The flu vaccine is only for prevention but it does not mean there is 100% protection. If flu strikes, the effect will not be very debilitating on body.
Those who are immunity compromised, that is they have uncontrolled diabetes, are advised to take the vaccine.
Vaccine must be taken before the winter season begins as it takes three weeks for the immunity to build.
Avoid crowded places and ensure hand hygiene. In case of fevers, opt for self-isolation as it will protect near and dear ones. Take rest, drink sufficient water and eat a balanced diet.
