Old vaccines, and the search for new vaccines

I am a strict constructionist on the necessity of vaccines. Since Edward Jenner produced a vaccine for smallpox in 1799, millions, perhaps billions of lives have been saved by vaccines. The search for new vaccines will never end because infectious organisms constantly evolve. Influenza viruses evolve to escape last year’s immune defenses. We have yet to master HIV with a vaccine. 

Treating opioid abuse: costly research is well worth it

We like every catastrophe to have a single cause because a villain, especially one that had been identified, is a satisfying thing. In the case of opioid use disorder, one villain is Purdue Pharma, makers of OxyContin, a powerful pain reliever and euphoric that the company claimed was not addictive. It is addictive, but so are   enormous profits. Purdue is getting its slow-drip punishment, in the form of massive lawsuits, and it faces insolvency.

Does Prevagen help in reducing memory loss?

You may have seen the ad for Prevagen during morning news shows or between innings of a Red Sox game: a video of a pulsating jellyfish, whose nervous system glows blue. The substance that provides the blue glow is protein called apoaequorin and it is very well studied.
