A 100% French nasal vaccine against SARS-CoV-2 to move into the clinical phase in 2022

In contrast to intramuscular vaccines, only nasal vaccines are able to block the virus in the nose by inducing local immunity in the nasal mucosa, i.e. the portal of entry and multiplication of the virus.

COVID mRNA vaccines display weakened immune response with age and diminish over time, according to new study

Researchers from Simon Fraser University in Canada decided to investigate the magnitude of immunity in mRNA vaccines for COVID-19.

Quantification of salivary IgG and IgA against SARS-CoV-2

Salivary antibody levels are many fold lower than found in blood serum, Immunoglobulin G (IgG) in the saliva is mainly sourced from leakage from the gingival surface and Immunoglobulin A (IgA) from mucosal membranes.
