What are the negatives, if any, of getting the flu vaccine?

Hardly any: Flu vaccine is very safe. Vast majority of people will have nothing worse than a slightly sore upper arm. Even if you get the flu later in the season it's likely to be mild. It's recommended for nearly everyone.Pregnant women are strongly encouraged to get the flu shot because they are more susceptible to complications including death. People who have chronic conditions should get it too.

Negatives flu Vaccin: Side effects which are mostly minor like local swelling and soreness and redness, low grade fever, and not feeling good in few people for 48 to 72 hours, and very rarely reported guellen barre syndrome, and severe allergic reaction.

Reactions: While it is considered "generally safe", many people do have some adverse reactions to the vaccine. Some people get sick afterwards (probably an autoimmune reaction); I have seen anaphylaxis after the flu vaccine and have seen other patients complain of a metal taste in their mouth. For some it is great and they never miss a flu vaccine and for others it causes problems.

Flu shots are GOOD.: Flu shot side effects may include: slight swelling, redness or pain at vaccination site. If headache, nausea, fever or muscular pain occur they usually resolve within one to two days. You won't get the flu from a flu shot because the virus either contains inactivated virus or doesn't have virus particles in it. Severe side effects are rare.
