Antisera are blood serum excessive in antibodies towards particular antigens and are injected in people to assist kickstart the immune system to combat particular infections. The pre-print model of the research relating to the event of the equine antisera has been posted on Research Square platform. “The study provides evidence of the potential of generating highly purified F(ab’)2 from equines against SARS-CoV-2 that can demonstrate consistent and high neutralization activity. Further, in-vivo testing for efficacy of this indigenously developed, cost effective product will pave the way to clinical evaluation. Additionally, being a donor independent method, this may prove as an efficient alternative to convalescent plasma for treatment of Covid-19 patients,” the research paper mentioned.
Earlier such measures have been used for controlling a number of viral and bacterial infections. “Although, plasma recovered from patients experiencing Covid-19 could serve similar purpose, the profile of antibodies, their efficacy and concentration keep varying from one patient to another and therefore make it an unreliable clinical tool for patient management,” the ICMR mentioned in a tweet. “Standardization achievable through equine sera based treatment modality thus stands out as yet another remarkable public health initiative supported by ICMR in the time of Covid-19,” it mentioned.
As a part of the research, 10 wholesome horses have been immunized with inactivated SARS-CoV-2 virus and after 21 days of immunization, plasma samples have been examined. The outcomes of the plasma samples indicated presence of indicated the presence of SARS-Co-V2 particular IgG antibodies as detected in ELISA with neutralizing capability. The research has not but been peer-reviewed.
