Vaccines have raised expectations of the Governments and people that they will be efficacious for bringing an end to COVID-19 pandemic. However, COVID-19 is a special pandemic that may most likely prove to be an exception. No vaccine can be 100% efficacious. Currently released vaccines for COVID-19 are claimed to be 70 â?? 94% efficacious. This level of efficacy was enough for controlling epidemics of several diseases in the past. However, this may not be enough this time because this novel coronavirus - SARS-CoV-2 is different than earlier pathogens encountered by human race. The novel coronavirus has very high transmissibility, very fast multiplication rate, very high mutation frequency and add to that the now coming up of recombinants of mutants of novel coronavirus that combine above adverse characteristics with ability to weaken efficacy of vaccines. Add to it impossibility to cover the entire population within reasonable period by vaccination and considerably high number of people non-compliant with precautions to avoid infection and spread of the virus. Longer the pandemic is allowed to linger, higher is the probability of emergence of more dangerous mutations and recombinants of mutants including the ones which shall not be vulnerable to current vaccines. It is being acknowledged that only vaccine-centric approach in case of COVID-19 is not likely to be adequate. This brings in focus the indispensability of NK Cell Activity improvement in vulnerable section of the population by oral consumption of Natural Killer Cell Acitvity Booster prior to and/or concurrent with vaccination for achieving better probability of control/end of COVID-19 pandemic. Vaccination drives have already started in India and in other countries. Immediate induction of NK Cell Activity Boosters is needed before they reach such an advanced stage that the early vaccinated ones would have already lost the opportunity of at least concurrent consumption of NK Cell Activity Booster. A practically viable NK Cell Activity Booster is described.
