І знову атака росіянців на мирний Київ цієї ночі. І знову влучання у мирний будинок, де люди просто жили, а в момент влучання - спали чи знаходилися в себе вдома... Це варварство, це тероризм, який вони

COVID-19 and Ireland – Part 25 ~Part 1~ In a recent article in this series we saw that there were several ways in which a case of covid-19 could be diagnosed by detecting the presence of the virus

It is another opportunity to share our research work here. This research work is similar to the one I shared not long ago here but this time, the research focused on another Southwestern state in west

Latest data on how many people have antibody evidence of previous COVID infection. Overall, it went from 34 to 58% in just two months (Dec-Feb). By age group in February: 0-11: 75% (Up 31 points in just

In my country in recent weeks there has been a significant increase in the number of cases of Covid-19 infections, despite the fact that millions of people have already received the vaccine, which suggests

Dr Ryan Cole - Natural Immunity From Covid Is The Best Defense ▶️ 3Speak

"Seroconversion" is the technical term for when the humoral immune system begins producing antibodies subsequent to an infection or vaccination. There's a paper in the journal "Emerging

This article (this article is a preprint and has not been peer reviewed yet) shows a quasi-experimental observational cohort study using target trial emulation and causal inference methodology in pre-and

This was mostly for pre-Delta as the study ran from December 20th to June 3rd in Israel. Estimated vaccine effectiveness was 96% against infection, 97% against symptomatic infection, 89% against

Antibodies are very important for our immune system in getting over viral and bacterial diseases. We make non-specific IgM Antibodies (Ab) initially then specific IgG Ab later. Once we make IgG we are

The FDA now has fully authorized the Pfizer vaccine, which clears the way for big employers (eg the US military, other government orgs) to make it mandatory. Many such large organizations have already

We have previously seen that those who were vaccinated after infection have much higher antibody levels than those who only got the vaccine or infection. This study shows that it works the other way around,

We have previously seen that those with prior covid have, on average, some neutralizing antibodies against the delta variant at six months but not one year. This study done in Thailand looks specifically

This is a detailed study of the immune response to vaccination for one specific group of immunocompromised people, those taking anti-CD20 monoclonal antibodies. This study was done in people with MS, but

The research team that previously discovered spike-resistant plasma cells in the bone marrow of people who recovered from the novel coronavirus has now taken cell samples from the lymph nodes of the vaccinated

The research group that previously found anti-spike plasma cells in the bone marrow of people recovered from covid has now taken samples of cells from the lymph nodes of people who have been vaccinated

Although some people had hoped that CD8 T-cells would last longer after infection than antibodies, this study, which tested 24 people about 9 months after covid, found that nearly everyone had low or no

I give you two maps. On the left, we have a map showing frequency of anti-nucleocapsid antibodies, which can only come from infection, not vaccination. On the right, we have a map showing vaccine coverage.

Link to study: This is a study that I wrote about when it was available as a preprint. I think it's worth revisiting now that the full paper has been published, as it provides a little more data about

As my antibodies slowly decline, I have been thinking about long-term efficacy of the RNA vaccines against the B.1.351 (SA) variant. As one of the trial guinea pigs, I’m eight months out from my second
