Not much at this point.
Be cautious about reports of infections — and now, a few deaths — among vaccinated people. This subject is ripe for exploitation by anti-vaxxers and others with agendas, so stick with reliable (preferably official) sources, and keep in mind that even in verified cases there are potential loose ends, such as whether the victims were already infected before being vaccinated (which, as we shall see below, is a factor in those reported deaths).
That said, experts acknowledge it’s possible to get infected after being vaccinated, although all three vaccines approved for use in the United States are said to be 100% effective at preventing hospitalizations and deaths. The question is whether that’s in question, following news reports from Michigan (currently an infection “hot zone”) of 246 cases and 3 deaths among fully vaccinated people. I’ll get into those reports shortly.
On the first point, whether you can still get infected, the mRNA vaccines (Pfizer and Moderna) are said to be 95% effective at preventing infection. This means you still have a 5% chance of getting Covid-19 from exposure after being vaccinated. (These are called “breakthrough” cases, i.e. the virus “breaks through” the antibody protection created by the vaccine, like British tanks crashing through German trenches in 1918.) But the overall risk of infection is much lower; and on a vast public scale, that can suppress contagion to where the virus dies out or exists only in isolated pockets.
That’s a huge deal in terms of putting the pandemic behind us, and elevates getting vaccinated from individual choice to citizen duty. (As for anti-vaxxers — who are predominantly Republican men, read that story here — there are draft dodgers in every war, but no one calls them patriots. Anti-vaxxers are antisocial, not patriotic.)
Now for the Michigan reports. The Detroit Free Press reported on Tuesday, April 6, 2021:
“State health officials say 246 fully vaccinated Michiganders contracted coronavirus from January to March, and three have died.”
