An article published in npj Aging reveals that natural production of auto-antibodies increases with age, and that infection by SARS-CoV-2 can exacerbate production of auto-antibodies relating to auto-immune diseases, helping to explain why aging increases the chances of developing severe COVID-19. The study also discovered some of the factors that associate the severe form of the disease with blood clotting disorders such as thrombosis.
"These findings open the door to a better [...]

Investigadores brasileños compararon datos referentes a la respuesta inmunológica inducida por la infección natural y por las vacunas e identificaron qué factores son claves para el desarrollo de una inmunidad duradera. Estos resultados pueden orientar la búsqueda de nuevas vacunas y tratamientos antivirales.
Al comparar datos referentes a la respuesta inmunitaria resultante de una infección natural causada por el dengue con los de la [...]

By comparing data for the immune response to natural infection by dengue virus to data for activation of the immune system by dengue vaccines, researchers at the University of São Paulo (USP) have identified molecular markers that could be [...]

La vacuna Butantan-Dengue (Butantan-DV) es una vacuna tetravalente, viva, atenuada, de dosis única y en investigación contra la enfermedad del dengue, pero se necesitan datos sobre su eficacia general.
En un ensayo doble ciego de fase 3 en curso en Brasil, asignamos aleatoriamente a los participantes para recibir Butantan-DV o placebo, con estratificación según la edad (2 a 6 años, 7 a 17 años y 18 a 59 años); Está previsto un [...]

By comparing data for the immune response to natural infection by dengue virus to data for activation of the immune system by dengue vaccines, researchers at the University of São Paulo (USP) have identified molecular markers that could be used in the development of novel vaccines and treatments for dengue.
They also reiterated the efficacy of two vaccines already available on the market: Q-Denga, manufactured by Takeda Pharma (Japan) and now being distributed by the national health [...]

Ao comparar dados relativos à resposta imune resultante de uma infecção natural por dengue com os da ativação imunológica decorrente de vacinas contra a doença, pesquisadores da Universidade de São Paulo (USP) identificaram marcadores moleculares que podem servir, no futuro, para o desenvolvimento de novas vacinas e terapias contra esse vírus. O trabalho também reiterou a eficácia da resposta imune induzida por dois [...]
