A vaccine is a type of medicine designed to protect against infectious diseases by introducing the body’s immune system to a harmful germ in a safe way.
Vaccines stimulate the body’s own protective immune responses.
If a person is infected with a harmful germ, the immune system can quickly prevent the infection from spreading within the body and causing disease.
In this way, vaccines mimic natural infection but without actually causing the person to become sick.
The whole virus is killed with a chemical so that the virus can no longer multiply and cause disease.
This inactivated virus is then used to make the vaccine.
This is the same approach used to make the flu vaccine,inactivated polio or hepatitis A vaccines.
The vaccine is certified halal by Halal Certification Services Chongqing (HCS) (Certificate number:2019ILC/L-056052820) which is recognized by JAKIM as foreign halal certification body or authority
From previous studies, this vaccine can cause common reactions such as pain, swelling, redness and itching at the injection site, fatigue, fever, diarrhea and other side effects.
However, they are usually temporary and often treatable.
The long term safety profile of the vaccine is unknown and this study attempt to study the vaccine safety profile up to one year.
