we ask experts your questions everyday at 3:00 to get answers in real time. today, the cdc decided to extend the soon to expire mask mandate on transit for another two weeks. the biden administration extended the public health emergency for another three months. ucsf's dr. bob -- will join us to answer your questions. also, if you shop on at sea, you may have noticed some online shops are closed. some sellers are on strike to protest the platform's new fees. we talked to an npr reporter to explain why this is important

yacht at sea. giants assistant coach, becoming the first woman to coach on the field to coach during an action -- during a game. it happened against the padres. sports director larry beil joins us to talk about nakken, the giants come of the warriors, staffed curry, all of it. larry: what about dr. --? karina: i'm sure we'll have questions. larry: i'm a huge fan. karina: we are also fans of alyssa nakken, she did first base last night. never happened before with a woman. larry: correct. the circumstances here were kind of unusual in that and one richardson, the normal first base code for the giants, ended up getting in a beef with one of the padres verbally. they started tripping and antoine got thrown out.

the giants needed somebody to coach first base. in the giants dugout, there is a long series of steps that go down and lead to a batting cage. here you see antoine getting tossed. that got resolved today. anyway, down the steps there is a batting cage. alyssa's job was to help players get ready for their next at-bat. suddenly the word comes, we need you to coach first base. she did not have her uniform on. she had to run and get her uniform. you can see the giants for the first time were wearing their city connect unis. interesting story about the helmet that i will get into in a minute. she gets her jersey, she goes out there, then realizes it is really cold. and then she is like, i wish i had more time. i would have put on more layers.

right there, just what i am going to get to. -- immediately recognizing history in the making. r. w that this wa larry: may be way back whenaee'e somewhere in some league. karina: what is her history? she played softball? larry: sacramento state. she was a really talented softball player. she was never trying to become a coach for the giants. she was working in the giants front office. she was handling things like special events where they would

have liked, race, any kind of thing that involved the ballpark. she was doing outside activity. she was not coaching baseball. in 2020, she made such a strong impression on everybody in the giants front office. i talked with a friend of mine and they could not read -- rave more about alyssa nakken. they loved her so much. that is where gabe kapler stepped in as he was becoming manager of the giants. gabe has totally overhauled the staff and gotten younger and more innovative. he was the one who was like, hey, i am hearing a lot of good things about alyssa nakken. maybe we ought to try this out. karina: it sounds like everybody thinks they have incredible empathy and commit again skills. that came across in an interview she did with karina nova last

month for women's history month. >> it is silly that for so long they have only pulled from 50% of the candidate pool. you have so much more opportunity to actually select the best person for that role. i think just naturally come of the teams are going to see just how much of a competitive advantage you can have by adding diversity to your staff and to your clubhouse. kristen: so true. now the question is, beyond her singular achievement, will this open doors to more women? or do you think this will lead to a more regular appearance? larry: if antoine keeps getting thrown out. just joking. one of the things i was told today is that alyssa has been active in trying to recruit other women to show them, especially from her old team, you may want to think about the

viability of a career in baseball that you probably didn't have any notion was even available to you a few years ago. she is groundbreaking in so many ways. she may be the lead recruiter for major league baseball in terms of getting more women involved in the sport. the helmet story i wanted to tell, this is the city connect helmet. this is the first game they used those helmets. that's not even her helmet, i don't think. kristen: it fits. larry: she grabbed whatever she could grab. after the game, everybody realizes history has just been made. some part of her uniform is going to cooperstown hall of fame. larry: the helmet is going to cooperstown. they asked her permission after the game. is it ok if we send the helmet? she said, you know, i only just grabbed it once. i barely had it on. there were like, it is history.

gabe has been so great with this. he has been quoted as saying he thinks so highly of alyssa that someday she could be a manager herself. kristen: wow. larry: we are starting to see this and other sports like the nba. i think we are not too far away from having becky hammon with the spurs possibly getting a job as the head coach of a team. baseball has been kind of prehistoric in this area. essentially you've got a bunch of grumpy old men that want to do it like we did back in the 1970's. at first base smoking a cigarette. to have this transformation where not only is she great at her job by all accounts, some of the giants players have noted. before the game, they will throw a football around, they like to do that as a warm-up. kristen: stay loose, have fun. larry: she will throw the

