If I was to be to be stung be a bee/wasp for the first time could I have a severe allergy reaction?

It's possible. It's possible to have a severe allergic reaction to a bee/wasp sting. Approximately 2 million Americans are allergic to the venom of stinging insects. Many of these people are at risk for life-threatening allergic reactions. About 50 deaths each year in the U.S. are due to allergic reactions to insect stings. So please be careful and try to avoid being stung. Have a nice day!
