Todos estamos a la espera de una vacuna contra #COVIDー19

Pero te has preguntado ¿cómo funciona el sistema inmune y las vacunas?

¡Aquí una breve explicación! 🧵
El sistema inmune protege al huésped de los patógenos invasores de 2 formas: 1) La inmunidad innata actúa en minutos para eliminar el patógeno. 2) La inmunidad adaptativa lleva días-semanas, pero es específica y de larga duración, y es la base de las #vacunas (2)
La inmunidad innata activa sensores que detectan moléculas, conocidas como reconocimiento de patrones. Una vez que estos sensores detectan patrones microbianos (#PRR), activan una alarma inmediata a través de la secreción de #citoquinas e #interferones (3)

How does the immune system work? Will there be #COVID19 vaccines? @BioRender & I put together ‘immunology 101 tweetorial for non-immunologists’. @jerryguartist, @shizaoki, @JungHeeSciViz also made this accompanying video. Please share widely! (1/n)

The immune system protects the host from invading pathogens through 2 layers: the innate and adaptive immunity. Innate immunity acts within minutes to remove the pathogen. Adaptive immunity takes days/wks but is specific & long lived, and is the basis for #vaccines. (2/n)
Innate immunity starts by triggering sensors that detect unusual molecules or activities, known as pattern recognition. Once microbial patterns are detected by these sensors (#PRR), they trigger immediate alarm through secretion of #cytokines and #interferons. (3/n)
