Comparatives for COVISHIELD and COVAXIN
COVISHIELD is a recombinant COVID-19 vaccine based on Viral Vector Technology, which means that it is a vaccine that uses a virus that has been genetically engineered so that it can’t cause disease, but produces Coronavirus proteins to safely generate an immune response. COVAXIN, on the other hand is a Whole-Virion inactivated CORONA Virus Vaccine, which means that it uses a form of the coronavirus that has been inactivated or weakened so it does not cause the disease, but still generates and immune response.
Total no. of doses in each vial of COVISHIELD has 10 doses of 0.5ml each, while a COVAXIN vial has 20 doses of 0.5ml each.
Shelf life of each Vaccine is 6 months and the vaccine has to be administered in 2 doses 4-weeks apart.
Both the vaccines are intramuscular injectibles.
