Preprint: Enhanced Fusogenicity of BA.4, BA.5 and BA.2.12.1

“We found that the new Omicron subvariants BA.4/5 and BA.2.12.1 were more resistant to neutralization by mRNA-vaccinated and boosted health care worker sera and Omicron-BA.1-wave patient sera than were the BA.1 and BA.2 variants.”...More...

Spain: Fully boosted healthcare worker reinfected with SARs-CoV-2 after just 20 days

A fully boosted 31-year-old Spanish woman has contracted two different SARS-CoV-2 variants within three weeks. The 20-day gap between infections is the shortest known....More...

Bill Gates: “Omicron, is a type of vaccine…”

Microsoft co-founder Bill Gates was recently recorded as saying “Sadly, the virus itself, particularly, the variant called omicron, is a type of vaccine, that is, it creates both B-cell and T-cell immunity, and it’s done a better job getting out to the world population than we have with vaccines.”...More...

Preprint: Intranasal delivery of SARS-CoV-2 Spike protein is sufficient to cause olfactory damage

We hypothesize that SARS-CoV-2 spike (S) protein is sufficient to cause olfactory damage and olfactory dysfunction.

Using an adult zebrafish model, we report that intranasally delivered SARS-CoV-2 S RBD mostly binds to the non-sensory epithelium of the olfactory organ and causes severe olfactory histopathology characterized by loss of cilia, hemorrhages and edema....More...
