to offer or actually suggest that people get a fourth shot there if you re over 60 years old. what do you think about that? well, the moment i saw the results of the third booster shot from the pfizer vaccine failed to protect most people after three months, i immediately sent notes to all of my friends who most of whom are over 60, as you might imagine, to get the fourth booster. in fact, i have my fourth booster, as does my wife. it s a very sound policy. it s the only thing i think we can do from the vaccine front right now until we either have better vaccines or better drugs. i will say that s not nothing though. you say it wanes after three months. but three months is three months. yeah. it is. . it counts. if you re i m in the middle of i got boosted three weeks ago, and i feel great about the fact that i got boosted three weeks ago. and i feel i have at least some protection over this omicron
poses a different threat. on the vaccine front, moderna says it will seek authorization for its omicron-specific vaccine this summer, plus a team in texas thinks they have come up with yet another vaccine that could be a game changer not just in the u.s. but for the rest of the world. morgan chesky has that story now. reporter: at texas children s hospital in houston, there is much more than meets the eye because past the exam rooms inside this lab lie what is they believe to be the potential silver bull let for taking down covid-19. our lab is the united nations of science. reporter: a team of doctors led by dr. peter hotez and dr. elina mattazzi dedicating their careers to fill a vaccination gap. delta rose out of an unvaccinated population in india the beginning of last year, then omicron rose out of an unvaccinated population out of southern africa. mother nature is telling us what s going to happen. as long as we refuse to
