Pfizer and Moderna Vaccines Likely to Produce Lasting Immunity

Recommended Posts

We are enjoying being in a high vaccine state but will revert back to semi-isolation come fall when we return to Mesa.   Luckily, there are lots of restaurants that have outdoor seating in Arizona, especially Oct-Nov and Feb-March time frames.   And we can always hope that more people in Arizona become vaccinated.

Pfizer is proposing a 3rd dose to help with the delta variance.

To be specific they are asking the FDA for the go ahead to do clinical trials to see if the booster shot will improve the titer level (amount of Covid-19 antibodies) circulating relative to those who don't get a third booster shot.  If trials do not show an improvement in level (which means 1/2 of the trial participants would get placebos and not the 3rd booster shot) then a booster will not be offered.  The trial would also show if reactions to a 3rd shot are likely to be stronger than with the second shot.    It is tricky to figure out when a booster is needed and what the likely reactions will be.

UPDATE - so now they are asking for an EUA (emergency use authorization) to go ahead and begin a 3rd dose. Guess they information they are getting out of Israel have tipped in favor of getting the EUA while other trials of combinations are going on.   

Of course there are questions to be answered, specifically, will the 3rd dose be free, or will we have to pay, and how will we go about getting the 3rd dose to everyone, when they are trying to get 1st and 2nd doses in arms across the country.     What fun it will be trying to figure out where to get boosters this fall while traveling.   Of course, since it is only 1 shot, no worry about being able to get the second before leaving an area.
