No it changes that's why you need a new flu shot every year. Otherwise we would only need one and it would be done.
No, if you have it you will be immune to it after that. However, viruses are able to mutate to slightly different strains rapidly. If that happens and you are exposed, you may still have some immunity, but you may not, in which case you could get the flu from a similar but different form of the virus.
Because there are many strains of flu virus, so unless you have immunity to them all you will catch flu again.
Yes. Once you have caught swine flu you cannot catch it again.
yes and no because if you had the swine flu once and you get vaccinated you propelywont get it again.
Being around other people who have the flu will only make you immune if you come down with the flu yourself. There are no etherial substances (none discovered as yet, at any rate) that pass through the air to healthy people, thus immunizing them. To the contrary, influenza virus particles easily waft through the air, and, depending on the flu variant, arrive at their destination (your throat perhaps?) ready to infect someone else.If you're interested in becoming immune to a given flu, we recommend getting immunized with a vaccine approved by your government. For most people, that's far, far better than actually becoming infected.
no usually once you pass the flu to one member in the family it does not keep going around. if you get it again which may not happen once you have had it it will most likely be from a stranger or someone not in your close family
Because you have been near someone with it and you are not immune to it. After you have it you should be immune to it though.
No, you are not immune to swine flu. Swine flu is transmitted in the same way as regular flu - coughing, sneezing, touching, etc., not through eating pork.
Getting the flu shot is crucial for individuals without a spleen because they are at a higher risk of infection due to a weakened immune system. The flu shot can help reduce the risk of serious flu-related complications and hospitalizations in this population. It is recommended to consult with a healthcare provider to determine the most appropriate vaccination schedule.
No!
Well... Nothing has proved anything like it so i sould guess,but it could affect your immune system in a bad way if it was far ago because it wasnt prepared so it would be the same.
Your immune system is the only thing that can get rid of it. If you do get a flu, just keep warm and drink things that contains Vitamin C to boost your immune system.
