The corona virus contains a spike (S) protein on its surface which uses to enter into cells, it is the primary target for already developed vaccines against this disease.
Why spike protein is important to fight against corona virus?
The spike (S) protein is a trans-membrane protein present on the viral envelope, which is required to enter the cell by binding to the ACE2 receptor.
All vaccines developed until now are based on boosting the immune system to develop antibodies against specific antigens present in the S protein.
The main classes of vaccines to fight against this virus include:
- Viral vector vaccines (e.g., AstraZeneca)
- Messenger RNA vaccines (e.g., Pfizer)
- Attenuated vaccines (e.g., Sinopharm)
In conclusion, corona virus contains a spike S protein that is the primary target for already developed vaccines against this disease.
