The difference between the Pfizer vaccine and the Sinovac vaccine
In light of the pandemic of the Corona virus (Covid-19) in which the world is living today, vaccines for this virus have appeared, and after the production of several vaccines against the Corona virus, people have become confused and arguing for the best vaccine.
In this article, we will talk about two types of vaccines used in the face of this virus, and we will devote ourselves to knowing the most widespread and fastest of these vaccines, namely:
1- The German-American Pfizer vaccine for biotechnology.
2- Chinese Sinovac vaccine.
This is in terms of several points that can be addressed by raising the most important questions that can be repeated among people:
What is the difference between the German-American Pfizer vaccine and the Chinese Sinovac vaccine!
In terms of the method adopted for both of them in the injection?
What are the categories that can get these vaccines?
And clarify the side effects that occur from both vaccines? Is there a way to avoid these symptoms!

First, the difference between the Pfizer vaccine and the Sinovac vaccine in terms of the method adopted in vaccination or injection
1- (American Pfizer Vaccine)
According to the World Health Organization (WHO), the Pfizer vaccine, which is considered an anti-coronavirus, which was developed by Pfizer in cooperation with the Biontech company, is based on a newer technology (that uses the genetic sequence of the nucleic acids of the virus to stimulate the body to produce antibodies that work to fight the virus) and is considered to be The first vaccine authorized for use in the United States of America, and it was announced in the most difficult and dangerous times that the country is going through, which is witnessing a significant increase in the number of infected people, and this led to the introduction of vaccinations and injecting people with the vaccine to help reduce the rapid spread of the virus, as vaccinations began for those who work in Medical fields and people who stay in places of care for a long time, such as places of care for elderly people, then doses will be provided to other groups of people
2- (Chinese Sinovac vaccine)
While the Chinese Sinovac vaccine was based on the traditional method (which contains viral particles that are very small parts of this genetic material of the virus, the body then secretes a specific protein that the immune system recognizes and defends itself against the virus) and the vaccine was presented in a number of countries The results of the vaccine experiments differed on the people who received the vaccine, as some Turkish researchers said that the vaccine has an effectiveness rate of about 91.25 percent, while Indonesia, which used the vaccine, announced that its effectiveness is about 65.3 percent, and these results are considered temporary results.
Second, the groups that can receive the Pfizer vaccine
From the results, it is clear that the Pfizer vaccine achieved a 95% success rate, and it can be received by all groups from 16 years of age to over. Number of doses Two doses are taken and there is a period of three weeks between each dose and the other.
(People who can receive the Sinovac vaccine)
All categories starting from 18 years old and above. The number of doses is two doses from 14 to 28 days.
We note that there are some groups that are excluded and cannot receive any of the Pfizer or Sinovac vaccines, including:
1- Children under the age of 16
2- Pregnant or breastfeeding women
3- Categories that have severe sensitivity to any of the vaccine components
4- People with chronic diseases or people who have undergone major operations such as kidney transplantation or liver transplantation…. etc
5-Immune patients People who have a deficiency of immunity and their immunity is affected by anything that enters their bodies
Third side effects of both vaccines:
It is natural that there are some side effects of a vaccine or treatment, but how effective are these side effects? Are they dangerous to our lives and need medical intervention, or are they simple and go away with the passage of time?
In fact, all medical authorities, including the Egyptian Ministry of Health, have clarified that the expected side effects of the Corona virus vaccine are in a large proportion, natural and simple symptoms that appear clearly, especially after the second dose, and they can disappear quickly and should not last more than a week. Among these symptoms:
1- Inflammation and swelling at the injection site
2- Feeling of headache and fatigue
3- Feeling pain in the muscles
It also indicated that women are more susceptible to these side effects of the vaccine than men.
People who have been infected with the Coronavirus may be more likely to develop side effects and be more difficult than those who have not had the virus before.
Fourth, which of the two vaccines is better, is the German-American Pfizer vaccine or the Chinese Sinovac vaccine?
There was a great debate about which of the two vaccines is better, and this issue must be resolved and a clear answer can be found, as we can say that there is no vaccine better than a vaccine.
Both Pfizer and Sinovac vaccines are considered vaccines approved by the World Health Organization, but each of the two vaccines differs according to efficacy rates, as we mentioned before that the American Pfizer vaccine is 95% effective, while the Sinovac vaccine is effective between 65 and 91%. It is also possible to look at the expected side effects of both vaccines, and this depends on the concerned group that is using the vaccine.
