One of the flu vaccines approved for US use by the Federal Drug Administration (FDA) may have minuscule traces of formaldehyde that is used in the creation of the vaccine to inactivate ("kill") the virus. The vaccines approved for injection as flu shots in the US all use inactivated viruses in the vaccine. All three FDA approved A-H1N1/09 Pandemic flu vaccines use different chemicals in making the virus inactive. One uses formaldehyde for this part of the manufacturing process. After this use of the formaldehyde, the solution is further purified and most, if not all, of the formaldehyde is removed in that process. The ingredients list must include ANY traces of residual chemicals from manufacturing, no matter how insignificant. The final vaccine from one manufacturer may contain, in each 0.5 mL dose, residual amounts of formaldehyde, but not more than 100 mcg. (which has been proven safe by the recent human trials and approved by the FDA as negligible amounts). The use of this processing technique has been in place for years in the manufacturing process of some of the regular seasonal flu shots, and the incidence of any problems with those vaccines is extremely low and likely unrelated to the formaldehyde residual traces.

Everyone is encouraged to take the H1N1 immunization when it is made available to them. Like you can see when reading the label on other medicines, or even on a package of cookies at the grocery store, preservatives and other chemicals are a part of the manufacturing of items in everyday life, and when proven safe over time, there is no reason to be overly concerned or take the higher risk of catching the serious disease by refusing the immunization.

No. Of course it is. Watch out for the soft kill vaccine on the back of it. Bound to contain the carcinogen formaldehyde, like the Pandemrix Swine Flu hoax non-vaccine, which was withdrawn due to multiple cases of narcolepsy.

Do flu shots have formaldehyde in them?

Some of the brands of flu vaccines have traces of formaldehyde left after it was used to weaken or "kill" the virus used to create the vaccine. It is an insignificant amount. However, some brands of the vaccines do not have formaldehyde since they use other chemicals to weaken the virus. See the related question in the related questions section below for a full list of the ingredients used to make a flu vaccine brand by brand.

Can you get the flu from the vacine?

No, you cannot get the flu from the swine flu vaccine. What the H1N1 vaccine does is inject dead or weakened flu germs. That way if you do get the flu, your body will know what to do. But you can't get the flu from the vaccine.

Once you get a flu vaccine do you always have to get it?

The outer coating of the flu virus continually changes its shape. The flu vaccine uses a weak form of the virus with a similar shape to the most common types of flu. By the next year, a new type of flu is circulating. If you get a vaccine, it will be for a virus with a different shape. You will have the option of getting a vaccine for the new type of flu.

What is all in one flu vaccine?

Some flu vaccines are for a single type of flu virus, like the H1N1/09 vaccine in 2009. Others, like the seasonal flu shots we take each fall in flu season in the US, contain the ingredients for making you immune to three different flu viruses. Calling it an "All in One" flu shot is likely referring to the vaccines for multiple types of flu all in one shot.

Is the Swine Flu vaccine effective against the regular flu?

Each flu vaccine is targeted to specific varieties of the flu virus. Unless another type of flu is very similar to the targeted virus, it will not be prevented with that vaccine. Having said that, since the 2010-2011 flu season through to the current 2011-2012 season, the "regular" seasonal flu vaccine, which always contains three types of flu vaccine (trivalent), has included the swine flu along with the other two varieties to which the vaccine was targeted. So in that sense, at least currently, the swine flu vaccination is effective against the regular flu since vaccines for each type are put together in one vaccination.

Was the flu shot for 2010-2011 flu season also for the H1N1 virus?

Yes, it did also protect against the pandemic swine flu H1N1/09. So does the 2011-2012 vaccine. In the US, the first pandemic swine flu vaccine was available for the 2009-2010 flu season and was given in a separate vaccination than the "regular" flu vaccine for the seasonal flu. Then in 2010, the "regular" seasonal flu shot for the 2010-2011 flu season did contain vaccine for the H1N1/09 pandemic swine flu. The vaccination included that and two other virus vaccines. If you had a previous flu shot for swine flu, it won't hurt you to take a second dose this year and might help some people who may not have initially gotten a full immune response due to certain disorders.

Which has worst side effects the flu or the flu vaccine?

Does the US 2012-2013 flu vaccine contain swine flu vaccine?

This year's vaccine does contain Type A, H1N1/09 vaccine made from the specific type (i.e., mutation) of the H1N1/09 virus that is expected to circulate in the US in flu season this year. That specific strain is called: A/California/7/2009 (H1N1)pdm09-like virus The vaccines made from the other two selected influenza strains that are in the 2012-2013 flu vaccines in the US contain: A/Victoria/361/2011 (H3N2)-like virus B/Wisconsin/1/2010-like virus (from the B/Yamagata lineage of viruses)
