Trial summary

In most parts of the world, mRNA vaccines were used to provide protection to population against COVID 19. However, in some countries, including Pakistan, traditional viral vaccines named as Sinovac and Sinopharm were used for mass level immunization. Read more about this study

About this study

Official title: Booster Effect of mRNA Vaccine After Complete Vaccination With Sinos: an Observational Study

In most parts of the world, mRNA vaccines were used to provide protection to population against COVID 19. However, in some countries, including Pakistan, traditional viral vaccines named as Sinovac and Sinopharm were used for mass level immunization. Though these vaccines were approved by WHO, their efficacy had been questioned.

Now after recommendation of booster doses, we aim to see the effect of mRNA vaccine as a booster dose after Sinovac and Sinopharm in terms of antibody response. (IgG RBD SARS CoV2)

In most parts of the world, mRNA vaccines were used to provide protection to population against COVID 19. However, in some countries, including Pakistan, traditional viral vaccines named as Sinovac and Sinopharm were used for mass level immunization. Though these vaccines were approved by WHO, their efficacy had been questioned.

Now after recommendation of booster doses, we aim to see the effect of mRNA vaccine (BNT162b2, pfizer) as a booster dose after Sinovac and Sinopharm in terms of antibody response. (IgG RBD SARS CoV2).

The antobody IgG RBD levels will be checked before the booster dose and then after 3 weeks of the booster.

Being tested
booster vaccine for COVID 19

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • booster vaccine for COVID 19Biological

    The effect of Booster vaccine will be seen in participants in terms of antibody response IgG

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. IgG RBD levels

    to see the effect of booster vaccine after 3 weeks in terms of IgG RBD

    Measured: after 3 weeks of booster vaccine dose

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

IgG RBD levels (time frame: after 3 weeks of booster vaccine dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
