Scientists Are Getting Seriously Worried About Synthetic Smallpox (sciencealert.com)

An anonymous reader quotes ScienceAlert: Earlier this year, scientists published a paper describing how they pieced together segments of DNA in order to bring back a previously eradicated virus called horsepox. The paper, written by two University of Alberta researchers and the co-founder of a New York pharmaceutical company, was controversial because, as various experts told the magazine Science, someone could use a very similar process to bring back a related virus: smallpox. Smallpox, you'll recall, killed hundreds of millions of people before the World Health Organization declared it eradicated in 1980. That was the result of a long vaccination campaign — so the idea of piecing the virus back together from bits of DNA raises the specter of a horrifying pandemic.

Two journals rejected the paper before PLOS One, an open access peer-reviewed journal, published it. Critics argue that the paper not only demonstrates that you can synthesize a deadly pathogen for what Science reported was about US$100,000 in lab expenses, but even provides a slightly-too-detailed-for-comfort overview of how to do it. Some of the horsepox scientists' coworkers are still pretty upset about this. PLOS One's sister Journal, PLOS Pathogens, just published three opinion pieces about the whole flap, as well as a rebuttal by the Canadian professors. Overall, everyone's pretty polite. But you get the sense that microbiologists are really, really worried about someone reviving smallpox. MIT biochemist Kevin Esvelt, for instance, wrote on Thursday that the threat is so grim that we shouldn't even talk about it.

    Hubble went dead last week, followed by Chandra this week. Am I the only one that sees what is happening here? What's the first thing you do before you invade a country? Blind them. Take out their eyes and ears, their radar installations, etc. Then you send in the forces. With Earth effectively blinded I bet there are massive battle cruisers hidden in the asteroid belt that are even now powering up their engines and finalizing battle plans. Wake up people!!!!

    If you cripple your own products to avoid cannibalizing your existing products, your competition would do it for you.

    If it is possible to synthesize a smallpox vaccine, someone would do it. For every one publishing there are perhaps a few hundred who have had the idea occur to them. If you stigmatize it and drive it underground, when some one unleashes it, we would not even know what hit us.

    To borrow a phrase from our second amendment friends, if you outlaw synthesized smallpox only outlaws will have synthesized small pox.

    Because since 1980, there is no smallpox vaccination anymore. So everyone younger than 38 years might be affected.

    You do realize that when it was declared eradicated we stopped vaccinating against it, right?

    Anyone under the age of 30 (and probably a couple of years over, but 30 is a nice round number) is at direct risk if there's a smallpox outbreak - and if the virus was reverse-engineered it may be JUST different enough that even the people who WERE vaccinated would be at risk.

    Smallpox vaccine is made using cowpox. You do not need smallpox pathogens at all.

    Centuries before Dr Jenner made the first vaccine from cowpox, the Chinese had developed inoculation using smallpox directly. Smallpox is most deadly when it infects the lungs first, suffocating the victim before any immunity develops. So the Chinese would take scabs from pustules, crush them up, and use a needle to poke it into the skin of uninfected people. This would cause a mild form of the disease with about a 2% mortality rate, far below the 30-50% rate from airborne infections, but induce full immunity.

    The technique spread from China through the Islamic world to West Africa, and was taught to white Americans by African slaves.

    Typical practice is to first submit to the prestige journals like Science or Nature, since those give you more points towards tenure and also look better on future grant applications. Then, when that get rejected, you rewrite slightly and submit to the next tier. Lather, rinse, repeat...

    While scientist are worried about synthetic smallpox, they have not suddenly become more worried as a result of this paper. The reasons is that the DNA synthesis and virus production techniques are not new. The whole process has been published before and every step is well understood. The virus production is not even the focus of the paper, because there is nothing new about it. The story is that the small pox vaccine from vaccinia virus has some side effects. The authors of the paper decided to check if the related horse pox virus may work better as vaccine. As luck will have it the damn thing is extinct, so they made it themselves using published protocols. The horse pox virus they made seems to work well as a vaccine. The fact that making a synthetic virus was considered just a bump in the road towards some other goal should tell you how easy it is to do. The reason the paper was rejected from more prestigious journals is not that it was conveying some dangerous new information that should be suppressed. Quite the opposite, there isn't anything significantly new in the work. The reason it went to PLOS One, is that the editorial policy of this journal is to publish soundly executed research and not consider if the research discovered something new or significant.

    I was born in 1968, and just missed out on the vaccination back then. However, before going to Afghanistan in 2006, I had to get a smallpox vaccine.

    Fortunately, I had it easy since I never had it before, and it was only like 2 or 3 pokes. Those who did get it when they were little for some reason received considerably more than us first timers.

    Remember folks, if white people invent or discovered something, within a year Chinese "scholars" will find proof that they did it first.

    Nobody is claiming that. Vaccination and innoculation (variolation) are two different things. Vaccination was discovered in England in 1798. Variolation was discovered in China in the 10th century. Both of these are backed up by contemporaneous historical records.

    There are written records as early as 1721 of Americans being inoculated with variola, that specifically state that the technique was learned from Africans. That is 80 years before the cowpox vaccine was discovered in England.
