Seaweed Extract Stops COVID in Early Testing
As scientists hunt for alternatives for people who can't access vaccines for COVID-19, they are searching underwater in unexpected places to study the therapeutic potential of edible marine algae.
Conclusions: The novel SARS-CoV-2 vaccine upregulates the immune system to produce an adaptive immune response. The SARS-CoV-2 vaccine may potentially be associated with increased risk of rejection in those with ocular surface transplants.
Abstract: As the understanding of COVID-19 infection becomes better, it is being recognized as a complex multisystem pathology rather than just affecting the lungs. Several ocular findings have been documented by researchers in individuals infected with COVID-19, and ocular symptoms may even be the first presenting feature of COVID-19 infection in 2.26% individuals. Several countries have started vaccination with inactivated or live vaccines to combat this pandemic, and varied side effects have been reported after vaccination. Few cases of herpes zoster have previously been reported in elderly patients with comorbiditi...
Conclusions: To the best of our knowledge, this case of full-thickness graft rejection after the Moderna SARS-CoV-2 mRNA vaccination is the first to be reported worldwide. The temporal relationship between vaccination and subsequent rejection is highly suggestive of causation due to the short interval (3 days) between vaccination and rejection and the lack of other inciting factors in an otherwise healthy graft. Patients with corneal transplants who plan to take the COVID-19 vaccinations should be counseled on symptoms and closely monitored, and an individualized plan should be made in discussion with the ophthalmologist.
Although there are many hypotheses for the age-related difference in the severity of COVID-19, differences in innate, adaptive and heterologous immunity, together with differences in endothelial and clotting function, are the most likely mechanisms underlying the marked age gradient. Children have a faster and stronger innate immune response to SARS-CoV-2, especially in the nasal mucosa, which rapidly controls the virus. In contrast, adults can have an overactive, dysregulated and less effective innate response that leads to uncontrolled pro-inflammatory cytokine production and tissue injury. More recent exposure to other ...
This report describes a case of aseptic meningitis 3 weeks after administration of the second dose of Comirnaty. The patient recovered with conservative and symptomatic care after 5 days of admission. Surveillance of rare adverse events, including aseptic meningitis, and their management should be prompt and appropriate.
It is too soon to know, scientists say, but mild initial illness may not signal reduced risk.
