The Food and Drug Administration (FDA) has limited the authorized use of the Johnson & Johnson vaccine due to rare blood clots.

The vaccine was found to cause potentially fatal blood clots.

A new study suggests recipients of Moderna’s COVID-19 vaccine may be more likely to suffer repeated infections, perhaps indefinitely.

Peer-reviewed study findings "raise concerns regarding vaccine-induced undetected severe cardiovascular side-effects and underscore the already established causal relationship between vaccines and myocarditis, a frequent cause of unexpected cardiac arrest in young individuals."

A recent case report about a man who received an mRNA-based COVID-19 vaccine suggests that taking the vaccine “may trigger immune-mediated hepatitis,” researchers wrote.

The natural immunity provided by COVID-19 infection in unvaccinated adults is on par with protection conferred from vaccines against reinfection with or hospitalization from the virus, a new study reveals.

Judicial Watch today announced it received 466 pages of records from the U.S. Department of Health and Human Services (HHS) regarding biodistribution studies and related data for the COVID-19 vaccines that show a key component of the vaccines developed by Pfizer/BioNTech, lipid nanoparticles (LNPs), were found outside the injection site, mainly the liver, adrenal glands, spleen and ovaries of test animals, eight to 48 hours after injection.

Some viruses, after initial infection, remain latent in the body for a lifetime and may reactivate to cause infection again or a different condition.

Pfizer on Tuesday said results of Phase 2 clinical trials of its experimental Lyme disease vaccine delivered “positive” results, including among pediatric trial participants.

"Antibodies produced by vaccinated and boosted people may not stop omicron SARS-CoV-2 strain from entering cells as well as it stops original virus," say Johns Hopkins researchers.
