Pfizer Covid-19 Vaccine Review

The pandemic has brought us many unprecedented situations, including getting a new vaccine developed in extraordinary times. Here, Drip Hydration reviews the Pfizer Covid vaccine, including risks, efficacy, and more to help you decide which vaccine is best for you.

Pfizer Covid-19 vaccine overview

Official Name: Pfizer-BioNTech Covid-19 Vaccine
Vaccine Type: Messenger RNA (mRNA) vaccine (2 doses, 3 weeks apart)

Availability

Because the pandemic meant that vaccines were developed in nontraditional circumstances, vaccines that pass rigorous testing are considered “authorized for emergency use.”

The Pfizer-BioNTech Covid-19 vaccine has been authorized for emergency use by:

  • 90 countries, including the U.S.
  • The World Health Organization (WHO)
  • Caribbean Regulatory System Emergency Use Recommendation

How it works

Messenger mRNA vaccines contain genetic material that teaches your body how to make the S protein that encases Covid-19 virus cells. This prompts the production of antibodies that now know how to recognize and fight the Covid-19 virus.

The messenger mRNA immediately begins breaking down once the body knows how to create S proteins. It does not interact with your DNA directly at any point.

Expected side effects

Just as you have symptoms when you are sick as your body fights off germs, you should expect to experience side effects. This means the vaccine is working. Most common side effects include:

  • Mild allergic reactions such as rash, itching, hives, or mild face swelling
  • Injection site pain, redness, swelling, or itching
  • Body pain, especially in the arm that received the injection
  • Chills, fatigue, fever, and other flu-like symptoms
  • Nausea, vomiting, diarrhea
  • Mind fog and swollen lymph nodes

People may experience different side effects at mild to moderate severities.

Health advisories

There are a few serious but exceptionally rare risks with the Pfizer vaccine, which we discuss below.

Severe allergic reaction

A severe allergic reaction can occur within one hour of receiving the vaccine. Your vaccination provider may request that you remain onsite for monitoring after receiving the vaccine.

Symptoms of a severe allergic reaction include:

  • Difficulty breathing and increased heart rate
  • Swelling of your face and throat
  • Severe body rash
  • Dizziness and weakness
  • Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart)

The chances of having these symptoms are very low. In most cases, this inflammation occurs a few days after receiving the second dose. In the very unlikely chance you have any of the following symptoms after receiving the vaccine, seek medical attention right away:

  • Shortness of breath
  • Chest pain
  • Sensations of fast-beating, fluttering, or pounding heart

Recent news

In June 2021, a new study emerged suggesting that the Pfizer Covid-19 vaccine is highly effective against the Delta variant of the virus. After analyzing just over 14,000 confirmed cases of the Delta variant, Pfizer’s vaccine proved 96% effective against hospitalization for those who were fully vaccinated.
