Adults 65 years and older; Children younger than 2 years old. People with Asthma;
Chronic lung disease (such as chronic obstructive pulmonary disease and cystic fibrosis);
Endocrine disorders (such as diabetes mellitus);
People who are obese with a body mass index of 40 or higher;
People with a weakened immune system.
Flu vaccination during pregnancy helps protect pregnant people from flu during and after pregnancy and helps protect their infants from flu in their first few months of life.
The vaccine comes in inactive and weakened viral forms. The live, weakened vaccine is generally not recommended in pregnant women, children less than two years old, adults older than 50, or people with a weakened immune system.

Flu vaccine only protect against flu its complications, not other illnesses.
For example: someone can get sick with another respiratory virus besides flu. Such as Rhinoviruses, or Covid-19. Or other respiratory viruses can cause symptoms similar to flu.
After flu vaccination around 2 weeks are needed to develop immunity against influenza virus.
If person infected before vaccination, he or she can still get sick with flu, before vaccination takes effect.
