What happens if a horse doesn't get a flu vaccine?

For the 3-6 months that the vaccine would have provided an improved immunity against influenza, the unvaccinated horse will be more susceptible to contracting influenza than a vaccinated horse.


Why is it impractical to include influenza vaccinations in the required childhood vaccinations?

There are many different strains of influenza. This is why you get a flu shot (or could) every year. So making a required vaccine would only protect the child for that one year.


What side effect does the H1N1 vaccine have on an unborn child?

The Food and Drug Administration (FDA) approved the inactivated ("dead") virus vaccines for pregnant women. The nasal mists containing live weakened virus is not approved for pregnant women. The risk to the unborn fetus was considered in the trials and approval process. The guidance from the CDC is very clear that the risk of not getting vaccinated against A-H1N1/09 to pregnant women and their unborn fetus is much greater than the risk of using the vaccines. Obstetricians are recommending H1N1/09 vaccinations to their patients. The vaccine is made exactly like the seasonal flu shots have been made for decades with a proven safety record, so there is no reason to think the same vaccine made with inert particles from a different virus strain would prove any less safe.The following are excerpts from a September 3, 2009guidance document from the US Centers for Disease Control and Prevention (CDC), 2009 H1N1 Influenza Vaccine and Pregnant Women:Influenza vaccines have not been shown to cause harm to a pregnant woman or her baby. The seasonal flu shot (injection) is proven as safe and already recommended for pregnant women. The 2009 H1N1 influenza vaccine will be made using the same processes and facilities that are used to make seasonal influenza vaccines.It is important for a pregnant woman to receive the 2009 H1N1 influenza vaccine as well as a seasonal influenza vaccine. A pregnant woman who gets any type of flu is at risk for serious complications and hospitalization. Pregnant women who are otherwise healthy have been severely impacted by the 2009 H1N1 influenza virus (formerly called "novel H1N1 flu" or "swine flu"). In comparison to the general population, a greater proportion of pregnant women infected with the 2009 H1N1 influenza virus have been hospitalized. In addition, severe illness and death has occurred in pregnant women. Six percent of confirmed fatal 2009 H1N1 flu cases thus far have been in pregnant women while only about 1% of the general population is pregnant. While hand washing, staying away from ill people, and other steps can help to protect pregnant women from influenza, vaccination is the single best way to protect against the flu.There are two types of flu vaccine. Pregnant women should get the "flu shot"- an inactivated vaccine (containing fragments of killed influenza virus) that is given with a needle, usually in the arm. The flu shot is approved for use in pregnant women. The other type of flu vaccine - nasal-spray flu vaccine (sometimes called LAIV for "live attenuated influenza vaccine)-is not currently approved for use in pregnant women. This vaccine is made with live, weakened flu viruses that do not cause the flu). LAIV (FluMist®) is approved for use in healthy* people 2-49 years of age who are not pregnant. In addition to protecting her from infection, infants less than 6 months old will not be able to be vaccinated so it is recommended that everyone who lives with or provides care for infants less than 6 months of age receive both the seasonal influenza vaccine and 2009 H1N1 influenza monovalent vaccine to provide protection for the infant.One recent study conducted in Bangladesh, assessed the effectiveness of influenza immunization for mothers and their young infants. Inactivated influenza vaccine reduced proven influenza illness by 63% in infants up to 6 months of age. This study confirmed that maternal influenza immunization is a strategy with substantial benefits for both mothers and infants. There is no evidence that thimerosal (used as a preservative in vaccine packaged in multi-dose vials) is harmful to a pregnant woman or a fetus. However, because some women are concerned about exposure to preservatives during pregnancy, manufacturers will produce preservative-free seasonal and 2009 H1N1 influenza vaccines in single dose syringes for pregnant women and small children. CDC recommends that pregnant women may receive influenza vaccine with or without thimerosal. People for whom the 2009 H1N1 influenza vaccine is recommended should receive it, even if they have had an influenza-like illness previously, unless they can be certain they had 2009 H1N1 influenza based on a laboratory test that can specifically detect 2009 H1N1 viruses. CDC recommends that persons who were tested for 2009 H1N1 influenza discuss this issue with a healthcare provider to see if the test they had was either an RT-PCR or a viral culture that showed 2009 H1N1 influenza. There is no harm in being vaccinated if you had 2009 H1N1 influenza in the past.Pregnant women are encouraged to get vaccinated against the flu. As always, when pregnant, check with your obstetrician before taking any medication.You should not get the vaccine if you are allergic to eggs** or sulfa drugs. Inform your health care professional if you have ever had a severe (life-threatening) allergy to eggs or to any other substance in a vaccine (some vaccines contain traces of neoporin, gentamicin and polymixin).**New studies show that an allergy to eggs, or other chicken proteins, may not prohibit some people from getting a flu vaccination.

