Two concerns may indicate under/invalid dose administered.   1) Location of injection was low side of arm & may have missed muscle.   2) Immediately after injection, clear fluid leaked out of arm, beaded up and trickled down. Nurse wiped away and it repeated leaking a second time. I asked if enough dose remained to be effective she replied "I hope so ...but I don't really know" then she left. A second nurse arrived and told us we could leave without 15 minute wait if we felt fine. I asked what to do about my leaky, off target dose, and was given phone number to report to VAERS, which I called same day, but VAERS said they only report adverse symptoms not administration problems. It was suggested I notify health dept and vaccine facility, who in turn suggested a different health dept, who in turn suggested  covid vaccine info line, who in turn suggested my PCP.  My PCP advised me to go back to clinic and get re-vaccinated.  That clinic no longer exists, so my PCP then said go to any, which I attempted, but when I did I was refused because they view me as already technically dosed, if not actually dosed.  I contacted PCP a third time, and they said I should consider myself as single dosed only, I should continue masking, social distancing etc., until I get re-vaccinated or receive a booster in the autumn.  He indicated that they would not give me a written authorization because they didn?t administer the questionable shot.  He did suggest I could lie about having received a second dose and they would give me the dose.  I thought this wrong so I gave up for a while.    I am at risk for severe complications of Covid-19 due to a long history of lung problems, lung collapse, pneumonia, irregular heartbeat, age 59, etc., and I am also a caregiver for my 91 year old mother.  Due to partially vaccinated status I must still live an isolated, masked up life. It bothers me greatly when I should have received a vaccine I could be confident of.  Recently I called Pfizer to see if perhaps they could offer information and help.   They suggested I phone CDC again about invalid/under dose vaccine administration.  I did, and CDC indicated VAERS should have taken my report when I called them, and CDC encouraged me to report it by on-line form, in hope that I may yet receive a proper second dose.   While unlikely that the shot I received on April 6th was a full dose, it is conceivable I got a partial dose.  I do not wish an overdose, but I have learned that the doses in trials were much higher without problems, and it has also been almost four months since that botched dose was given to me, and I know boosters are common in many vaccines without posing undue risk of overdose.  This must be weighed against the risks of my possibly contracting Covid-19.  It is also pertinent that I live in a anti-mask, anti-vaccine part of the world, making my exposure risks even greater.  I?m no shrinking violet, but a recent visit to my doctor?s office for skin cancer follow up was unnerving, as I was squeezed into the little exam room along with nurses, a student, and the doctor, and none wore masks and only one had been vaccinated.    I write to you to inquire if you will guide a determination and authorization in my instance of re-vaccination or booster.  Please help.
