“None of the healthy blood donors had any antibodies against either virus. These findings suggest that betacoronaviruses can induce immune responses against one another, generating neutralizing antibodies and/or cross-reactive antibodies against each other.”

“The use of mRNA vaccine technology allows rapid scaling of vaccine production and facilitates modification if the virus mutates significantly. Two mRNA vaccines (Pfizer-BioNTech and Moderna) are currently authorized for use in the United States.”

“SARS-CoV-2, the virus that causes COVID-19, is a type of coronavirus, a family of viruses that also causes the common cold. Based on new findings, having a recent infection with the coronaviruses that cause the common cold and pneumonia, commonly referred to as endemic coronaviruses (eCoV), may reduce COVID-19 severity.”

“Tools, companies, and resources mentioned OpenAI - AI research and deployment company behind widely used GPT systems and developer tools; its science case study describes GPT-5 helping Unutmaz's lab resolve a long-standing immunology question.”

“In a podcast I recorded with Dr. Dale Bredesen he discussed the role of the bacteria P. gingivalis, herpes virus, and other infectious agents play in promoting Alzheimer's disease.”
