The germinal centre (GC) response is critical for the generation of affinity-matured plasma
cells and memory B cells capable of mediating long-term protective immunity …

Neutralizing antibodies can block infection, clear pathogens, and are essential to provide
long-term immunity. Since the onset of the pandemic, SARS-CoV-2 neutralizing antibodies …

Although SARS-CoV-2 infects the upper respiratory tract, we know little about the amount,
type, and kinetics of antibodies (Ab) generated in the oral cavity in response to COVID-19 …

Background Although the BNT162b2 COVID-19 vaccine is known to induce IgG neutralizing
antibodies in serum protecting against COVID-19, it has not been studied in detail whether it …

As the number of individuals vaccinated against SARS-CoV-2 rises worldwide, population-
level data regarding the vaccines' ability to reduce infection are being generated …

Sterilizing immunity after vaccination is desirable to prevent the spread of infection from
vaccinees, which can be especially dangerous in hospital settings while managing frail …

Humoral responses to COVID-19 vaccines in people living with HIV (PLWH) remain
incompletely characterized. We measured circulating antibodies against the SARS-CoV-2 …

Emerging SARS-CoV-2 variants of concern (VOCs) pose a threat to human immunity
induced by natural infection and vaccination. We assessed the recognition of three VOCs (B …

Background Although the serological antibody responses induced by SARS-CoV-2 vaccines
are well characterized, little is known about their ability to elicit mucosal immunity. Objectives …

Specific memory B cells and antibodies are a reliable read-out of vaccine efficacy. We
analysed these biomarkers after one and two doses of BNT162b2 vaccine. The second dose …
