Viral Vector News and Research

RSS

Viral Vector is a type of virus used in cancer therapy. The virus is changed in the laboratory and cannot cause disease. Viral vectors may produce tumor antigens (proteins found on a tumor cell) to stimulate an antitumor immune response in the body. Viral vectors may also be used to carry genes that can change cancer cells back to normal cells.

Exploring vaccine-induced cellular immunity against SARS-CoV-2 Omicron variant

In a new study, researchers determined CD8+ and CD4+ T cell responses against the SARS-CoV-2 Omicron variant in 51 individuals vaccinated with the messenger ribonucleic acid (mRNA)-based Pfizer and adenovirus vector-based Johnson & Johnson vaccines.

Researchers identify common side effects of three COVID-19 vaccines

COVID-19 vaccines remain the best tool in the pandemic toolbox against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). But they are not perfect; reports have surfaced of mild to severe side effects after vaccination. A new study from researchers in the Lampe & Company GmbH & Co. KG compared the severity of adverse events from each coronavirus vaccine.
