I don’t think the editors of the Washington Post quite appreciate the present situation with respect to the AstraZeneca vaccine:
More than a dozen countries, including Germany, France, Italy and Spain, temporarily suspended the AstraZeneca rollout after reports last week that some people in Denmark and Norway who got a dose had developed blood clots. There was no evidence that the shot caused them. The company says that out of 17 million doses given in Britain and Europe as of March 8, there were only 37 incidents of blood clots, less than what would be expected to occur naturally in a population of this size. German regulators, worried about seven cases of severe cerebral venous thrombosis that occurred within four to 16 days after the vaccine, including three persons who died, said the rate was above what would be expected.
I wonder how the editors think that evidence is accumulated or what constitutes proof in a medical setting? Offhand I’d case that you start with correlation and the Germans, French, etc. have that.
Let’s recap:
- Questions were raised about the AZ vaccines clinical testing.
- After receiving the vaccine some people experienced blood clots, in a few cases leading to death.
- Norway and Denmark suspended the use of the AZ vaccine.
- Then a few other countries like Bulgaria and Ireland did the same thing.
- Then all of the major European countries followed suit.
What’s wrong with that?
The editors conclude:
A lesson of this moment is that no medicine is 100 percent safe and effective. The flu vaccine must be reformulated every year to cope with mutations. Despite widespread use of the measles vaccine, outbreaks still occur.
Europe has an enormous job ahead to vaccinate tens of millions of people. Everyone should expect speed bumps, be vigilant for serious problems — but avoid panic.
Can’t the same lesson be learned from COVID-19 itself? There is no such thing as perfect safety. A year into the COVID-19 pandemic about 9% of the U. S. population has been diagnosed as having contracted the disease (estimates are higher) and of those 1.8% have died. Not to diminish the seriousness of the disease but that’s still a small risk. There may also be a small risk in getting the AZ vaccine. We’re confronted with the problem of comparing two small risks. Now add that there are other alternative vaccines (at this point Pfizer, Moderna, and Johnson & Johnson) none of which have comparable reports. The actions of France, Germany, etc. don’t seem that outrageous to me under the circumstances.
