People with HIV need to take daily medication to keep the virus at bay. A study has found that a new treatment combination could boost immunity and control virus levels even after stopping medication.

It’s unclear whether the patients were already predisposed to these diseases, or the infection unmasked a process that had already begun. Or perhaps the infection triggered a completely new illness.
People with weakened immune systems are at a high risk of severe and prolonged COVID-19 infections. An extra vaccine dose can bolster protection.
If you’ve already had the coronavirus and recovered, you might be tempted to give the vaccine a pass. A scientist explains why the shot offers the best protection against future infection.
Our study found lower levels of one type of immune cell – which may even be seen years before a person develops the disease.
Until now, researchers haven’t quite known why the immune systems of breastfed babies are better equipped.
Long-term protection will depend on the ‘memory response’ developed by our immune systems – and the initial signs are promising.
Antibody levels naturally fade – the key question is whether infected people sustain adequate levels of T cells and B cells.
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.
Older coronavirus patients face grimmer outlooks. A virologist explains the aging-related changes in how immune systems work that are to blame.
This is just one person. Is he the exception? Is he the rule? We don’t know yet for sure. But reinfection is definitely possible.
Some people’s blood can mount an immune response against SARS-CoV-2, even if those blood samples were taken from before the COVID-19 pandemic started.
It’s hard to discuss COVID without referring to white blood cells. Here is a primer on the two you need to know about.
If immunity is short-lived, we will be in an ongoing cycle of endless reinfection.
Our research has found a way of switching immune system cells from attacking to protecting.
Just focusing on spike proteins might not offer the complete immunity.
Immunity to COVID-19 may be complicated. Here are the promises and pitfalls of antibody tests.
The prizes are among the country’s most prestigious accolades for science-related achievements. This year marks their 20th anniversary.
The cornerstone of our adaptive immune system is the ability to remember the various infections we have encountered. Quite literally, if it doesn’t kill you, it makes your immune system stronger.
Anyone who’s had the flu can attest that it makes them feel horrible. But why? What is going on inside the body that brings such pain and malaise? An immunologist explains.
