The increased number of cases theyre seeing is this new variant. think of all the variants that have emerged and the vaccine still demonstrated efficacy. theres no reason to believe were going to lose them against this. one >> doctor, do you agree with the central point hes making their? >> yes, which is that we still dont know a lot about the epidemiology. a lot of it is observation and gathering that data. it is seeing what omicron does in other settings. one other example i give is that there...

Matter where you are in that cycle of fully vaccinated with the traditional two shots and the boosters? the administration is saying booster wills be the key here, but if a fully vaccinated person has a mild case and theyre threw it, what does that tell us about the efficacy of the boosters and the three-shot regimen? >> to answer the first part of that question, first it matters where you are in that regime of getting those tests, getting those vaccinations. being fully vaccinated, possibly get...

Here when dangers can we find out about omicron now that we had a chance to bring it to their lab. >> now that we have access to the sample were able to culture the virus. this answers critical questions about omicron. what is the transmissibilty, and does it impact the potential effectiveness of vaccines. >> as you mentioned a moment ago there is now a second identified case in minnesota. the good news, if there is any, is that as they pop up in our sequence in these various labs, it gives them...

A bit more about the laboratory results that tell us about the effectiveness of these vaccines. i think to most people, it might feel that based on this mutations you may see some decrease in infections. what youre likely but -- a decrease in protection from infections. that will probably be linked to how many doses of vaccines youve had. so if youve had three doses, your booster, your most likely will be protected. having said that, everybody, most people agree there might still be very protect...

Severely ill. i hope it remains that way, that ideally omicron does not cause very severe illness. it is far too soon for us to say. there are some preliminary reports that most of the individuals who are getting infected with omicron are those who are unvaccinated. and so i do hope that well find with time that vaccination and in particular getting that booster dose will give a level of protection against omicron, so this is the message that were sending to all of our patients here in the u.s.,...

I wonder if the distinction here is reduced protection against infection. is that the difference here? >> i dont think that any of us know for certain at this point. what we hope that the vaccines will do ultimately is, first, to reduce severe illness, severe enough to cause hospitalization and death, but ideally you also want to get vaccinated to stop from being sick in the first place. who wants to get ill? who wants to transmit to others? we dont know which it is at this point. ideally it is ...

The last couple of days that the cases are going up that we may be looking at more transmissible variant. however, until we see those variants sort of do the same thing in other communities, you know, other settings, other vaccination rates in other countries, we wont know about the true transmisibility. over the next few weeks i think what we are going to learn, you will learn a bit more about the laboratory results that tell us a bit more about the effectiveness of these vaccines and i think m...

Who are fully vaccinated and who have had a booster shot are protected against omicron but didnt provide any details about that claim. health officials in the u.s. say it will take weeks to find out just how well the existing vaccines protect against this new strain. the ceo of moderna says he doubts the effectiveness of his vaccine is at the same level as it is with the delta variant, both moderna and pfizer say theyre working on a vaccine specific to omicron just in case its needed. >> i doubt...
