(Question) Inquiry about flu vaccination for seniors (concerns after receiving COVID-19 vaccine)

Hello. I'd like to inquire about flu vaccinations for my parents (aged 65 or older).

Although we frequently receive text messages from the district office informing us about flu shots,

Parents are hesitant to get a flu shot because of negative experiences and anxiety about the discomfort and side effects they experienced after receiving the COVID-19 vaccine in the past.

In this situation, I would like to ask for your expert opinion on the necessity and safety of flu vaccination.

Differences between the flu vaccine and the COVID-19 vaccine: Are there any differences in the incidence of side effects or the presentation of symptoms between the flu vaccine and the COVID-19 vaccine? Beyond the mild side effects (e.g., injection site pain, low-grade fever) that are common in the elderly, I'm curious if the risk of serious systemic reactions, which my parents are concerned about, is low.

The Importance of Vaccination: It would be helpful to convince your parents that the flu can lead to complications beyond just a cold, and that vaccination can help prevent these risks.

Optimal Vaccination Timing and Precautions: If you decide to vaccinate, please advise whether it is appropriate to vaccinate now and whether there are any health conditions or lifestyle habits that parents should be particularly aware of before and after vaccination.

I will wait for an explanation, with your parents' health and safety as my top priority. Thank you.
