News outlets are reporting this morning that the pharmaceutical giant GlaxoSmithKline is advising medical personnel in Canada that one of its batches of H1N1 flu vaccine may trigger a life-threatening allergy.
A GlaxoSmithKline spokesperson, Gwenan White, is quoted as saying the recall was issued after determining that one batch of H1N1 vaccine may be responsible for more allergic reactions than what is being seen with other batches.
The identified batch consists of 172,000 doses of the H1N1 vaccine. The spokesperson declined to divulge how many doses had already been administered before the recall was issued.
If you search the internet for “H1N1 vaccine” you are likely to find myths and misinformation mixed with the truth about the vaccine. Many public health officials are concerned that people are being frightened away from getting the H1N1 vaccine based on this campaign of misinformation and fear. Not only are health officials battling a quickly spreading and potentially deadly influenza virus, they’re also battling the arena of public misinformation about the vaccine that can prevent the illness.
Since the onset of H1N1 in April 2009 nearly 3,900 people, including about 540 children, are believed to have died from the H1N1 flu, the Centers for Disease Control and Prevention said Thursday. For the first time in over 50 years there is a vaccine against a pandemic strain of influenza before the beginning of winter, when low temperatures and humidity permit the H1N1 virus to spread more readily. Before you believe what you read on the internet, including the information on this web site, you should speak with a qualified health care professional to understand the truths, myths and risks involved with taking the H1N1 vaccine.
Here are some facts about the vaccine that should help you decide if the vaccine is the correct answer for you and your loved ones:
- The seasonal flu vaccine will not protect you against 2009 H1N1 flu.
- This vaccine is produced using the same processes and facilities that are used to make the currently licensed seasonal influenza vaccines.
- Inactivated 2009 H1N1 vaccine can be administered at the same visit as any other vaccine, including pneumococcal polysaccharide vaccine. Live 2009 H1N1 vaccine can be administered at the same visit as any other live or inactivated vaccine EXCEPT seasonal live attenuated influenza vaccine.
- Children through 9 years of age should get two doses of vaccine, about a month apart. Older children and adults need only one dose.
- CDC’s Advisory Committee on Immunization Practices (ACIP) recommends that certain groups of the population receive the 2009 H1N1 vaccine first. These target groups include pregnant women, people who live with or care for children younger than 6 months of age, healthcare and emergency medical services personnel, persons between the ages of 6 months and 24 years old, and people ages of 25 through 64 years of age who are at higher risk for 2009 H1N1 because of chronic health disorders or compromised immune systems.
- The U.S. Food and Drug Administration (FDA) has approved the use of one dose of 2009 H1N1 flu vaccine for persons 10 years of age and older. This is slightly different from CDC’s recommendations for seasonal influenza vaccination which states that children younger than 9 who are being vaccinated against influenza for the first time need to receive two doses. Infants younger than 6 months of age are too young to get the 2009 H1N1 and seasonal flu vaccines.
- The 1976 swine flu virus and the 2009 H1N1 virus are different enough that it’s unlikely a person vaccinated in 1976 will have full protection from the 2009 H1N1. People vaccinated in 1976 should still be given the 2009 H1N1 vaccine.
- People who are allergic to eggs might be at risk for allergic reactions from receiving influenza vaccines, including the 2009 H1N1 vaccine.
- The H1N1 flu vaccine will not prevent “influenza-like” illnesses caused by other viruses.
- In 1976, an earlier type of swine flu vaccine was associated with cases of Guillain-Barré Syndrome (GBS). Since then, flu vaccines have not been clearly linked to GBS.
If you experience a severe reaction to the vaccine such as a high fever, behavioral changes, difficulty breathing, hives, paleness, dizziness or a fast heartbeat you should go to health care facility immediately. Be sure inform the doctor of what happened, when it happened and when the vaccine was administered. Ask your health care provider to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS).
In summary, educate yourself on the pros and cons of receiving the H1N1 vaccine and make an educated determination only after discussing with your health care provider. Be Healthy!
