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).
