Fear the Flu More than the Flu Vaccine

I have previously written on this site about the Influenza A(H1N1) virus and the possibility, however unlikely, of this virus becoming a catastrophic pandemic. In my first post, I was concerned that the general public was being driven toward unnecessary panic by a “media firestorm” of negative “swine flu” news coverage. Now, however, I have fears of the exact opposite. It seems that people may not be taking this virus seriously enough! As I said in my first article, we really do not know how deadly this virus will be, and the truth is that there is nothing about this virus, particularly its genome, that suggests it will be a catastrophic killer. However, influenza is always deadly and it needs to be taken seriously.

It seems that these days people are more terrified of vaccines than the diseases they are designed to prevent. This is, at least partially, due to a massive campaign to convince people that vaccines cause autism. However, there has been absolutely no scientific evidence of a vaccine-autism link. None. In relation to influenza vaccines, people are worried about a variety of issues, not the least of which is the speed at which the vaccine was produced and made available. An article in the NY Times last week by Paul Offit, a professor and expert on infectious diseases and vaccines at the University of Pennsylvania, addressed this and several other myths about the H1N1 vaccine.

…Here are some of those myths, and why they’re wrong:

SWINE FLU VACCINE IS UNSAFE The H1N1 virus revealed itself too late for it to be included in this year’s seasonal flu vaccine. But the H1N1-specific vaccine was manufactured in the same way as the regular vaccine: The shot form is made by growing the virus in hen’s eggs, purifying it and then treating it with a chemical that inactivates it. This technology has been used to make influenza vaccines for 60 years, and it has an excellent safety record. The nasal spray form is made by adapting the virus to temperatures below those typically found in the body. This allows it to reproduce in the relatively cool lining of the nose, but not in the lungs where it could cause harm. This technology has been used safely for more than 30 years. FluMist, a seasonal flu vaccine used since 2003, is made the same way.

THE VACCINE IS UNTESTED The H1N1 vaccine has already been given to thousands of volunteers to determine whether it could protect them from the virus and to make sure that it caused no adverse reactions. Only then did the Food and Drug Administration license it.

THE VACCINE CONTAINS A DANGEROUS ADJUVANT Some vaccines, like the hepatitis B and human papillomavirus vaccines, have substances called adjuvants, which are added to enhance the immune response, so that smaller quantities of vaccine can be given. Some people fear that the H1N1 vaccine contains, in particular, squalene, an adjuvant that, while included in other vaccines in Europe and Canada, has never been used in routine vaccines in the United States. But the H1N1 vaccine available in the United States has no adjuvant of any kind.

THE VACCINE HAS A DANGEROUS PRESERVATIVE Thimerosal, a preservative containing ethyl mercury that has been in vaccines since the 1930s, is used to prevent inadvertent bacterial and fungal contamination of multi-dose vials. H1N1 vaccine distributed in multi-dose vials will contain about 25 micrograms of ethyl mercury per dose. The issue of thimerosal received public attention in 1999 when the American Academy of Pediatrics and the United States Public Health Service took the precautionary step of asking that thimerosal be removed from single-dose vials of all vaccines. This was done in such a precipitous and frightening manner that it gave rise to the notion that thimerosal had led to autism or mercury poisoning. It hadn’t.

In fact, subsequent studies found that infants could safely receive eight times as much mercury as is contained in the H1N1 vaccine. But the public’s perception of thimerosal was damaged. This year, enough thimerosal-free vaccine is available to inoculate children under age 6, but that does not mean doses with thimerosal are unsafe.

New myths will inevitably arise as some of the millions of people who are inoculated against H1N1 flu suffer unrelated illnesses. Health officials will keep a close eye out for any real problems. One can only hope that the American public will understand that subsequence isn’t necessarily consequence, and not be scared away from a vaccine that can save lives.

The point of my first article was not to declare that we have nothing to fear from the H1N1 virus. To the contrary, since seasonal influenza kills more than 36,000 people in the United States alone, and between 250,000 and 500,000 people worldwide, if H1N1 is even as severe as seasonal flu, we certainly have something to fear! However, many if not most of these deaths are preventable by vaccination! A safe and effective seasonal flu vaccine is already available for everyone (I have already had my shot!) and the H1N1 vaccine, also proven safe and effective, is currently available for high-risk patients. When it is available to the general public, I will be in line to get mine! Will you?
