Also, the following short video is from the initial YouTube channel I recommended above in my first post:
Myocarditis Data From Ontario Province: Specific Vaccine & Interval Between Doseshttps://www.youtube.com/watch?v=xzvos-1tiwiThe referenced article has not yet been peer-reviewed, so it should be considered in that light. It's simply additional information for each person to weigh (or, not) in their personal health decisions.
Here's some extra information I found interesting:
One of Dr. Prasad's colleagues -- Marty Makary, MD -- previously noted "...the longer you space out the intervals with any vaccine dosing regimen, the better the immunity. And, it's been studied now -- 3.5 times better with Pfizer, if you space out the two [doses] at three months apart ... and, so, that's what I recommend...and, that's what I've done for myself."
Later, in the same conversation, Dr. Zubin Damania mentions he's been suggesting people wait a bit longer than the default dosing schedule is probably good (he's been suggesting waiting 4-8 weeks), but then poses the question to Dr. Makary about
the risk of waiting longer between the first and second doses -- his concern, understandably, is whether people will be at an increased risk by being "unboosted" between doses.
To this, Dr. Makary responds: "U.K. did this, they postponed the second dose to 12 weeks, as a rationing strategy, and they had Delta during that time period and they did not see a significant influx of severe illness..." Then, Dr. Makary states that trial data from the Johnson & Johnson (J&J) vaccine shows that doses given six months apart was found to be twice as effective as doses given two months apart. He then poses the question why the FDA isn't updating their guidance, based on this information.
All of this to say that if the first and second doses of the vaccines had been spaced further apart: (1) maybe more people could have received an initial dose of a vaccine (for those who wanted it), (2) perhaps the vaccines would have been more effective, and (3) there might have been less myocarditis and pericarditis.
It's a bit late now, except for those who've not yet received any vaccines and still wishes to do so.
