it is a new study from the hoyos institute for immunology, saying that the memory helper t cells thatecognize the common cold will also be getting a head start in fighting off covid-19. researchers have also said that this may explain why some people show milder symptoms of the virus while others get very sick. researchers say they need more information. >>> the nation's first contract tracing app using technology for apple and google is being ruled out now. virginia is the first state to use this app, it is called covid-19 wives, they share signals to track people in close contact. the app that allows people who catch the virus to notify others a, and do it anonymously. other states are also considering adopting the application. >>> we are following developing story about a shooting, involving san leandro police officers in oakland. what the officers have said so far, about what had let up to the shooting. >>> more calls in vallejo for police reform, the police chief now supports firing one of the officers that were involved in the shooting death of willie mccoy. >>> pro golfs first

he's a professor at the center for infectious disease and vaccine research at the la jolla institute for immunologyi asked for his read on the time fame for the vaccine. >> any way you look at it there's been a lot of actually really good vaccine news just in the past two weeks. actually, it's been kind of a tidal wave of data. and what looks good is that there are multiple vaccine candidates that have passed all the tests they've been asked to test so far. so really safety tests and that they generate an immune response in people and that they have activity in monkeys. those are all really good things. feel, one of the things that we did in la jolla was try to answer the question of how much immunity does a person need to have. because that's one of the things that affects -- how good is a vaccine going to have to be to stop covid-19, right? so one way to do that is to ask, well, what's an immune response look like in an average person who caught covid-19? because usually what you'd like is for a vaccine to generate an immune response that's at least as good as what you'd see in an infected person
