Why might it be more difficult to prepare a vaccine against noroviruses than against rotaviruses?

Biology
1 answer:
White raven [17]3 years ago
7 0

Designing efficacious norovirus vaccines remains a major challenge due to several factors:

(1) the extreme genetic variability within the norovirus family and within genogroups

(2) the rapid evolution of antigenically dissimilar pandemic GII.4 norovirus strains

(3) the lack of lasting immunity upon natural exposure to noroviruses in at least a proportion of the population.

What would be the result if you had a hypotonic solution with a cell in it?
nadya68 [22]

I wanted to be with you alone

And talk about the weather

But traditions I can trace against the child in your face

Won't escape my attention

You keep your distance via the system of touch

And gentle persuasion

I'm lost in admiration, could I need you this much?

Oh, you're wasting my time

You're just, just, just wasting time

Something happens and I'm head over heels

I never find out until I'm head over heels

Something happens and I'm head over heels

Ah, don't take my heart, don't break my heart

Don't, don't, don't throw it away
