Essay: Drugmakers are applying the mRNA technology behind Covid-19 vaccines to other diseases. Can the new therapies help to cure the flu, cancer and HIV?
The vaccines that have helped billions of people around the world to protect themselves from Covid-19 were a surprise even to their manufacturers. Harnessing a new and relatively untried technology called messenger RNA, or mRNA, the vaccines were available many months and possibly even years ahead of when health experts expected safe and effective traditional vaccines to arrive.
Now scientists, governments and drugmakers are asking, what else can mRNA do? Many believe that mRNA could serve as the basis for a new generation of vaccines and drugs against a range of other diseases. Efforts in development include cancer therapies tailored to individual patients that can be assembled in a few weeks and HIV vaccines to be given periodically in lieu of current daily pills.
