People from getting infected in the first place, you want to maintain a sufficient number of neutralizing antibodies, and to do that, you might immediate to provide boosters shots on some kind of semi-regular basis points. but that doesn't mean those individuals won't have t-cells and b-cells that are program to attack this virus that will give them residual virus. there's different correlates of immunity that we should look at right now, i'm talking about levels of neutralizing antibodies which protect against getting protected in the first place. >> we're seeing obviously a real success here...

At a Glance The immune systems of more than 95% of people who recovered from COVID-19 had durable memories of the virus up to eight months after infection. The results provide hope that people receiving SARS-CoV-2 vaccines will develop similar lasting immune memories after vaccination. Colorized scanning electron micrograph of a cell, isolated from a patient sample, that is heavily infected with SARS-CoV-2 virus particles (red). NIAID Integrated Research Facility, Fort Detrick, Maryland After people recover from infection with a virus, the immune system retains a memory of it. Immune cells an...

Wikimedia / The Atlantic For much of 2020, the world pinned its collective post-pandemic plans on a single, glimmering end point: the arrival of an effective COVID-19 vaccine. The resounding refrain of “when I’m vaccinated” has long conjured images of people shedding their masks, hugging their friends, and returning to a semblance of normalcy. And now some vaccinated people are doing exactly that. In recent weeks, I’ve heard dozens of stories from friends, family members, and co-workers about vaccinees who are immediately dropping their guards after their shots, in some cases discardi...

Although Parkinson’s disease affects around 1%-2% of people over the age of 65, there is currently no cure. And by the time it is diagnosed – typically by identifying problems with movement, such as slower movements and tremors – the changes in the brain it causes are irreversible. So being able to identify Parkinson’s earlier will be important in finding ways to prevent and cure the disease. In our latest study, my colleagues and I have identified changes in blood that occur years before a Parkinson’s diagnosis. This could lead to earlier diagnosis of the disease. The causes of Pa...

The Atlantic The virus is evolving, but the antibodies that fight it can change, too. Getty / Mark Harris To locate some of the world’s most superpowered cells, look no further than the human immune system. The mission of these hometown heroes is threefold: Memorize the features of dangerous microbes that breach the body’s barriers. Launch an attack to bring them to heel. Then squirrel away intel to quash future assaults. The immune system is comprehensive, capable of dueling with just about every microbe it meets. It’s archival, ace at memorizing the details of its victories and defeat...
