VALNEVA VACCINE

About:

• VLA2001 is an inactivated, adjuvanted vaccine. This means that it delivers the whole Sars-CoV-2 virus in an inactivated form. The virus is killed using chemicals, heat, or radiation. The dead virus cannot infect us but can still trigger an immune response.
  
  
• Polio and flu vaccines are common examples of inactivated vaccines. India’s Covaxin is also an inactivated vaccine.
  
  

Comparison with Other vaccines

• Currently, none of the vaccines in the UK – Moderna, Oxford/AstraZeneca, – are inactivated vaccines. Moderna and Pfizer/BioNTech are mRNA vaccines. They contain the code of the SARS-CoV-2 spike protein and once inside the body teach our body to produce the spike protein.
  
  
• Our immune system recognises this and initiates an immune response against Covid-19.
  
  
• Oxford/AstraZeneca vaccine delivers the code of the SARS-CoV-2 spike protein using a carrier – another virus called adenovirus.
