let’s bring an emergency physician and abc news medical contributor dr darian sutton dr sutton good morning let’s start with this new development out of the uk they’ve announced an update to their vaccine guidelines allowing vaccines to be mixed and matched in cases where a second dose might not be available or if the manufacturer of the first shot isn’t known this contradicts cdc guidelines here in the states though so what’s your take on this good morning diane while i understand why this is being done in an effort to vaccinate as many people as possible this is really uh venturing into uncharted scientific territory so i would advise against it because it’s based off of information we simply do not have and then the uk is also delaying second doses of the vaccine to instead give as many people as possible a single dose first now a california doctor suggesting the u.s consider doing the same but health and human services secretary alex azar said on gma this morning that the u.s would follow the data and do two doses so what do you make of that what does the data tell us here so right now the data is very limited right now pfizer has a statement that states that they do not know what information happens information or efficacy after the first dose and we have some little information from moderna about the possible efficacy that is available after the first dose but it is nowhere near the efficacy that was reported around 95 percent after both doses for both pfizer and moderna i think right now doing a single dose shot is not only at risk of leaving people partially vaccinated with the false sense of security but it also can undermine the public trust and and complicate uh the uh the availability excuse me the understanding of how this vaccine works and we’ve been working so hard to get everyone to understand the simple benefit of getting both doses so it would make it a lot harder and now that the holidays are over the fear is that mid-january could bring what dr fauci called a surge upon a surge and a really dark time now is there anything that can be done to prevent this at this point do we need more restrictions here like we’re seeing in the uk for example well i don’t think that blanket restrictions are something that is effective i do think that targeted restrictions are important for example here in los angeles our rates are our surges are are complicating and maximizing the capacity available in hospitals making everything difficult so i do think that when rates become high enough and hospital capacity becomes high enough that restrictions need to be put in place to help tamper that but across the united states every state is a little bit different i think also that we need to augment testing right now according to cobit tracking project the highest amount of testing that we’ve seen on a daily basis is around 2 million and some scientists and analysts suspect that we need approximately 9 million tests available to americans in order to help people understand their diagnosis or the possibility of them having covid19 and we also need that testing to be efficient so that they get the results quickly a lot of these variables are need to be put in place to help decrease the amount of people coming into the hospital all right dr darian sutton always great to get your take thank you hi everyone george stephanopoulos here thanks for checking out the abc news youtube channel if you’d like to get more videos show highlights and watch live event coverage click on the right over here to subscribe to our channel and don’t forget to download the abc news app for breaking news alerts thanks for watching
