One of my friends has allergic rhinitis and has been prescribed an oral vaccine. He is allergic to 3 different classes of substances and so, has been given 3 different types of vaccines. He has to place them below his tongue.
I am curious about some of the procedures he has to follow.
1.How does a vaccine of this type work ?
2 He has been given 2 vials for each type of vaccine. First one is labeled SRS and other one as I understand is - it's allergen. So, What is SRS ? What's the requirement of it ?
3 It is written in the instructions that he should not eat anything one hour before and one hour after taking the vaccine. Why ?
