The reporter is the patient.  A 75-year-old female patient received BNT162b2 (BNT162B2), as dose 1, single (Batch/Lot number: unknown), as dose 2, single (Batch/Lot number: unknown), as dose 3 (booster), single (Batch/Lot number: unknown) and as dose 4 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. The following information was reported: DRUG INEFFECTIVE (medically significant), COVID-19 (medically significant) all with onset 07Aug2022, outcome "recovering" and all described as "diagnosed with COVID-19"; BODY HEIGHT DECREASED (non-serious), outcome "unknown", described as "shrunk a little". The patient underwent the following laboratory tests and procedures: SARS-CoV-2 test: (07Aug2022) Positive, notes: she was diagnosed with COVID-19 morning of 07Aug2022. Therapeutic measures were taken as a result of drug ineffective, covid-19.  Additional information: She was diagnosed with COVID-19 last Sunday morning and she received a box of Paxlovid pill and unfortunately stopped taking Paxlovid pill after 4 days. She wanted to make sure if it is ok to stop Paxlovid pill after 4 days. She is already okay. Caller initially clarified that she was diagnosed with COVID-19 morning of 07Aug2022 and started Paxlovid therapy that night. She initially clarified that she did not stop taking Paxlovid after 4 days, that the box of Paxlovid she received only contained 4 day's worth of Paxlovid tablets. Because of that she will not be able to take tonight's dose or the full 5 day course. She called to ask if it is ok to only take 4 day's worth; or if she does get the missing pills on a different day like tomorrow or saturday can she continue taking it and if so does she just finish the 1 pack or should she start all over? At the end of this report she clarified that her husband found the missing pack of Paxlovid tablets, that they had apparently fallen out of the box and was put in their junk drawer; so she did not actually need to report or question anything at this time and chose to end the call. Paxlovid is a miracle drug, she started it on 07Aug2022 and by 08Aug2022 she felt good, she feels fantastic, the Paxlovid worked after 2 days and she is not a good pill taker. Paxlovid is a miracle drug, very powerful. She mentioned unrelated information that her husband and she both took both shots and boosters, that she did Pfizer and her husband did Moderna.
