Antibodies and Covid-19

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

Original Research: Seroprevalence of Rubella IgG Antibodies in Women of Child Bearing Age attending a hospital in South-western State in West Africa

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

Seroprevalence of covid antibodies via infection.

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

Antibodies play a key role in the fight against viruses

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

(Non)seroconversion after Covid infection.

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

September 25, 2021. Monoclonal Antibodies May Reduce Hospitalizations in High Risk Ambulatory Patients with COVID-19

This article (this article is a preprint and has not been peer reviewed yet) shows a quasi-experimental observational cohort study using target trial emulation and

Pfizer vaccine effectiveness in pregnant women.

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

The Meaning of Antibodies #lols

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

Great COVID-fighting news recently.

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

Infection after vaccination dramatically increases antibodies.

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

Prior severe covid infection yields higher antibodies than those with milder disease.

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

mRNA vaccination in patients with multiple schlerosis and anti-CD20 therapy.

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

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

Study suggests booster shots probably not needed - to end Pandemic, we do!

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

CD8 T-Cells vs antibodies.

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,

Seroprevalence in the US, antibodies from infection vs vaccinations.

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,

Another reason for people with prior infection to be vaccinated!

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,

The challenge of keeping antibodies up in the midst of runaway variants.

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,