football with and they are like, alyssa nakken has an arm. she is a real athlete i think they respect her so much, whereas initially a lot of teams would say, who is this girl? kristen: believe me, i -- not me as a player, but as a mom, when a girl first joined their all-star team, the boys were like, you are going to be in our dugout? really? until she hits her first home run and then. larry: we love you, high-fives. kristen: fantastic. larry: alyssa has made that kind of impact on the team and they do not look at her as the giants female coach. she is just a coach. she is an empathetic -- i am going to tell this story anyway

even though the person that asked me not to say too much about it. a friend of mine in the giants organization was having a tough time personally because of the loss in the family. alyssa nakken came over and said, come on, let's just talk for a while. took time out of her day, 30 minutes, to make sure this person was ok mentally. that is not her job, but it just shows the empathy she has come of the type of person she is and why the giants embrace and accept her so readily because she is just a great person. kristen: history could not have happened to a nicer person. we got ago, but 30 seconds, playoffs for the warriors start saturday here on abc number seven -- larry: tomorrow is a big day. the warriors will hold a scrimmage, it will be the first time he is with a team on the

court playing since the century with marcus diving into the back of his leg about a month ago. if he comes out of the scrimmage ok, they're going to check him friday to see if there is swelling, discomfort, pain. if he is fine, he is playing saturday. kristen: sounds good, we will talk more about this at 4:00. larry: tell the doctor i said hello. kristen: will do. up next, we have the latest

kristen: big news today, the biden administration extended the national covid public health emergency for another three months. also, the cdc extended the mask

mandate for air travel and public transit for two weeks. it would have expired in five days otherwise, but now it will be in place at least through may 3. here to discuss boosters, variance and more, chair of the department of medicine bob walking her -- >> great to be here. kristen: the cdc extending the mask mandate for trains, planes and buses. is this what you expected? >> yeah. i had a feeling they would. it is a little too uncertain. cases are taking up in certain parts of the country, the bay area as well. not very much. it is not what you would call a surge. but, it is worrisome enough that they want to give it a little more time and see what plays out. my guess is we will not see a surge and they will probably take away the mandate in a couple of weeks. we will have to wait and see. kristen: if you were the

decision-maker, would you personally remove the mask mandate after two more weeks? when you weigh things like the airline saying we can't really enforce this, flight attendants unions saying we have immunocompromised members, they're still not vaccines for kids under five. what do you think? >> i think you have covered all of the bases. i just tweeted about this, i would say the arguments to maintain the mandate have become weak enough that if cases are not going up may 3, they should probably get rid of the mandate. i will continue to wear a mask. if the mandate goes away, i will wear the mask even more religiously. the things we know are there are few outbreaks. no super-spreader's on airplanes

if you wear an n95 or equivalent, you can say safe. everybody has had the opportunity to get boosted. everybody can get antivirals if they get infected. when you weigh that, i will wear a mask. but, that is not question when you think about a mandate. is the government's interest in making people do stuff they may or may not want to do? is it strong enough to merit a mandate? i would say now it probably isn't. kristen: still no vaccine for children under five. pfizer and maternal are both in the running. we thought there would have something by february, then march, what is the timeline now? dr. wachter: you know what i know. people have talked about coming out with results in the next month or so. we just have to wait and see. early results from the vaccine trials were disappointing. part of the challenge with the

little kids is you have to guess the dose. you do not want to give too high a dose, because then all of the kids have high fevers which is unpleasant. you don't want to give too low a dose, because they won't have a response they need. on the first try, they gave too low a dose. they have to go back and give a higher dose. my guess is we will find something that works and it will come out in the next month or two. kristen: do you think parents will even want it when approved? given the pandemic is over mentality, do you worry there won't be enough takers? dr. wachter: yes. we have seen that in 5-11-year-old kids. if i had a kid that age, i would make sure my kid was vaccinated. in part because even though the risk that a young child is going to get very sick and die is very very low. it is not zero. the more we learn about long

covid, the more concerning it is. not just some people having symptoms for months later, but there have been studies that have shown a year later, increased risk of heart attacks, strokes, blood clots, diabetes. that was from delta and other viruses, not from omicron, not in vaccinated people. when you weigh all that and the vaccines are safe, if i had a very young kid, once the fda says it is good, i would get my kid vaccinated. kristen: you alluded to the fact that cases are up. philadelphia has brought back its mask mandate. but, numbers remain low for deaths and hospitalizations. overall, are you concerned where we are at now? dr. wachter: somewhere in between. cases are still relatively low, though they have gone up in the last few weeks. they have gone up to levels that are still fairly low. people say, what about the home tests?

