But as we tried these extraordinary things, as people went to this trouble to try and rework their tactics, we went back to the vaccine -- it's a 50-year-old vaccine -- and we thought, surely we can make a better vaccine, so that when they finally get to these kids, we can have a better bang for our buck.
Dar pe masura ce incercam aceste lucruri extraordinare, in timp ce oamenii treceau prin aceste greutati pentru a incerca sa refaca tacticile, ne-am intors asupra vaccinului-- un vaccin vechi de 50 de ani-- si ne-am gandit, sigur putem sa facem un vaccin mai bun, ca atunci cand ajungem intr-un final la acesti copii, putem sa avem mai multe rezultate pentru banii investiti.
