A)"A type of paralysis that affects movement on both sides of the body that mayeven involve the respiratory muscles"
B)"Swelling of your arm where you got your flu shot, and maybe your eyes and lips had some swelling as well"
C)"A degenerative disease where you have trouble walking without the help of a cane or walker"
D)"Influenza-like illness where you had fever and chills for 2 to 3 days after your last flu shot"

Question 11
