A new mouse study reports an experimental vaccine that produced rapid protection and antibodies that lasted up to 18 months. Researchers say a booster strengthened and extended immune responses and plan manufacturing steps before human trials.
Mpox may be spreading quietly in Nigeria
A study in Nigeria tested archived blood from healthy adults and found signs of hidden mpox exposure. Some people had old smallpox antibodies and a small number showed recent immune responses without symptoms, suggesting low-level virus circulation.
Engineered antibodies could block cytomegalovirus
A research team created changed antibodies that stop human cytomegalovirus from disabling immune responses. Lab tests show the antibodies reduce virus spread, but researchers say more testing is needed before they can be used in people.
