Covishield produces extra antibodies with larger seropositivity price than Covaxin

A preliminary examine by Coronavirus Vaccine-induced Antibody Titre (COVAT) has acknowledged Covishield vaccine produced extra antibodies than Covaxin. The examine, involving healthcare staff (HCW) who’ve obtained each doses of both of the 2 vaccines, additionally stated seropositivity charges to anti-spike antibody have been considerably larger in Covishield recipients as in comparison with Covaxin after the primary dose.

The examine is a preprint and has not been peer-reviewed, so shouldn’t be used to information medical follow.

It stated that each vaccines– Covishield and Covaxin– elicited a very good response after two doses, however seropositivity price and median anti-spike antibody have been considerably larger in Covishield.

“Amongst the 552 HCW (325 Male, 227 Feminine), 456 and 96 obtained the primary dose of Covishield and Covaxin respectively. General, 79.three per cent confirmed seropositivity after the primary dose. Responder price and median (IQR) rise in anti-spike antibody have been considerably larger in Covishield vs. Covaxin recipient (86.eight vs. 43.eight per cent; 61.5 vs. 6 AU/ml; each p<zero.001),” the examine stated.

The examine concerned these healthcare staff who’ve been administered both of the 2 vaccines Covishield and Covaxin and are with or with out previous historical past of SARS-CoV-2 an infection.

“This ongoing, Pan-India, Cross-sectional, Coronavirus Vaccine-induced Antibody Titre (COVAT) examine is being performed amongst HCW, with or with out previous historical past of SARS-CoV-2 an infection. SARS-CoV-2 anti-spike binding antibody is being assessed quantitatively at 4 time factors¬†between 21 days or extra after the primary dose to six months after the second dose,” the examine stated.

Nonetheless, the conclusion of the examine stated that each the vaccines have proven elicited good immune response.

“Whereas each vaccines elicited immune response, seropositivity charges to anti-spike antibody have been considerably larger in Covishield recipient in comparison with Covaxin after the primary dose. Ongoing COVAT examine will additional enlighten the immune response between two vaccines after the second dose,” it stated.
