I don't think that can be answered with any authority at this point, again...because there is a lack of data due to a lack to time studying it in humans.
Regarding the flu vaccine, most health professionals ask if your currently sick with certain symptoms before administering the shot because they generally don't want to stress your already stressed immune system. If you've had it, but are over it, they will generally administer the shot with the thinking that...since the flu vaccine can protect against several strains, it still might be beneficial.
Another question regarding this vaccine (Pfizer's) would be...since this vaccine requires 2 shots, how precise of a timeline do those shots need to be given?
We're told they need to be given a few weeks apart. That doesn't sound very precise.
Many patients are notorious for not taking their medication/shots/treatment properly.
What if someone gets the shot a few days after the optimal time? Do they have partial immunity? What does that look like in terms of disease prevention? Do they need a 3rd shot? What is the safety profile of a 3rd shot, if any? Or, would they have to go with whatever partial immunity they may have and wait X number of months before starting all over?
Another question...since this vaccine has very specific storage requirements that are difficult for most places that would be administering it, we're told this vaccine must be used within 4 or 5 days once kept at "normal refrigeration" temperatures.
Again, that's not very specific.
Have they run trials and studied what happens if many people are given a 1st dose vaccine that's been refrigerated for 5 days...but then comes back in a few weeks and is given a vaccine that is recently brought out of deep freeze and refrigerated for less than a day? Meaning, their 1st dose was not fresh and their 2nd dose was. How about the reverse of that scenario?
Thank you so much for your informative reply. There is certainly a lot to consider. I intend to wait before I consider getting the vaccine even though at age 71 I’m considered at risk to some extent. There is just too much uncertainty at this point.
