we are now moving backwards, not forwards. >> next at 5:00, the governor dramatically rolls back reopenings amid an unprecedented covid-19 surge. we will see the impact in alameda and santa clara counties where local business owners feel like they are being pushed to the brink. also ahead, no longer a shot in the dark. another vaccine breakthrough. why this one has an edge over the one announced last week. on that front, community groups in east san jose are mobilizing right now to make sure the vaccine is prioritized for those who need it the most. we'll begin with sobering news. governor newsom says he has to pull the emergency brake on reopening because new cases have just about doubled in the past ten days. >> this is simply the fastest

increase california has seen since the beginning of this pandemic. >> the governor is now putting 94% of the state in the most restrictive purple tier, including alameda, contra costa, santa clara, napa and solano counties. the purple tier means cases are widespread and non-essential indoor businesses like churches, movie theaters and gyms must close and indoor dining must also close. >> meanwhile, san francisco, marin and san mateo are moving back to the red tier. that means cases are substantial and indoor operations are allowed at a reduced capacity. good evening, i'm dan ashley. >> and i'm ama daetz. thanks for joining us. let's get right to liz kreutz with the latest announcement from the state including an apology from the governor. >> yes. there was a lot of news from this briefing. we did get an apology from the governor and also saw every single bay area county but one get moved into a more restrictive tier.

the only one that didn't is sonoma county. with just over a week until thanksgiving, not great news from the governor. covid-19 cases in california have doubled in just the last ten days. on summed the state reported over 10,000 cases for the first time since august. >> this is simply the fastest increase california has seen since the beginning of this pandemic. >> because of that newsom says the state is pulling the emergency brake. today he announced 40 counties are moving back to a more restrictive tier. in the bay area all counties are either in the red or purple, the most restrictive. >> every age group, every demographic, racial, ethnic, in every part of the state we are seeing case rates increase and positivity rates increase as well. >> the state wide 14-day positivity rate is now 4.6%, still much lower than the nationwide average, but a significant increase from a week ago when it was 3.7%.

the rapid rise in cases is illustrated on this map. 41 counties making up 94% of the state's population are now living in the purple tier, with widespread transmission. california health and human services secretary dr. mark ghaly said social gatherings remain a major cause and concern especially before the holidays. >> in red and purple tier counties, we are strongly urging do not gather indoors with other households. this is the type of gathering that is highest risk. >> reporter: at today's briefing, governor newsom also apologies for his recent attendance at a friend's 50th birthday party at a napa county restaurant. a decision that went against his own state guidelines of limiting to three households. >> i made a bad mistake. instead of sitting down, i could have stood up and walked back, got in my car and drove back to my house. instead, i chose to sit there with my wife and a number of

other couples that were outside the household. you can quibble about the guidelines, et cetera, et cetera, but the spirit of what i'm preaching all the time was contradicted, and i've got to own that and so i want to apologize to you. >> now, newsom said he is considering enacting a statewide curfew. nothing announced on that yet, though. he also said the state is changing how it's going to announce county tiers. they're no longer going to wait every two weeks but instead assess it on a weekly basis. he said there could even be more rollbacks this week. >> liz, can you talk a little bit more about how this compares to the country and maybe some other states? >> when you look at the big picture, california is actually doing relatively well. our seven-day positivity rate is 5%. compare that to the nationwide positivity rate which is 9.8%. when you look at specific states that are in even bigger trouble, like south dakota, south dakota has a positivity of 58.4%, so

that does make our 5% seem pretty good. but it is troubling that it is going up and pretty rapidly so, ama. >> absolutely. liz, thank you so much. in the south bay, health officials are seeing some of the highest case counts since the peak of the virus in july and the numbers keep rising. with new restrictions coming as soon as tomorrow, businesses are being forced to adapt even faster than before. chris nguyen has the story from san jose. >> reporter: in santa clara county, a significant rollback that didn't really come as a surprise. the county, which had been expected to move from orange to red on tuesday, as part of the state's reopening framework, will instead jump into the purple tier, meaning more restrictions are on the way. >> we really need every single person living and working in our county to take this extremely seriously. extremely seriously. we know that this virus can spread silently. >> reporter: as county and state officials plead with the public to do their part to stop the spread of covid-19, business

owners are doing what they can to move forward. at alameda, a co-owner is preparing to ramp up virtual coaching and outdoor trainings since fitness facilities won't be allowed to operate inside while the county is in the purpo purple. >> not get too low. >> reporter: revenue is down 30% compared to this time last year. despite the challenge, he still sees this as an opportunity to shine. >> the work that we're putting in now to help others hopefully helps us in the long run. >> reporter: but with covid-19 cases and hospitalizations on the rise, some worry they won't be able to make a comeback. gin nguyen was used to serving a packed dining room. >> i thought i could see the light at the end of the tunnel. >> reporter: now she's laying off her staff, unsure how much longer she'll be able to stay open, especially with the elimination of indoor dining.

