Are Redness And Swelling Normal Flu Shot Symptoms?

An annual flu shot is the best and most effective way to avoid an influenza infection, especially during the ongoing Covid-19 pandemic. Each year, the various forms of the virus cause thousands of deaths. Every year, a new vaccine is developed to combat the most recent influenza strain, and every year, many people notice redness and swelling after their flu shot – side effects which are perfectly normal and certainly not a cause for concern.

What other flu shot side effects are there?

There are some minor side effects associated with a flu vaccine, and all age demographics are susceptible to them, including seniors and children. As mentioned, side effects are generally limited to redness and swelling around the injection site and can be attributed to the injection itself.

Other side effects include:

  • Low grade fever
  • Body aches
  • Soreness
  • Nausea
  • Fatigue

These side effects are attributable to the body’s immune system and its reaction to the dead, inactive virus which makes up the vaccine. This is a standard response and is not indicative of flu infection or more serious side effects. The flu vaccine is unable to cause an infection of influenza.

Are there different side effects for different types of flu shots?

There are multiple different types of flu vaccines available, including egg-based, cell-based, and recombinant vaccines. They are distinguished according to how the virus— that which is responsible for the vaccine’s antibody production— is manufactured and treated before it is vaccine-ready. Furthermore, there are multiple different methods by which the vaccine is administered, via hypodermic needle, patch, or otherwise. The CDC does not have a preference among licensed vaccines. The flu vaccine for the 2021 – 2022 season protects against four types of influenza virus.

Regardless of which type of vaccine you get, all can potentially cause the side effects listed above. Any effects you may experience will typically go away within several days, after which you will be inoculated against the current season’s influenza strain for 4 – 6 months.
