In the search to find a vaccine to put an end to the coronavirus pandemic, some scientists worry that President Trump's"Operation Warp Speed" is missing out on tried and true vaccine technologies that have over and over again resulted in proven winners.
The Trump administration is not funding vaccine approaches that have been used for more than 50 years, including for current vaccines against hepatitis, flu, polio, and rabies. Vaccine experts want the FDA to commit to 30,000 people in Covid-19 vaccine trials Instead, the United States is investing up to more than $2 billion in newer approaches that are promising, but for the most part, have not resulted in approved vaccines, much less vaccines with long track records.
hina has taken a very different approach than the US, with four of its five vaccines in clinical trials using the older approach. But the director of the US National Institutes of Health says there's a"need for speed," and the older approach takes"considerably longer" to develop. "We have no time to waste," Dr. Francis Collins told CNN. Collins said he also has safety concerns about the older approach favored by the Chinese.
And if the first US vaccine to come on the market is only somewhat effective, or has safety concerns, some fear the American public won't believe public health authorities if they say to try the next vaccine that comes along. The scientific community will"lose some credibility if that's the way it plays out," said Offit, the University of Pennsylvania vaccine specialist.
