I am reading this paragraph about RS killed-vaccine in Encyclopedia of Virology, Third Edition (2008), vol. 3, pp. 70-77
What is this data called by which you can say that the frequencies of eosinophils and neutrophils increased within airways?
I think sample is first taken from throat and cultivated on some general culture (blood agar). Then, specimen is looked under microscope. Similarly done for the sample after vaccine. Then, visual comparison with identifying visually eosinophils and neutrophils.
Is the conclusion made based on culturing, microscopy and visual sampling by eye?
I am not sure anymore if this technique is useful at all. Mass spectrometry can give different intensities and masses. If so, the intensity of the corresponding peaks should be greater after the vaccine. Can this kind of conclusion be made based on mass spectrometry?
Interesting would be to know the exact spectrum of eosinophils and neutrophils after the vaccine. I think they do not increase proportionally. The one increases more than the other.
