friday is starting earlier than ever this year . this is nbc "nightly news" with lester holt. good evening, everyone further acknowledging covid vaccines while incredibly effective lose some of their punch over time, an fda safety panel has just given its endorsement to booster shots for many americans who were fully vaccinated with a two-dose moderna vaccine. it is not the final word but the panel's recommendation for a third moderna shot mirrors what the cdc recently decided for pfizer boosters, recommending them for older people and those at higher risk of covid infection nearly 188 million americans are now considered fully vaccinated with close to 9 million having already received boosters yet, there remain questions on whether the extra shots are really necessary for most people miguel almaguer has late details. >> reporter: moving a major step toward authorization, tonight an fda advisory panel says some americans fully vaccinated with moderna should get its booster. the unanimous recommendation not yet green lit by the cdc applies to those 65 and older and others at higher risk of severe disease because of health conditions or exposure at their job. >> i think we all expected a third shot was going to be prescribed for those at high risk the question here is did the science appear to justify such a decision >> reporter: providing documents full of data, moderna argued the fda should authorize its booster for recipients at least six months after their second dose, citing break-through infections and waning immunity over time. but the fda notes even without a booster, vaccines still afford protection against severe covid-19 disease and death in the united states. >> there has been some push back against moderna because its efficacy against hospitalization remains high, so why the need for a booster? >> the vaccines are still working for a vast majority of americans. it is keeping people out of the hospital it is keeping people from being infected they're not in urgent need of a booster. >> reporter: with nearly 70 million americans already fully vaccinated with moderna, those who qualify join the same group of pfizer recipients who can also get a booster with moderna's original doses larger than pfizer's its third shot will be a half dose authorities saying today the data are not perfect, but these are extraordinary times. today the president again making the sell for boosters. >> these boosters are free say it again they're free available and convenient to get. >> reporter: as johnson & johnson's case for a booster comes up tomorrow, tonight for millions, vaccinated with moderna, the extra dose of protection may soon be a shot away >> and, miguel, this is obviously a big decision today, but not the last on authorizing a moderna booster. what happens now >> reporter: well, lester, now the fda advisory panel that has agreed the fda itself still needs to sign off. then a cdc advisory committee needs to make a recommendation next week before the cdc director gives the okay a few more hoops before we get the green light on a moderna booster. >> thank you very much. tonight more than 10,000 workers are
