Barbara, you bring up an important topic and that is the flu shot. Now is the time of year to think about getting your flu shot because flu season can begin as early as mid-October. It takes your body about two weeks to build up the antibodies to the flu so the vaccine will protect you. Inactivated vaccines use a killed virus to create the antibody response in your immune system.

There are three types of vaccines you can get this year:

  1. The regular flu shot. This type of vaccination is good for anyone over the age of six months.
  2. The high-dose shot. This is best for people 65 years old and older.
  3. The intradermal flu shot. This type of vaccine is new this year and is given under the skin. This is only for people who are 18 to 64 years old.

When you get the flu shot, you may experience some soreness, redness or swelling at the injection site. For the intradermal version of the vaccine, you might experience some itching. With all of these variations, you may also get a slight fever for one to two days. These symptoms all generally go away after one or two days.

If you prefer not to get a shot at all, there is the nasal spray vaccine. It is made from a weakened virus, but like the flu shot, it will not give you the flu.

Generally, you cannot get dizzy after the flu shot after six days. It’s important that everyone think about getting their vaccine because while the side effects from the vaccine are very mild, getting the flu and its side effects can be very serious.
