Is the Chinese vaccine Sinopharm safe and effective?

Data on vaccine quality, safety, and efficacy have been carefully evaluated by; several countries.

The results showed that the efficacy of Sinopharm after two doses given 3 to 4 weeks apart was up to 79% against infections with severe symptoms.

Sinopharm vaccine versus Pfizer vaccine

The Sinopharm vaccine was manufactured by; a Chinese pharmaceutical company located in Beijing.

The Chinese vaccine is considered a traditional vaccine.

It consists of inactivated parts of the Coronavirus, with an adjuvant found in many other vaccines such as; rabies and polio.

Its action depends on prompting the immune system to produce antibodies to the entire Coronavirus without causing an infection.

On the other hand, the Pfizer vaccine action depends on generating antibodies against the Coronavirus genetic material (mRNA).

The Sinopharm vaccine is the best choice for developing countries.

It can be stored at a temperature ranging from 2 to 8 degrees Celsius

Moreover, there is a sticker on the packaging that changes color if it becomes unusable.

While, the Pfizer vaccine needs a temperature of 70 degrees below zero to remain stable, which is hard to provide in all places.


Who should take the vaccine?

Priority should be given to medical staff members exposed to infection during their work and the elderly, especially those with chronic diseases.

Also, people with HIV since they’re more prone to infections.

People previously infected with Coronavirus can also take the vaccine but after six months of recovery.