Are flu pills bad when your pregnant?

See also the related question below for the current recommendations fromthe American Congress of Obstetricians and Gynecologists.My doctor actually recommended I get the flu shot while I was pregnant. I did and everything is still going fine.Here in UK pregnant women are not on the list of people who should receive flu shots, but I was asked this question (I am a midwife) and did some research and in US pregnant women are up there with the elderly, people with heart/lung disease and diabetics as people who should have flu shots.I have copied this over from the CDC website:"Is it safe for pregnant women to receive an influenza vaccine that contains thimerosal? Yes. A study of influenza vaccination examining over 2,000 pregnant women demonstrated no adverse fetal effects associated with influenza vaccine. Case reports and limited studies indicate that pregnancy can increase the risk for serious medical complications of influenza. One study found that out of every 10,000 women in their third trimester of pregnancy during an average flu season, 25 will be hospitalized for flu related complications.The trace amounts of mercury from the thimerosal in vaccinations (a preservative) are about the same amount as you would get from a single meal of fish.The following excerpts from a September 3, 2009 guidance document from the US Centers for Disease Control and Prevention (CDC) are about the H1N1/09 Influenza Vaccine and Pregnant Women:Influenza vaccines have not been shown to cause harm to a pregnant woman or her baby.

That vaccine for seasonal flu is already distributed and available for use. The two kinds of vaccine (seasonal flu and "Swine Flu") must both be taken for complete protection from both kinds of flu in the upcoming flu season.Always check with your obstetrician before taking any medications in pregnancy. Your doctor may also be planning on administering the vaccines to patients.Note about H1N1 vaccines approved for use in the UK:These vaccines are slightly different from the vaccines approved for use in the US for A-H1N1/09, but are still recommended by the NHS for pregnant women. The difference is mostly that they contain adjuvants in the UK. See the related question below about swine flu shot ingredients.

Why should people with heart and lung disease get the influenza vaccine?

Because they are at higher risk of complications and even death from the flu than those without underlying diseases or disorders. See the related question below for a list of the high risk population in swine flu, which would be very similar, if not the same, for any type of influenza.


Do small animal vets give the animals flea baths?

There is not currently a widely-used influenza vaccine for animals, but a veterinarian would be the one to give it to your pet if there was one.


Are there helpful bacteria in the H1N1 09 vaccine?

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.


Would you use tetracycline to treat flu?

No, the flu, if you mean it as influenza and not just another name for a common cold, is a virus. Tetracycline is used for bacterial infections. It would not have an effect on influenza. The best treatment for the flu is to prevent it with a vaccine, but there are also drugs out there that have been proven somewhat beneficial for the treatment of flu. This would be a drug like oseltamivir (tamiflu). An important distinction here is that many people get sick and just say they have the flu, when in reality they just have some random viral or bacterial upper respiratory infection. To be certain one has the flu, he/she would need to be tested specifically for a strain of the influenza virus.


Who is the H1N1 shot vaccine best for?

It is best for everyone who can to get vaccinated whether they get the shot or the nasal mist. There are specific indications for who can not take the nasal mist attenuated live vaccine. Those most at risk for complications or death from the influenza virus should also be vaccinated if they are not among those who should not use a vaccine. If everyone could get the vaccination, we would all be better protected. See the related questions below for who should not get this vaccine and who is at highest risk for the H1N1/09 flu and for information on whether a mist or a shot is better.


Is there mercury in a flu shot?

