Protection from infection wanes over time. So boosters will offer extra protection and hopefully reduce the spread of the virus even further.
Exercise is still one of the best ways to boost longevity.
Life-extension therapies may be coming sooner than you think.
But the immune cells that vaccination spurs do last a long time.
The estimated lifetime costs of antiretroviral therapy for someone who acquires HIV at age 35 is $358,380.

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.

A growing body of research shows that nutrition, sleep, exercise and a host of other lifestyle choices can help optimize the immune system. But they are no substitute for life-saving vaccines.
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.
New discovery could help scientists develop more targeted drugs and vaccines.
Emergency medical technicians aid a COVID-19 patient at his home in Louisville, Kentucky. Like much of the U.S., Louisville is experiencing an uptick in COVID-19 patients requiring emergency transport to medical facilities.

Medications to treat COVID-19 are in no way a substitute for the vaccine. But under the right circumstances, some show great promise for helping patients.
People getting vaccinated may still have questions about COVID-19 vaccines, like why it takes two doses — and then two weeks — to take full effect.

A medical student answers questions he gets asked at a COVID-19 vaccine clinic: Efficacy versus real-world effectiveness, immune response and how the mRNA vaccines compare to vaccines already in wide use.
During pregnancy, the body’s specialized immune cells must learn to recognize the fetus as part of the self so that they don’t attack it.

How the immune system learns not to attack a developing fetus and placenta is important to understanding pregnancy and its common complications, like miscarriage.
Despite rampant misinformation, studies show that COVID-19 vaccines are safe for both the mom and baby.

A COVID-19 vaccine does not cause infertility – but it can protect you from the dangerous complications of contracting the virus.
Cancer and organ transplant patients, people with untreated HIV and people with other immunodeficiencies are at high risk of severe COVID-19 infection.

People with weakened immune systems are at a high risk of severe and prolonged COVID-19 infections. An extra vaccine dose can bolster protection.
Recovering from COVID and then getting vaccinated, known as hybrid immunity, is more potent than being infected or vaccinated alone.
Spending more time in nature may be associated with less fear of germs.
A fear of microbes, like germs, could be harming human health.
Vaccination has saved millions of lives throughout the course of history.

Vaccines have successfully curtailed viral diseases for decades. But as COVID-19 vaccination hesitancy shows, mistrust and misinformation continue to put lives at risk.
Our body clock has evolved over millions of years to help us survive.

Our immune system is controlled by our “body clock” – an intricate 24-hour system which controls how cells function.
People are likely to show compassion to those showing symptoms of illness or injury. Is that how our immune system evolved?
White blood cells dying.
The survival of the human body is a fine balancing act between cell growth and cell death. Understanding our cells’ complex “licence to die” could give us new ways to combat disease.
Invisible to the eye, the microbial life in the air around us can vary depending on our environment.

Observing the progression of an infection in real-time allows us to better understand how antibiotic resistance develops.
