What is The Difference Between pfizer Coved-19 Vaccine and Senopharm Vaccine?

Vaccine is a substance inserted in the body to stimulate secretion of antibodies to protect you from infections either by using killed or inactivated viruses or weakened viruses.

As the world continues its battle against the COVID-19 pandemic, multiple vaccines have been developed and distributed globally. Among these, the Pfizer-BioNTech and Sinopharm have gained prominence.

The benefits of coved-19:

No one knows what will be the effect of the virus if he is injured. We find people are injured with no symptoms and others with mild or sever symptoms so these has two benefits:

• Protect you from being infected.
• Protect you from the severe symptoms.

What does the pfizer consist of?

It consists of 4 main compositions:

• The genome of coronavirus mRNA.
• Small particles that cover the mRNA and help in penetrating the human body such as: polyethylene glycol (which may cause some side effects of the vaccine) and cholesterol.
• Some salts that make the acidity of vaccine close to the human body’s acidity such as: Potassium chloride, sodium chloride, monobasic potassium phosphate, basic sodium phosphate dihydrate.
• Sucrose which prevents sticking of these components in low temperatures, It has no preservatives.

May the vaccine cause an infection with Covid-19?

No, but it took several weeks for the vaccine to be effective and you should take the second dose before, so you are susceptible to infection during this period. If the infection occurs it might be due to contact with an infected person.

Are the new vaccines safe for children?

The scientists don’t approve using the vaccines for children yet. The approved age of the pfizer vaccine starts from 16 years old while moderna approved age starts from 18 years old.

What are the side effects of vaccines?

Most have mild side effects such as: fever, headache, feeling fatigue, redness and swelling at the site of injection. These symptoms disappear within 1-3 days if it lasts for a longer period you should ask the doctor.

Considerations for Choosing

1. Efficacy: While the Pfizer boasts higher efficacy rates in preventing COVID-19 infection, the Sinopharm still offers substantial protection, especially against severe illness. The choice may depend on the prevalence of COVID-19 variants in the region.

2. Availability: Accessibility is a crucial factor. The availability of either vaccine may vary by location, and individuals may receive the vaccine that is readily accessible to them.

3. Booster Shots: Consideration of booster shots may influence the choice . Pfizer has been widely used for booster doses, but the availability of Sinopharm boosters may vary.

4. Underlying Health Conditions: Individuals with specific health conditions may consult healthcare professionals for vaccine recommendations tailored to their needs.

5. Travel Considerations: Some countries may have specific entry requirements, which could influence the choice of vaccine for international travel.

6. Age and Eligibility:  eligibility and recommendations may vary by age group and risk factors, so individuals should follow local health guidelines.

Both the Pfizer-BioNTech and Sinopharm  have played significant roles in the global effort to combat COVID-19 in 2023. The choice between them depends on various factors, including efficacy, safety, availability, and individual circumstances. Ultimately, vaccination remains a crucial tool in controlling the spread of the virus and reducing the impact of the pandemic. Individuals are encouraged to consult healthcare professionals and follow local health guidelines when making vaccination decisions.
