Yes, there are two main types of influenza vaccines licensed in the U.S.: inactivated influenza vaccines (IIVs), which are made from killed virus, and live attenuated influenza vaccines (LAIVs), which contain weakened virus. IIVs are typically given as an injection, while LAIVs are administered as a nasal spray. Both types aim to provide immunity against the most common strains of the influenza virus. Additionally, there are variations within these categories, including high-dose and recombinant options.

Name two common vaccines?
Two common vaccines are the influenza vaccine, which helps protect against seasonal flu viruses, and the measles, mumps, and rubella (MMR) vaccine, which provides immunity against these three contagious diseases. Both vaccines are essential for public health and play a significant role in preventing outbreaks and protecting vulnerable populations.
What is the difference between Influenza A and Influenza B?
Influenza A and Influenza B are two different types of flu viruses. Influenza A is more common and can infect both humans and animals, while Influenza B mainly affects humans. Influenza A has more subtypes and can cause more severe outbreaks, while Influenza B typically causes milder illness.
What is the difference between flu A and flu B?
Influenza A and influenza B are two different types of the flu virus. Influenza A is more common and can infect both humans and animals, while influenza B mainly affects humans. Influenza A has more subtypes and can cause more severe outbreaks, while influenza B typically causes milder symptoms.
Does the influenza virus readily change the expressions of its genetic material?
RNA genome of influenza virus is segmented in to 7 pieces. It has the unique property of undergoing two types of genetic variation ie antigenic drift and antigenic shift. In antigenic drift the antigenic variations are minor where genetic recombination take place between strains of two similar species whereas in antigenic shift the recombination take place between strains of dissimilar species leading to major antigenic variations and hence seasonal epidemics.
Is type A Influenza the same as H1N1 Swine Flu?
Swine Flu (and other H1N1 flu viruses) is a Type A influenza, but all Type A influenza viruses are not swine flu, or other H1N1 viruses. Swine flu is just one of many subtypes of Type A influenza. Swine Flu is caused by the Type A H1N1/09 Virus.
Are the two Australian vaccines for rabies interchangable?
Modern vaccines are interchangeable. But this should not be done normally.
What is a vaccine that contains live weakened pathogens?
They are called live attenuated vaccines. Attenuated means weakened. The nasal mist flu vaccine is an example of a live attenuated vaccine. The vaccines for flu that are injected are made from pieces of viruses or "dead" viruses. See the related question below for more information on these two types of vaccines.
What are Two groups of microbes?
vaccines and antibiotics
Why isn't Baxter Swine Flu on the news?
Baxter was contracted to work on the manufacture of a pandemic swine flu vaccine for Europe, but at the time that two vaccines were approved, the third one made by Baxter did not yet pass the committee's approval process. It is still being considered, however.The European Medicines Agency (EMEA) has so far approved two vaccines for the A-H1N1/09 influenza that are manufactured by GlaxoSmithKline and Novartis. The brand names are Pandermix and Focetria.
How many vaccines are there?
Two: The nasal inhalant, and the injection.
Do all flu viruses have H N?
All Type A influenza viruses have H and N (these are two proteins that are on the outer shell of the virus particle--Hemagglutinin and Neuraminidase). The other influenza virus types B and C each only have one serotype and they do not include the H and N.
How many vaccines are there for the Swine Flu?
Two. In the 2010-2011 flu season in the Northern Hemisphere, the vaccine for the H1N1/09 virus is available included in the regular seasonal flu vaccination. There are two types of these vaccines, one for injection and one for nasal spray administration. There is no need for a separate swine flu shot this year like in the pandemic of 2009.
