Comparison of a Micro-Neutralization Test with the Rapid Fluorescent Focus Inhibition Test for Measuring Rabies Virus Neutralizing Antibodies

Tropical Medicine and Infectious Disease, 2017
The rapid fluorescent focus inhibition test (RFFIT) is routinely used in the United States to measure rabies virus neutralizing antibodies (rVNA). RFFIT has a long history of reproducible and reliable results. The test has been modified over the years to

SARS-CoV-2 delta (B.1.617.2) spike protein adjuvanted with Alum-3M-052 enhances antibody production and neutralization ability

Frontiers in Public Health, 2023
BackgroundOptimizing adjuvant is one of the critical methods to improve the vaccine. 3M-052, a novel TLR7/8 agonist which was designed for slow dissemination at the injection site, has a potential as adjuvant, but its performance as a vaccine adjuvant ...

DIFFERENTIAL CROSS-NEUTRALIZATION OF DENGUE IMMUNE SERA AGAINST ZIKA VIRUS

International Journal of Infectious Diseases, 2023
Intro: Zika virus (ZIKV) is transmitted to humans primarily via the bites of infected female Aedes aegypti and Aedes albopictus. The mosquitoes are also the vector for the transmission of dengue viruses. Malaysia is a dengue hyperendemic country. To date,

NEUTRALIZATION OF INFLUENZA A VIRUS BY HUMAN SERUM [PDF]

Journal of Experimental Medicine, 1941
A linear relationship exists between the quantity of human serum used and the quantity of influenza A virus neutralized. By means of this relationship it is possible to determine the maximum quantity of virus which a given human serum can neutralize. This quantity, the neutralizing capacity, is a fixed value and, unlike the serum dilution end point, is

Delayed neutralizing antibody response in the acute phase correlates with severe progression of COVID-19

Scientific Reports, 2021
Adaptive immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) dynamics remain largely unknown. The neutralizing antibody (NAb) levels in patients with coronavirus disease 2019 (COVID-19) are helpful for understanding the pathology ...

Vaccination and Omicron BA.1/BA.2 Convalescence Enhance Systemic but Not Mucosal Immunity against BA.4/5

Microbiology Spectrum, 2023
Rising breakthrough infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.4/5 led to the performance of various studies investigating systemic immunity and neutralizing antibodies in sera, but mucosal immunity remains ...

Neutralizing Antibodies in COVID-19 Serum from Tatarstan, Russia

International Journal of Molecular Sciences, 2023
The severity of COVID-19 is a result of the complex interplay between various branches of the immune system. However, our understanding of the role of neutralizing antibodies and the activation of cellular immune response in COVID-19 pathogenesis remains limited.

Booster COVID-19 vaccination against the SARS-CoV-2 Omicron variant: A systematic review

Human Vaccines & Immunotherapeutics, 2022
There is a wealth of data suggesting that the effectiveness of existing vaccines against the Omicron variant, the most mutated SARS-CoV-2 variant to date, has been substantially reduced if only primary vaccination is administered.
