The Pfizer-BioNTech COVID-19 mRNA vaccine (Tozinameran or BNT162b2) is a medication designed to avert COVID-19. This disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The Pfizer vaccine hasn’t been approved by Food and Drug Administration (FDA) yet. The vaccine is only permitted to individuals who are 16 years old or above, under an Emergency Use Authorization (EUA).
The series of Pfizer vaccine is given in 2 doses, 3 weeks apart via an injection (0.3 mL) into the arm muscle. According to research in nearly 44,000 partakers, the Pfizer COVID-19 vaccine was 95% effective in avoiding COVID-19 during the initial 1 week after the second dose. Which means that people may not be safe from COVID-19 until at least 7 days after second dose is given.
The Pfizer COVID-19 Vaccine consist of the following ingredients: mRNA, lipids ((4-hydroxybutyl) azanediyl) bis(hexane-6,1-diyl) bis(2-hexyldecanoate), 2 [(polyethylene glycol)-2000]-N, N-ditetradecylacetamide, 1,2-Distearoyl-sn-glycero-3- phosphocholine, and cholesterol), potassium chloride, monobasic potassium phosphate, sodium chloride, dibasic sodium phosphate dihydrate, and sucrose.
In November, 2020 Dr. Albert Bourla, Pfizer Chairman and CEO stated “We are about to reach a significant milestone in our vaccine development program at a time when the world requires it most with rate of infection crossing new records, hospitals nearing over-capacity and enterprises struggling to revive. He added “Today is a great day for humanity and science. The first set of results from our Phase 3 COVID-19 vaccine trial provides the initial evidence of our vaccine’s capability to prevent COVID-19,”
There is a remote possibility that the Pfizer COVID-19 Vaccine could trigger a severe allergic reaction generally after a few minutes or one hour after receiving a dose of the Pfizer COVID-19 Vaccine.
Side effects and symptoms of a severe allergic response can include:
- Fever and headache
- injection site pain
- Increased heart rate
- Faintness and chills
- Problems with breathing
- Rashes all over the body
- Face and throat swelling
- Nausea and weakness
- Muscle or joint pain
If the symptoms get critical it is recommended to call 9-1-1, consult with your healthcare and vaccination provider or go to the nearest hospital.
