases of the cardiovascular system.
A new case report, detailed in Annals of Emergency Medicine, is the first known case of a patient with VITT (vaccine-induced thrombotic thrombocytopenia) treated with a heparin alternative following the Centers for Disease Control and Prevention (CDC) guidance.
The National Comprehensive Cancer Network announced today the publication of new NCCN Guidelines for Patients: Anemia and Neutropenia, Low Red and White Blood Cell Counts funded by the NCCN Foundation and endorsed by The Leukemia and Lymphoma Society (LLS).
Posts are showing up all over social media tying Covid-19 vaccinations to shingles and other painful skin disorders.
