A third dose has been shown to help in these cases. In one study, one-third of solid organ transplant patients who had a suboptimal response to two doses of the Pfizer or Moderna vaccines were able to develop an antibody response with a third dose. Those who are immunocompromised may wonder if the vaccine they received is successfully generating immunity in their body. A preliminary study that has not yet been peer-reviewed did find that a test that specifically targets the anti-spike antibodies the vaccines trigger may be helpful in determining whether the vaccine worked. But for now, the FDA does not recommend antibody tests to assess immunity.

The disappearance of the Mayan Empire is all the more mysterious because it happened not once, but twice. The earliest civilization that took root during the heart of antiquity prospered for hundreds upon hundreds of years, with innovations that rivaled those of Egypt. Unlike the Egyptians and Mesopotamians, however, the Mayans grew their population on the back of corn, beans, squash, and chiles, rather than wheat. Even so, they began building the first of their grand temples before they would vanish, but what was the cause of the end of this empire?

BALTIMORE – In a first-of-its-kind surgery, a 57-year-old patient with terminal heart disease received a successful transplant of a genetically-modified pig heart and is still doing well three days later. It was the only currently available option for the patient. The historic surgery was conducted by University of Maryland School of Medicine (UMSOM) faculty at the University of Maryland Medical Center (UMMC), together known as the University of Maryland Medicine.

Doctoral student Amir Haluts is researching the unusual and dangerous sex lives of golden orb-weaver spiders. Imagine a two-dimensional enclosed space, where a murderous female ruler sits in the center. Contestants are thrown into the ring, and they seem puny compared to her, but one of them manages to overcome his competitors to maneuver in behind her without her noticing, and wins the right to potentially mate with her. This could be the plot of a bloody reality show – or a Squid Game challenge – but it's actually the way of life of the golden orb-weaver spiders (Trichonephila), common in Africa, South America and the Far East.

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness. The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments. WHO will continue to provide updated information as soon as clinical findings become available.
