Yes, they can, depending on the virus you have. Immunocompromised people with the HIV/AIDS virus may not get full immunization from a vaccine since their body doesn't respond to infections like other people's bodies. If it is a flu virus, there is no problem getting a vaccination unless you have a high fever from the virus. They will ask you about any recent fevers when you go to get the vaccination. The problem if you are sick with a virus is that your body's immune system is working very hard to get rid of the virus you have, if you add the vaccine for a different virus to your body, it has to work twice as hard to deal with both at the same time, and you may not get a good response to the vaccine.
They do work for the particular strain of the virus. The reason it doesn't stop everything is because the virus will mutate making a whole new strain and also making it impossible to have vaccines for every kind of flu out there.
Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.
Vaccines are made using the disease-causing virus or bacteria.
A target Virus is a virus that is a Bio-safety level 4 virus. It is the target of vaccines.
To put it simple, your body is injected with either the weak or already dead virus that you want to be immune to. Because the virus is not strong, your immune system can fight it easier but still gain the immunity during the process to avoid being sick, or at least not as bad as you normally would, if you ever catch the real virus in the future.
vaccines.
An antiviral acts to kill a virus already present in the body. A vaccine helps your body fight off the virus so it never gets into your body in the first place.
No. This is a problem with an inability to taste. It is not caused by a virus or bacteria. Vaccines are not medicines for this kind of disorder.
nothing. vaccines insert a dead or weakened form of the virus or bacteria into your bloostream.
No, they are made from the virus
virus - antivirals, or let the immune system handle itbacteria - antibioticsin both cases vaccines can be used as a preventative. but once infected most vaccines can do little.
No, the vaccines are purified and treated to remove any such contaminants. Any bacteria mixed in with the virus and vaccine medium would not be helpful, the multi-use vials of vaccines contain preservatives to prevent bacterial growth.The H1N1/09 influenza is caused by a virus. Some particles of "dead" H1N1/09 virus (or in some types of the vaccines-weakened live virus), are the active ingredient in the vaccines that make our bodies become immune to that specific virus. Bacteria play no role in this process.
