Evaluation of Clinical and Antibody Response to Covid-19 Vaccination Strategy in TBRI, Egypt
Studieöversikt
Detaljerad beskrivning
SARS-CoV-2 has been in the human population for more than a year now, causing severe disease in some and resulting in a pandemic that continues to put severe strain on economies and healthcare infrastructures worldwide. Vaccination is considered as one of the greatest successes in medical history. Based on prior experience with the development of SARS-CoV vaccines, all COVID-19 vaccines must be subjected to the tests for protective effects and harmful risks derived from antibody-dependent enhancement that may contribute to augmented infectivity and/or eosinophilic infiltration. The SARS-CoV-2 vaccine is now being developed urgently in several different ways.
In the UK, the first three vaccines have emergency use authorization, and a national rollout is in progress. Many other countries are also instigating large scale vaccination programmes. Assessment of the safety and efficacy of vaccines against the severe acute respiratory syndrome coronavirus (SARS-CoV-2) in different populations is essential .
The UK government recently decided to extend the interval between the first dose of the Pfizer BioNTech and AstraZeneca COVID-19 vaccines from 3 weeks to 12 weeks to maximise the number of people receiving the initial dose, despite the trials only providing vaccine efficacy data based on a schedule of 21 days between doses.
Many reports were raised claiming Astrazenica vaccine for the development of vascular thrombosis and studies are not finalized regarding this issue .
China is regarded as one of the world's leading countries in SARS-CoV-2 vaccine development, up to date the last inactivated vaccine international clinical (Phase III) trial was launched in the United Arab Emirates by Sinopharm China National Biotec Group (CNBG).The ability to track and trace vaccines through the vaccine supply chain down to persons vaccinated has to be enhanced.

Deltagargrupp / Arm |
Intervention / Behandling |
|---|---|
|
Övrig: 1- Before vaccination:
To detect:
|
COVID-19 vaccines should be administered by intramuscular (IM) injection, preferably into the deltoid muscle of the upper arm.
Individuals who have minimal muscle mass in the deltoid area of the upper arm, or a particular reason to avoid immunization in the deltoid muscle, can be given their vaccine in the vastuslateralis muscle in the thigh if necessary.
|
|
Övrig: 2-7 days after the first dose
Measuring D-dimer

|
|
Övrig: 3-Before the second dose:
To detect IgG and IgM To detect the level of Covid-19 Ig G antibodies titer in the blood, Quantitative Ig G titer should be measured.
To detect the response of the immune system to the vaccine.

to develop IgG antibody
Tidsram: seven to ten days

These antibodies indicate that you may have had COVID 19 in the recent past and have developed antibodies that may protect you from future infection.
It is unknown at this point how much protectionantibodies might provide against reinfection.
This group of individuals should receive the vaccine.
Quantitative Ig G titer should be measured.
