Already, am Vaccinated.Biochemist with PhD here. I work in human In-vitro diagnostics and have since genetic testing began in the early '90s. The original test for COVID was developed on an instrument that I managed the development for.
What most people do not realize is that science is a messy process. It works because a group of people, with differing motives and agendas, all want to discover what is truth.
When things are normal, lay people do not see the process at work. That does not mean it is any less messy. In a crisis like this where everyone wants the answer RIGHT NOW (and for good reason--everyone was scared) the general public is exposed to how science works.
The CDC and the WHO, and all the local health departments (for the most part) worked to understand the virus and the epidemiology under high pressure circumstances and the microscope of moment by moment reporting. Most importantly, they also corrected anything they got wrong as soon as the evidence made that clear. The result of that is that it looked like they provided conflicting information and it looked like they changed their stances. But if you look at what each of those bodies have said over the course of the Pandemic, it is consistent with the current scientific and public health understanding at that point in time in that organization.
This process (discover, share, probe, reassess) is how science works. This is why we have all the advances that we take for granted like electric lights and vaccines. It usually does not play out under the harsh lights of political agendas and a culture war.
So, next time you get on a plane or go under anesthesia be aware that the exact same process resulted in your being able to travel safely or wake up from being sliced open and put back together. The scientific method and science works. If it had not, millions more would have died last year.
Also, get vaccinated.
