All you need to know about Covishield
How does Covishield act?
This is a monovalent vaccine. It contains the SARS – CoV – 2 spike ( S ) glycoprotein along with a tissue plasminogen activator. Following vaccination, the S glycoprotein helps to release genes that are transported to the cell’s nucleus. These changes ultimately lead to the stimulation of the neutralizing antibodies and cellular immune response.
What is the dosage frequency of Covishield?
The medicine is administered by two 0.5 ml doses injected intramuscularly into the muscle of the upper arm. It will help if you take the second dose four to eight weeks after the first shot.
Is it effective?
The vaccine is 76.0 % effective in preventing symptoms of COVID. The effects begin at 22 days following the first dose. This increases up to 81.3 % when the second dose is given.
