Intranasal administration with a single dose of a chimpanzee adenovirus-vectored SARS-CoV-2 vaccine induces potent immune responses.
Rhesus macaques that are vaccinated against SARS-CoV-2 are protected from severe disease and probably transmit very little virus when infected with SARS-CoV-2 one year later.
A heterologous vaccine regimen consisting of a first dose of the AstraZeneca vaccine and a second dose of the Pfizer vaccine induces a stronger immune response than a regimen consisting of two doses of the AstraZeneca vaccine.
Accumulating data suggest that SARS-CoV-2 vaccination of pregnant and lactating people is safe and beneficial for both mother and child.
Recently I had a false positive PCR result for SARS-CoV-2. To confirm that I was not infected, I did an assay for viral antibodies in my blood using a rapid, at home, lateral flow assay. In this video I explain how the assay works and what my results mean.
by Gertrud U. Rey There are currently 315 therapeutic drugs and 210 vaccine candidates in development to treat or prevent SARS-CoV-2 infection. Many of these vaccines are designed to be administered by injection into the muscle. Intramuscular injection of a vaccine antigen typically induces a systemic (serum) immune response that involves the action of IgM and IgG …
