The companies have not submitted the booster for FDA approval yet. Neither the companies nor the government recommend booster shots yet, until their safety and effectiveness can be fully explored. A booster shot of the COVID-19 vaccine made by Pfizer and BioNTech strongly extends protection, a new study from the companies shows, and they are developing a vaccine targeted directly at the Delta variant, which first arose in India. The companies say they have demonstrated that a third dose of their vaccine, given six months after the second, increases neutralizing antibodies five to tenfold ag...

View Comments A booster shot of the COVID-19 vaccine made by Pfizer and BioNTech strongly extends protection, a new study from the companies shows, and they are developing a vaccine targeted directly at the Delta variant, which first arose in India. The companies say they have demonstrated that a third dose of their vaccine, given six months after the second, increases neutralizing antibodies five to tenfold against the original virus and the so-called Beta variant, which was first identified in South Africa. The booster was also found to be safe. They plan soon to publish this data and sub...

It is little wonder that some TB vaccine researchers suffer from a rare syndrome that understandably threatens their mental health. Symptoms include frustration, impatience, irritability, seemingly inexplicable rage, and in the least resilient, despair. It is called VJS or vaccine jealousy syndrome** - in 99% of cases associated with the sudden appearance and out of kilter funding of, (in an astoundingly short 12 months), Cpvid-19 vaccines. Never ones to miss an opportunity, even though they carry the research begging bowl, the TB crew have started leveraging the remarkable scientific advanc...

SARS-CoV-2 infection induces polyfunctional antibodies that can destroy infected cells Drawing on epidemiological field studies and the FrenchCOVID hospital cohort coordinated by Inserm, teams from the Institut Pasteur, the CNRS and the Vaccine Research Institute (VRI, Inserm/University Paris-Est Créteil) studied the antibodies induced in individuals with asymptomatic or symptomatic SARS-CoV-2 infection. The scientists demonstrated that infection induces polyfunctional antibodies. Beyond neutralization, these antibodies can activate NK (natural killer) cells or the complement system, leading...
