Did The Decision To "Pause" The JNJ Vaccine Affect The Rollout? -- April 25, 2021

Data from the CDC.

Data as reported on Sunday for the previous 24 hours. Most of these vaccines would have been given on Saturday, I assume, depending how quickly, health departments can tally same-day data.

		Total Doses Administered	Number of People Receiving At Least One Dose	Fully Vaccinated	Delta: Difference in daily doses from previous day

To the best of my knowledge, there has not been any major event or holiday for the past six weekends, including this weekend, that would affect the turnout for Covid-19 vaccinations.

To the best of my knowledge, everything but one data point is different this week. The CDC "paused" the administration of the JNJ vaccine due to safety concerns. 

In the chart above, I've hidden all weekdays for the past several weeks except for Sundays, which again, includes the Saturday vaccinations, perhaps the biggest day for vaccinations.

There was a huge jump from March 14, 2021, to March 28, 2021.

But then after that, look at the numbers. Again, these are only Sunday numbers (reflecting Saturday data, I assume).

There was a fairly linear increase from March 28, 2021, to April 18, 2021. The decision to pause the JNJ vaccine was made April 13, 2021, but by that time "all" the folks that would get their vaccination on April 18, 2021, had already made their appointments. 

But then look at the Sunday "number" reported today: lowest Sunday number in five weeks. 

It's probably "nothing." 

Sure. 

One has to remember, vaccinations are now "open" for everyone over the age of 16. It should have been a "blow-out" Sunday.  

It wasn't.
