chemistry1111 I think you might be referring to part D here
For part C though, you’d just have to say preventative measures to reduce transmission of a respiratory disc ease ex- wearing face masks, not sharing the food/drink which they did, or using handsanitiser to kill viral particles on their hands
For part D - you’d have to specific to Pat’s case - because she’s already received her vaccine - the humoral immune response would’ve kinda already occurred before she got infected at the movie theatres- so now its more like the response she’d have with a booster shot with the second exposure to the same pathogen
So you might modify your response like this
- The viral antigen would be recognised as “non self” by the T helper cells which would release cytokines
- Activating the B and T memory cells that were previously produced from the vaccine
- This may cause memory cells to rapidly differentiate into plasma cells
- That secrete large numbers of antibodies at a much faster rate than the first exposure to the flu virus
- Stimulating a stronger, faster greater immune response as the antibodies would quickly agglutinate the viral pathogens making it easier for phagocytes too detect, engulf and destroy them
- Preventing Pat from being infected and developing symptoms of the flu
Hope this helps and is concise enough 🙂😅
