Observing the progression of an infection in real-time allows us to better understand how antibiotic resistance develops.
It’s not a bad sign if you feel fine after your COVID-19 shot.

It's normal for different people to mount stronger or weaker immune responses to a vaccine, but post-shot side effects won't tell you which you are.
Hand sanitisers are everywhere.
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.
Children’s early interactions with their environment are essential for the immune systems to learn to differentiate between safe versus dangerous disease-causing microbes.
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.
Our study revealed breastfed babies had twice the number of regulatory T cells.
Until now, researchers haven’t quite known why the immune systems of breastfed babies are better equipped.
Children in the study seemed to display a very strong "innate" immune response.
Our research could be important for developing more effective vaccines in the future.

We mapped the genes of B cells to better understand why some develop immunity and others don't.
Wouldn’t it be nice if one shot could protect you for life?

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.
Cambridge study finds blood markers that could help predict, very early in the disease, who will get severe COVID.
Health care workers wait in line for vaccinations at a site in Los Angeles.

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.
I am a physician, and I just got my first shot of the Pfizer COVID-19 vaccine.
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 number one scientific breakthrough for 2020: multiple vaccines to prevent COVID-19.

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.
A little bit of post-injection soreness is completely normal.

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.
Several new studies show our immune responses to the virus can last at least eight or nine months, and probably longer.
Now there is a third possible vaccine for fighting the COVID-19 pandemic.

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.
Working out strengthens more than just your muscles – it strengthens your immune system, too.

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.
In autoimmune diseases, circulating antibodies destroy an individual’s own tissues.

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.