Yes, but only tiny traces. The 2011-2012 flu season vaccine is made exactly like flu vaccines have been made for decades (including thimerosal) with an extremely high safety record even compared to other vaccines. The minuscule amount of mercury from the thimerosal preservative used in some doses of influenza vaccine may leave traces present in your body for a very short time. Single dose vials of the flu vaccines have no thimerosal in them, therefore no mercury, but may need to be special ordered in advance by your pharmacy or doctor, which may in turn raise the cost.However, to put this in perspective, the amount of mercury from that compound in the flu vaccine when used, is approximately 24.5 mcg of mercury per dose of vaccine. This is well below the amount of mercury that a single serving of fish in your diet might contain.Fish that are known to contain low amounts of mercury include catfish. It has been determined that for the amount of mercury in catfish to pose any potential danger, these hypothetical health risks from the mercury in catfish would only begin at a weekly intake of 342.8 ounces (21.4 pounds) of the fish. This should put into perspective the insignificance of the mercury from a flu shot. Scientific studies have proven no connection between thimerosal and untoward health consequences from vaccine use.The following is quoted from the Centers for Disease Control and Prevention (CDC) website:What is thimerosal?Thimerosal is a very effective preservative that has been used since the 1930s to prevent contamination in some multi-dose vials of vaccines (preservatives are not required for vaccines in single dose vials). Thimerosal contains approximately 49% ethylmercury. There is no convincing evidence of harm caused by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site. However, in July 1999 the Public Health Service (PHS) agencies, the American Academy of Pediatrics (AAP), and vaccine manufacturers agreed that thimerosal should be reduced or eliminated in vaccines as a precautionary measure.Today, all routinely recommended licensed pediatric vaccines that are currently being manufactured for the U.S. market, with the exception of influenza vaccine, contain no thimerosal or only trace amounts. Thimerosal preservative-free influenza vaccines are available, but in limited quantities. The total amount of inactivated influenza vaccine available without thimerosal as a preservative will continue to increase as manufacturing capabilities are expanded.Does the influenza vaccine contain thimerosal?Yes, the majority of influenza vaccines distributed in the United States currently contain thimerosal as a preservative. However, some contain only trace amounts of thimerosal and are considered by the Food and Drug Administration (FDA) to be preservative-free. Manufacturers of preservative-free flu vaccine use thimerosal early in the manufacturing process. The thimerosal gets diluted as the vaccine goes through the steps in processing. By the end of the manufacturing process there is not enough thimerosal left in the vaccine to act as a preservative and the vaccine is labeled "preservative-free".Is it safe for children to receive an influenza vaccine that contains thimerosal?Yes. There is no convincing evidence of harm caused by the small amount of thimerosal in vaccines, except for minor effects like swelling and redness at the injection site due to sensitivity to thimerosal. Most importantly, since 1999, newly formulated thimerosal preservative-free childhood vaccines (Hepatitis B, Hib, and DTaP) have been licensed. With the newly formulated childhood vaccines, the maximum total exposure during the first six months of life will now be less than three micrograms of mercury. Based on guidelines established by the FDA, the Environmental Protection Agency (EPA) and the Agency for Toxic Substances and Disease Registry (ATSDR), no child will receive excessive mercury from childhood vaccines regardless of whether or not their flu shot contains thimerosal as a preservative.Rsearch suggests that healthy children under the age of 2 are more likely than older children and as likely as people over the age of 65 to be hospitalized with flu complications. In addition, children between 24-59 months of age have higher rates of influenza-related doctor and Emergency Department visits than older children. Therefore, vaccination with either reduced or standard thimerosal-content flu vaccine is recommended for children between the ages of 6 and 59 months by CDC's Advisory Committee on Immunization Practices.Is it safe for pregnant women to receive an influenza vaccine that contains thimerosal?Yes. A study of influenza vaccination examining over 2,000 pregnant women demonstrated no adverse fetal effects associated with influenza vaccine. Case reports and limited studies indicate that pregnancy can increase the risk for serious medical complications of influenza. One study found that out of every 10,000 women in their third trimester of pregnancy during an average flu season, 25 will be hospitalized for flu related complications.Additionally, influenza-associated excess deaths among pregnant women have been documented during influenza pandemics. Because pregnant women are at increased risk for influenza-related complications and because a substantial safety margin has been incorporated into the health guidance values for organic mercury exposure, the benefits of influenza vaccine with reduced or standard thimerosal content outweighs the theoretical risk, if any, of thimerosal.Some types do, although it is a very scant amount. Multi-dose vials of vaccines for some types of flu must have preservatives added and usually the one used is thimerosal. Thimerosal contains trace amounts of mercury. However, to put it in perspective, it is no more than the amount of mercury you would get when eating a single meal of fish. It has been proven safe for use as the preservative over decades of use in flu shots. If you are concerned, you can ask for vaccination with a single dose vial or pre-filled single dose syringe which do not contain the preservatives, however, these are not always available and you would need to plan in advance to find single dose preparations.
