    After all this, it is shocking to know that the vaccine efficacy drops off after 6 months. One of my clinical colleagues was telling how an epidemic would naturally die down between 2-5 years. I guess these vaccines are controlling the deaths than infection itself. Dr Thomas, is there anyway, I can get in touch with you to discuss about scientific articles. I sent a request on your LinkedIn. Thank you.
