( ed with other chemicals into the blood...)Engineer ramps up protein production, develops versatile viral spheres

ed with other chemicals, into the bloodstream with the hope that they will provoke a strong, albeit general, response by the immune system. The process is akin to advertising a product to a random audience and hoping some consumers become interested.

With an engineered capsid, in contrast, a vaccine maker could attach a very specific protein designed to stimulate only the appropriate immune-system cells. A vaccine with these well-targeted capsids would be more likely than a traditional vaccine to elicit a strong and specific response. The capsid method is akin to advertising a product directly to the people who are most likely to want it.
