Significant decline of neutralising antibodies to monkeypox virus during the first month after vaccination
New research shows that even in men who receive two doses of mpox vaccine intradermally, their level of antibodies to the virus falls to low or zero within the first few months if they have not received a previous smallpox vaccine.

Gut bacteria make neurotransmitters to shape the newborn immune system
Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.

Researchers show viral infections pose early heart risks
Myocarditis is often triggered by the body’s immune response to a viral infection, but a new study shows that the virus itself creates potentially dangerous conditions in the heart before inflammation sets in.
