Two Key Questions About Bird Flu Vaccines
Summary
A government-funded study reveals that exceptionally high doses of an avian influenza vaccine, provided by Sanofi-Aventis, are necessary to trigger an immune response effective against the virus. This study found that 54% of volunteers required two doses of 90 micrograms each, administered 28 days apart, while a typical flu shot contains just 15 micrograms.
Given these findings, the current U.S. vaccine stockpile could only cover about four million people, as per Dr. Anthony Fauci, Director of the National Institute of Allergy & Infectious Diseases.
Issues with Current Vaccine Production
The challenge isn't merely the dosage?"it’s also about production methods. Flu vaccines are made using a 50-year-old technique involving hen's eggs. Automated systems inject eggs, which then incubate for 11 days to grow viruses that are eventually killed and bottled. Producing millions of doses this way can take around six months.
Concerns About Egg-Based Production
A critical question arises: if we use chicken eggs to incubate an H5N1 virus, how do we ensure the virus won't destroy the eggs? Given that H5N1 already kills chickens, it’s reasonable to question if it could also affect eggs. Sanofi-Aventis is investing $150 million in a new facility, betting that the virus won’t harm the eggs. Notably, these eggs must be ordered months in advance for this outdated process.
Moreover, sourcing enough egg-laying chickens poses another challenge, especially given the widespread culling of chickens globally. A potential outbreak could devastate U.S. chicken farms quickly.
Emerging Vaccine Technologies
Fortunately, new vaccine technologies are on the horizon. Cell-based vaccines use large vats of living cells, like dog kidney cells, which are then inoculated with the virus. Companies in Holland and Germany are already exploring this technology, but it won't be widely available for years. The FDA must thoroughly evaluate the method before approving any equipment for import to the U.S.
The Urgency of Vaccine Research
It’s clear the U.S. may have waited too long to advance vaccine research. H5N1 isn’t pausing; it continues to mutate, increasing its potential for human-to-human transmission. Dr. Robert Webster, a renowned expert, describes H5N1 as "the most frightening virus I've ever seen in 40 years of research."
Conclusion
If you’re relying on a vaccine to protect against H5N1 (Avian Influenza), think again. Many questions remain unanswered, and the risks are significant.