>> i probably have to close for good, because we drain out all our saving for the last eight months now. >> reporter: these business owners, though, refusing to go down without a fight. in san jose, chris nguyen, abc 7 news. alameda county is also rolling back its reopening plans now that it is in the purple tier. abc 7 news reporter luz pena spoke with several business owners who saw this coming and are hoping they'll survive these new restrictions. >> reporter: you can call them enlightened or just plain skeptical, but these east bay business owners say they saw this coming. >> when they said 25% sitting capacity, we figured we were going to wait to at least 50% to 75% because we had a feeling this was going to happen to where we were going to shut down again. >> reporter: that feeling was right. in this map we can see the trend that alameda county is experiencing during this recent wave of new infections. today governor newsom announced alameda county is among 28

counties statewide rolling back its reopening plan and skipping over the red tier and moving right into the purple tier, the most restrictive one. >> you don't know what to expect on a weekly basis, on a daily basis. >> reporter: according to the alameda county health officer, the covid-19 case rate has doubled since early october. the all activities and sectors must follow the new guidelines prohibiting indoor dining. >> tables are going to be back in storage and no more chairs or tables inside the restaurant for a while. hopefully not for long, but we'll see. >> reporter: also closing all operations for indoor worship services, gyms and museums. retail shops can remain open at 25% capacity. >> november and december are usually around 30% of your whole year. so to be at really slow capacity or no capacity is really impactful.

>> reporter: but for barbara, her biggest concern are her friends, her neighbors, those who have become family throughout the years. >> i need my neighbors to survive this too. >> reporter: in alameda, luz pena, abc 7 news. governor newsom is reminding everyone that california's vaccine plan prior owe tieses health care workers and communities hit hardest by covid-19. this comes as a second company announced a vaccine showing promising results. >> reporter: a sign of hope today. moderna announcing its vaccine could be up to 94.5% effective in protecting people from covid-19. the company planning to ask for fda authorization in the coming weeks. >> vaccines really are on the horizon. in fact we now have real data in large phase three trials showing that they are safe and effective at preventing covid-19. >> reporter: this comes one week after pfizer said its vaccine is also more than 90% effective.

unlike pfizer, moderna's vaccine can be stored at regular refrigeration temperatures, which could make distribution easier. >> in public health we do not get 90% plus effective vaccines often and here we have two vaccines with that type of efficacy. >> reporter: hhs secretary azar tells abc news vaccines could be contributed to 20 million people by the end of the year with the most vulnerable populations getting them first. experts say widespread vaccination could take months. as we just mentioned, the most vulnerable populations will be vaccinated first. advocates in a san jose neighborhood with high infection rates are working on a priority plan for residents there. community leaders told david louie why they're raising their voices now. >> reporter: east san jose neighborhoods rank among the highest in the county for covid-19 cases. community groups represent its many latino and vietnamese residents hope that will be

factored in in planning for distribution of vaccines. >> we want to have a seat at the table just so that whatever plan that they're putting out reflects the culture and background of our resident. >> reporter: luna or latinos united for a new america is one of seven community groups meeting weekly to form recommendations to community leaders. many in east san jose live in cramped housing or extended family households so the group see access to vaccines and educating the public about their safety as an important mission. >> they know that we have their best interests in mind. who better than this organization to, you know, talk to people about whether they should trust the vaccine or not. >> reporter: county health officials indicate here's who will set priorities for access to vaccines. at the federal level the cdc has an advisory committee. california has a working group that will set state guidelines. santa clara county says it will work with local community

partners. local groups say they had to lobby to get covid test sites in east san jose early in the pandemic. they don't want the same thing to happen for access to vaccines given the high infection rate. >> the testing sites didn't go to those communities right away, and so i think that we learned from the mistake. we learn fred what we didn't do right and we tried not to do it again. >> reporter: east san jose groups hope to have their plan ready for leaders in three or four weeks. david louie, abc 7 news. still ahead, the pressure to close a san jose airport heats up. why some say the planes that fly there are a danger. and the wonder of wet weather. sandhya patel will be here with that. also ahead if you can't beat 'em, twitter goes after
