Research on Pfizer Vaccine Side Effects

Basically, Pfizer vaccines have been distributed worldwide and have been used by millions of people around the world. Launching from National Center for Immunization Research and Surveillance Australia, 245,000 people who were vaccinated reported side effects on their first dose of injection.

Then, another 140 thousand claimed to experience side effects of the Pfizer vaccine on the second dose. Then, nearly two-thirds of people reported no reaction after the first dose and 40 percent reported no reaction after the second dose.

The most common side effects include headache, muscle aches and fatigue, and these are more common after the second dose than after the first dose. These types of side effects are very similar to those reported in clinical trials and what has been defined in Pfizer vaccine product information. They occur because our immune system responds to vaccines.

Side effects will usually appear in the first 24 – 48 hours after vaccination. Side effects that last usually last less than two to three days. In addition, almost all people who experience side effects return to normal one week after vaccination.

A person experiencing Pfizer side effects can manage symptoms such as pain or fever with medications such as paracetamol or ibuprofen. However, if symptoms persist or worsen, it is necessary to immediately see a doctor.

What About Allergic Reactions?

In addition, there have been reports of anaphylaxis following the Pfizer vaccine. Anaphylaxis is an acute allergic reaction when people develop a rash, swelling of the lips and tongue, difficulty breathing and sometimes shock (low blood pressure and a fast heart rate).

Overall it is estimated that anaphylaxis occurs in about five people per one million doses of Pfizer vaccine given. Anaphylaxis almost always occurs within the first 15 minutes to half an hour after vaccination. That is why people are asked to wait in clinics after receiving the COVID-19 vaccine.

Anaphylaxis is easily treated (reversed) with injections of adrenaline by nurses and medical staff at the vaccination center and the affected person usually recovers completely. If you experience an acute allergic reaction after a vaccination, it is important to tell your doctor before getting a second dose of the same vaccine. You may be referred for an allergy specialist consultation.

Myocarditis and Pericarditis

Pfizer vaccine side effects

Recently a report from the United States and Israel spoke of the risk of myocarditis (inflammation of the heart) and pericarditis (inflammation of the lining of the heart) after the Pfizer vaccine. US Centers for Disease Control (CDC) notes these cases occur mostly in younger men (16 years and older), usually appear within days of vaccination and are more common after the second dose.

However, there is no formally established causal relationship. It is important to note that inflammation of the heart can be caused by many factors, including infection, especially from viruses or bacteria; or damage to heart tissue or muscle from autoimmune disease, medications, environmental factors, or other triggers, including, rarely, vaccines.

The Covid-19 subcommittee of the WHO Global Advisory Committee on Vaccine Safety is also reviewing this issue. They have noted that in most of the reported cases, people have recovered. The Australian Therapeutic Goods Administration, meanwhile, continues to monitor myocarditis and pericarditis as “adverse events of particular interest”. Rigorous studies comparing the number of cases of myocarditis in vaccinated and unvaccinated populations are underway in countries such as Israel, the United Kingdom, and the United States to assess whether there is an association between myocarditis and the Pfizer vaccine.

While there are side effects to the Pfizer vaccine, keep in mind that this vaccine has far greater benefits than side effects. This vaccine has been shown to have reduced deaths and hospitalizations due to Covid-19. Therefore, there is no need to hesitate anymore for a complete vaccination, OK? Parents!
