Here the authors analyze data from COVAIL trial participants receiving an mRNA second COVID-19 vaccine boost and show that, while neutralizing antibody titer is correlated with Omicron COVID-19 risk, the correlation is weak in naïve individuals compared to previously infected ones. _ Bo Zhang ...

Negative controls were collected from eight individuals (age range: 20–55 and median: 47.5 years of age, 7 females and 1 male) having never received a COVID-positive test. Enrollment was completed prior to October 1st 2020. According to the Institut National de Santé Publique du Québec (...
Chinese scientists and their U.S. counterparts have developed two cocktail antibodies against COVID-19 that may deliver a one-two punch to infections caused by the prevalent Omicron variant. Researchers from the University of Science and Technology of China, the Chinese Academy of Sciences and the...

Monoclonal antibodies have proven to be an important therapeutic option in the ongoing battle against COVID-19.
Peter Doherty Institute for Infection and Immunity (Doherty Institute), the University of Melbourne and Walter and Eliza Hall Institute of Medical Research, the study published on Sunday compared different antibody responses to the virus in blood serum from 41 people who had recovered from COVID-19...
Two and a half years into the COVID-19 pandemic, we have gained many insights into the human antibody response to the causative SARS-CoV-2 virus. In this Review, we summarize key observations of humoral immune responses in people with COVID-19, discuss k
When someone who has had a mild case of COVID is vaccinated, the antibody level in their blood doubles compared to an unvaccinated person who has been infected by the virus. Their antibodies are also better able to prevent spike-ACE-2 interaction. "But what's even more interesting," said ...
It is not strictly true thatnobody who hasn't alreadyhad COVID-19 has immunity to the disease. We do have some capacity in our bodies to protect ourselves. Also, our immune systems can learn during theinfectionand clear thevirusfrom our body. This is essentially the mainstay of current t...