true, we are missing cases. when you look at test positivity rates and virus in wastewater, by all measures there has been an uptick. we expected an uptick because people are being less careful, traveling more, not wearing masks. the idea that there is an uptick is expected. we are not seeing a significant rise in hospitalizations and death. i think we have to watch carefully because there are new variance around. see what happens. at least so far, i am not terribly worried but it bears watching. kristen: you always explain your pandemic personal choices really well on twitter. that is probably why you have so many followers. what choices are you making now with today's still fairly no -- fairly low numbers? what kind of choices are you making? dr. wachter: i got my second booster a week ago. it was no big deal.

i made a choice to change brands. i got moderna after three pfizer's. there is a little bit of evidence it may be better than sticking with one. not a -- not a lot, but enough to make me do that. i am doing indoor dining in san francisco which has a low case prevalence rate. when i go into other spaces with people whose vaccine status i do not know, i am wearing a mask. if it feels non-covid, meaning not too many people, i will generally wear cloth that a surgical on top of it. if it feels risky, i will wear a n95. when flying, eyewear an and party much the whole time, i take it off or 30 seconds to wolf down some food. if they end the mandate, i will keep it on. kristen: thank you for sharing. generally whatever you say you

will do is what i choose to do. dr. wachter: i am so much older than you. but yes, i understand. [laughter]kristen: always great talking with you dr. bob wachter . next time we've got to get you want to talk baseball. dr. wachter: that will be fun. kristen: take care. coming up, etsy sellers on

5.3 million active sellers sandhya: -- sellers. these sellers are local artisans that create anything from custom wedding dresses to stickers to stamps. all kinds of things. they are independent artisans and they have their shops on etsy. etsy is the website that they do all of their business. customers come and purchase from them there. and that is where they do business. kristen: they did a lot of mask sales in the last two years. it made etsy a lot of money because they take a commission. explain what etsy did that anger so many? >> starting this week, the company said they were going to increase the transaction fees from 5% to 6.5%. sellers were really unhappy with that because that is -- the

amount that comes directly out of the sale that each seller makes. kristen: i know it is hard to say because some of them are part-time and some of them are full-time, some have large businesses, but how much is that? how much does that translate to for your average seller? is that a big deal? >> to them, they feel like it is a big deal. in addition to other costs they have to deal with. they have to buy their own supplies, shipping, handling. the company has additional fees for these sellers that is taken out of the final sale in a lot of cases. for them, it is too much. kristen: etsy did make a statement we want to share with you. they say these funds are necessary for making improvements like marketing. "our seller success is top priority. we are receptive to seller feedback and the new fee structure will enable us to increase our investments in areas outlined in the petition."

there was a petition, i addressed their marketing and customer support. with this petition, what do sellers hope to achieve? in this protest? >> really hope that etsy listens to their concerns that may the company will go back on their transaction fee increase, that they will address other problems on the prop -- problems on the platform that sellers complain about which includes resellers on the site, which some people say are masking -- products that often also steal from other artists designs. they feel etsy is not doing enough about that. they also want the option to opt out of these off-site advertisements, listings created by etsy but posted on the internet for customers searching for certain things, but the artist has no power to control that, no option to opt out.

that could take a good chunk out of their final sale. they are hoping word gets out about etsy's practices they view as unfair and that etsy listens to them and make changes on the road. kristen: these sellers are not employees. they are just using the platform. they do not have a union. do labor laws even offer them protection of some sort? or even enable such protest? >> they do not. they do not have a union. they do not have an employer-employee relationship. they are not covered by the national labor relations act. that does not change the fact they can organize in this way. it is a collective labor action, just not a union action. kristen: 30 seconds, i wonder if this impacts shoppers. do shoppers care? we know it is a pretty small

fraction that participated. does it impact shoppers? >> some customers have seen the petition, have seen the media reports on this and sided with them. some buyers have said they will also go on a strike in solidarity. kristen: jaclyn diaz, npr reporter. let's chat over

kristen: think you so much for joining us on this interactive show, getting answers. we talked about giant's alyssa nakken making history, the extension of the mask mandate on airplanes and public transit advice some etsy sellers are on
