This was not the first synthetic virus -- a polio virus had been made a year before -- but it was only one ten-thousandth as active and it took three years to do.
Acesta nu a fost primul virus sintetic -- un virus al poliomielitei a fost făcut cu un an înainte -- dar era de zece mii de ori mai puțin activ şi ne-a luat trei ani să-l facem.
