Two pharma companies have announced early COVID-19 vaccine trial results with over 90 per cent effectiveness. What does that mean for getting back to normal?

Anti-complement drugs have shown promise in treating COVID in several small trials. Larger trials are now underway.
Are antibodies that attack a patient’s own organs contributing to severe forms of COVID-19? A new study suggests specific antibody tests that may reveal the answer.
Any COVID-19 vaccine is likely to be given first to higher risk groups before it is given to children. But we still need vaccines that are safe and effective for them too.
Reports of reinfection shouldn’t be cause for alarm. If we gather the right data, they can teach us a lot about the immune response.
Man-made chemical disrupt the activities of most human genes. What effect does this have on human health and how should regulators respond?
Vaccines work by teaching your immune system about new viruses. Your immune cells are very clever – they will remember what they learnt, and protect you if you encounter that virus in the future.
Patients suffering from severe COVID-19 may be experiencing a rogue antibody response similar to that seen in autoimmune diseases. The findings offer new approaches for COVID-19 therapy.
Our first exposure to a pathogen, either naturally or via vaccination, can affect how our immune system responds in the future to the same or similar pathogens.
The president and first lady Melania Trump have both tested positive for the coronavirus. Here’s what the physicians and scientists know about the best treatments for the disease it causes.
Older coronavirus patients face grimmer outlooks. A virologist explains the aging-related changes in how immune systems work that are to blame.
Antibodies are great for neutralizing viruses. But they are big and bulky. Antibody engineers are now creating smaller synthetic antibody-like molecules that may be better for fighting COVID-19.
Several vaccines are in Phase 3 trials. So when will we know whether any of these will protect against COVID-19?
Many of us don’t get an adequate amount of nutrients.
Not all vaccines will work so well in all people. That’s why we need large-scale clinical trials to test candidate vaccines in thousands of people.
Three new studies show corticosteroids can reduce deaths in critically ill COVID-19 patients. But what about other patients?
The immune system is trained to destroy viruses, even when they carry therapeutic cargo as is the case in gene therapy. Now researchers have figured out how to dial down the immune response.
If antibody levels drop dramatically after an infection, what does that mean for immunity? An expert explains how B and T cells contribute to immunity and why antibodies don’t tell the full story.
Scientists were not surprised by reports on coronavirus reinfection; the lack of symptoms on reinfection is encouraging.
Researchers discover clues to the origin of inflammatory bowel disease and a possible strategy for treatment.
