The COVID-19 vaccination program is steadily progressing in Pakistan. Millions of doses have been administered across the country to date, and the Sinovac vaccine is playing a key role in the country’s mass inoculation efforts.
Read more about the Sinovac vaccine in Pakistan below.
How does the Sinovac vaccine work?
Among the available COVID-19 vaccines currently, there are four distinct types, namely, whole virus (this can again be a weakened form or inactivated coronavirus), protein subunit, nucleic acid (RNA or DNA), and viral vector.
Developed by the Chinese company Sinovac Biotech, CoronaVac, popularly known as Sinovac in Pakistan, is an inactivated COVID-19 vaccine. In simple terms, this means that the Sinovac vaccine is made from viral particles produced in a lab and then inactivated. In an inactivated state, the injected virus will not pose a threat as they are no longer capable of infecting an individual with COVID-19. The Sinovac vaccine contains proteins capable of stimulating the immune system to produce antibodies to fight COVID-19.
WHO has recommended the Sinovac-CoronaVac vaccine for use in adults 18 years and older, in a two-dose schedule with a spacing of two to four weeks.
How effective is the Sinovac Vaccine?
The scarcity and unreliability of the available scientific data for Chinese vaccines combined with the absence of peer-reviewed publications have pinpointed the efficacy rate of the Sinovac vaccine somewhat problematic.
On January 13, 2021, China-based Sinovac Biotech reported that its COVID-19 vaccine had a 50.38% efficacy in late-stage clinical trials in Brazil. The company’s clinical trials are demonstrating dramatically varying efficacy rates.
In Indonesia, a local trial demonstrated an efficacy rate of 65%, but the trial had only 1,620 participants. Turkey reported an efficacy rate of 91.25% in December 2020. Another trial in Brazil, run by Butantan Institute, reported a 78% efficacy rate in mild cases while 100% against severe and moderate infections.
As of mid-July 2021, WHO studies showed the Sinovac vaccine prevented symptomatic disease in 51% of those vaccinated and prevented severe COVID-19 and hospitalization in 100% of the studied population for adults aged 18 and older.
Are there any reported side effects?
