Unlike older vaccines (such as polio vaccine) which generally used weakened or killed whole virus particles (and which occasionally produced infectious cases, due to the virus not being as weak or dead as intended), this vaccine contains no whole virus particles and thus cannot result in an infectious case. It contains RNA that cause the patient's cells to emit proteins normally produced by the viral infection (which can then be recognized by the immune system), but contains none of the genetic material required to produce standalone infectious virus particles. This is a new thing; these will the first vaccines using this technology to be approved. The chairman likely isn't worried about the vaccine itself producing infections, but rather does not know whether a vaccinated patient might also develop an active infection before the vaccine takes effect.

Not that I agree with GPs concern, but this comment doesn't address it whatsoever.

  It absolutely does address it. The Pfizer chairman is saying he doesn't know whether you can get a spreadable COVID-19 infection after the vaccine has been administered, but before it takes full effect. That's an entirely different thing from the vaccination CAUSING an infectious case of COVID-19.

There is absolutely 0% chance I'll be letting that anywhere near my family. And I was a biomedical scientist formerly. Over my dead body (one way or another).

    >Could we maybe avoid putting others at risk? I agree. Let's not inject people with experimental vaccines rushed to market under significant political pressure. Let's not pressure strangers' decisions either way. Far more money in this career path. I've made more some days writing junk code than I ever made in a year in a lab. It's easy to see why some scientists might be incentivised by external factors...

      > Let's not inject people with experimental vaccines rushed to market under significant political pressure. I'm less worried about political pressure, and more worried about the very real pressure being applied by the virus. There have been tests which have been safe thus far, and in my opinion there is less risk in moving forward with testing and distribution of the vaccines then not doing so. > Let's not pressure strangers' decisions either way. I'm of mixed feelings on this, and my overall opinion is that it depends on who all is able to take the vaccine. If there are few restrictions, maybe this would be okay. However, if there are enough restrictions that there will be a sizable number of people who cannot take it, we need to get as many as possible out to try to protect them. [Edit: This is referring to legal pressure. I am of the opinion that it is not unreasonable to encourage others to take vaccines if they are able.] > Far more money in this career path. I've made more some days writing junk code than I ever made in a year in a lab. It's easy to see why some scientists might be incentivised by external factors... First of all, I'd like to apologize for my ad hominem attack earlier. That was uncalled for. Second, I find it hard to believe that scientists would be pushed to do something actually dangerous on this sort of scale, and like I said earlier, I find the idea of not combating the virus more dangerous then moving forward as quickly with vaccines as can be safely done. However, it's quite possible that I just have too much faith left in humanity.
