Perspective about Convalescent plasma technique regarding past
CoV-epidemic
SARS represents first transmissible pandemic disease of Coronaviruses.
During its outbreak, 176 patients who were suffered from this viral
infection and treated with convalescent plasma, their SARS-specific
antibodies were collected and maintained for an average of two years.
These antibodies were monitored regularly showing their percentage
largely continued to increase till two years showing the immune response
of these people as maintained. Initially, after two years their IgG
antibodies percentage started reducing, and after three years, these
convalescent population show no SARS-CoV specific-IgG antibodies. It
indicated that these people are again susceptible to SARS infection (Wu
et al., 2007). So, based on these findings, we can predict that duration
of current ongoing convalescent plasma technique to treat COVID-19 in
Pakistan will not be lifelong. Government with the help of scientists
should think of some alternative lifelong curative strategy. (Wu et al.,
2007).
