If the influenza vaccine is to be made from a live virus, then the strain is selected, grown, and then weakened (usually chemically) to be able to trigger an immune response but not be strong enough to cause the infection. If it is to be made using a "dead" or inert virus that also does the same to trigger immune response and antibody production without causing infection, then the virus is grown and then made inactive before being used in the vaccine.
Once the virus particles needed are produced one of the two ways above, they are purified, isolated and combined with administration medium that is either for injection or for use with a mist/inhalation administration medium.
There are sometimes adjuvants added that will make a little go a long way (these are not used in the US flu vaccines). This way smaller doses are needed and so more vaccine can be distributed to more people in shorter times. This is helpful if the strain is not easily or quickly grown and vaccine is needed quickly.
There are also preservatives added to maintain the purity of the vaccine. This is needed especially in multi-dose vials that are not used entirely upon opening of the sterile vials. Single dose vials and syringes are usually available without the addition of these preservatives for people with special needs or Allergies to the preservatives.

What agency has prepared for future pandemics by creating a global action plan for the influenza outbreak?
The World Health Organization (WHO) has prepared for future pandemics by creating a global action plan to address influenza outbreaks. This plan emphasizes enhancing surveillance, strengthening health systems, and promoting research and development of vaccines and antiviral treatments. The goal is to improve preparedness and response strategies for potential influenza pandemics on a global scale.
How many chromosomes does influenza?

Is influenza caused by bacteria?
No, influenza is caused by viruses, specifically the influenza virus. Influenza viruses can infect the respiratory tract and lead to symptoms such as fever, cough, and body aches. Antibiotics, which are used to treat bacterial infections, are not effective against the influenza virus.
Why does influenza have RNA?
Influenza is an RNA virus because its genetic material is made up of RNA. RNA viruses like influenza are able to mutate more rapidly than DNA viruses, which contributes to the virus's ability to evolve quickly and evade host immunity.
Are Influenza vaccines prepared from blood products?

What is a killed virus vaccines?
Cholera Vaccine. Flu vaccines formulated for injection use inert/inactive virus particles ("dead"), while flu vaccines for nasal mist are made as a LAIV (live attenuated influenza vaccine), which means they are "alive" but weakened chemically to prevent them from being able to cause illness.
What are the different types of Influenza?
According to the United States Department of Health and Human Services, there are 2 types of influenza vaccines - trivalent and quadrivalent.

What is la iv vaccines?
Live attenuated influenza vaccine (LAIV) is a type of influenza vaccine in the form of a nasal spray that used to be recommended to prevent influenza.
What type of vaccine falls into the innate immunity?
Most live attenuated vaccines (influenza vaccines in humans, infectious bronchitis and Newcastle disease vaccines in chickens are types that activate innate immunity responses.
What type of influenza vaccine should a pregnant woman receive?
Only those that are made from inactive "dead" virus particles and not the LAIV Live Attenuated Influenza Vaccines. That means that you should get injected vaccines for the flu instead of the nasal mists that contain "live" but weakened viruses. See the related question below for the recommendations from gynecologists and obstetricians for flu vaccinations in pregnancy.
As of 2007 is thimerosal in any vaccines in the US?
