Parker: We don't know a lot about this yet. There is only a little bit of data, from laboratory studies in which they took antibodies from people who have been vaccinated and looked to see if they could block the virus in a dish. The preliminary results suggest omicron is less sensitive...
Every year scientists take their best stab at developing a flu vaccine. The fluvirusmutates every year, so they can never be 100 percent certain which strain will hit. According to Dr. Bradley, the live-attenuated (intranasal) flu vaccine is actually best at protecting against the flu, even...
Unlike CRISPR/Cas9, the CRISPR/Cas12a system does not require assistance from RNA or other proteins to process pre-crRNA into mature crRNA (Fig.1b) (Zaidi et al.2017). As a result, Cas12a can achieve target cleavage without the need for tracrRNA. Additionally, Cas12a recognizes alternative ...
toldJAMAEditor in Chief Howard Bauchner, MD, in a February 3podcast. Regardless of the platform on which the vaccine is based, Fauci said, “you still have a fixed immunogen and a virus that’s changing. Sooner or later, you’re going to get a mutant...
As a virus infects people, it can mutate as it makes copies of itself. Some mutations can be harmful to a virus, causing it to die out. Others can offer an advantage and help it spread. “Not every mutation is created equal,” said Mary Petrone, who studies infectious diseases at Yal...

With the intensification of the greenhouse effect, a series of natural phenomena, such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will in
While the most powerful nations looked inward, four non-governmental global health organizations began making plans for a life-or-death struggle against a virus that would know no boundaries. What followed was a steady, almost inexorable shift in power from the overwhelmed governments to a group ...
"The SARS-CoV-2 virus has the potential to mutate further," Godsil adds, so there is a chance this fall will bring an entirely new strain. Since July, scientists have been monitoring a highly mutated variant called BA.2.86, aka“Pirola," but recent data suggests it may not be as contag...
This means the immune system should have recognized and neutralized the same SARS-CoV-2 variant if challenged within six to eight months (if an infection occurred, it should have resulted in mild to no symptoms). But what about when the virus mutates?
