The flu vaccine cannot give you allergies to something. As someone that has done experiments with vaccines, this post is absolutely incorrect. The flu vaccine is an attenuated (weakened) version of whichever influenza strain is most prominent that year and thus does nothing to you that getting sick with influenza wouldn't do on its own except because it is weakened it does not negatively impact your health by making you sick. They weaken the virus by putting it in chicken eggs and letting it reproduce until live viral count is low but viral capsules are numerous (the shell of the virus) and then they put the solution in glycerin (absolutely harmless) and freeze dry it. After that it is shipped to the country of use, water is added, and then they inject it into your arm. The immune system finds the antigens and makes antibodies, and after the production of antibodies has been made,  your B-cells memorize the antigens on those viral capsules and if they ever encounter those antigens they produce the antibodies for them making your immune response much much faster (between 10 and 100 times) which also prevents you from being able to spread the virus yourself. You are sharing blatant lies and are putting people at risk by doing so.
