Vaccine News and Research

RSS

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

COVID-19 virus can infect heart cells in a lab dish, study shows

A new study shows that SARS-CoV-2, the virus that causes COVID-19 (coronavirus), can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be directly infected by the virus.

Researchers identify a new subset of cells involved in immune response against hepatitis B

For the first time, researchers at The Westmead Institute for Medical Research have identified and described a new and unique subset of human cells that are involved in the immune response against hepatitis B (HBV) infection. The discovery could help develop new treatments for HBV and inform future vaccine design.

Study shows coronavirus does not induce cross-protective immune antibodies

According to researchers, patients infected with severe acute respiratory syndrome coronavirus (SARS-CoV) or SARS-CoV-2 generate antibodies that adhere to the other coronavirus; however, the cross-reactive antibodies are not actually cross-protective, as far as cell-culture experiments are concerned.
