An immunologist explains that you get some protection from the first dose of the mRNA vaccines but you need two to build up strong immunity, particularly to newer coronavirus variants.
During a raging pandemic it is obviously worthwhile to use hand sanitisers, particularly when we are unable to wash our hands. But we should minimise their use when cases drop.
COVID-19 prevention measures are at odds with guidelines for healthy development of children’s immune systems. The result may be a cluster of youth with more allergies, asthma and autoimmune disease.
You need a new shot every year because current flu vaccines provide limited and temporary protection. But researchers’ new strategy could mean a one-and-done influenza vaccine is on the way.
With vaccine shortages looming, experts are debating whether it is important to receive two doses or whether it’s better to give one dose to more people and give a second when the supply is better.
With vaccines forthcoming for most Americans, many groups, including expectant mothers, are wondering if the vaccine is safe for them and their babies. A physician-scientist explains.
The development of multiple vaccines against the virus that causes COVID-19 has been hailed as the breakthrough of 2020. But there were many more supporting discoveries that made this possible.
The side effects of new SARS-CoV-2 vaccines are a result of immune system activation. While uncomfortable, they are both normal and expected. They are a sign that the vaccine is working.
There is now a third vaccine that prevents COVID-19 infections. It isn’t quite as effective as the other two vaccines but it has advantages that may make it the frontrunner.
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?
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.
