BE ADMINISTERED, PEOPLE IN THE COMMUNITY ARE SENDING IN QUESTIONS TO OUR NEWSROOM. KCRA 3’S BRITTANY JOHNSON IS TRACKING THEM. SHE SPOKE WITH AN INFECTIOUS DISEASE DOCTOR TO GET YOU ANSWERS. BRITTANY: AS ADDITIONAL PEOPLE BECOME ELIGIBLE TO RECEIVE THE VACCINE, WE RECEIVED MORE QUESTIONS. FIRST QUESTION -- CAN YOU TEST POSITIVE FOR COVID-19 IF YOU HAVE ALREADY RECEIVED A CORONAVIRUS VACCINE? >> THE ANSWER TO THAT IS PROBABLY YES BUT NOT 100% CERTAINTY. WE KNOW THE VACCINE PREVENTS DISEASE FROM OCCURRING IN 95% OF PEOPLE, WHICH MEANS 5% COULD ACTUALLY STILL GET DISEASE. WHAT WE DON’T KNOW IS IF THE VACCINE ACTUALLY ONLY PREVENTS INFECTION OR IF IT JUST PREVENTS DISEASE. BRITTANY: IF A PERSON HAD COVID-19 AND RECOVERED, ARE THEY IMMUNE TO INFECTION? >> THE DATA SUGGESTS PEOPLE MAY BE IMMUNE OUT TO EIGHT MONTHS. WILL THAT WAY IN OVERTIME -- WILL THAT WANE OVER TIME? MOST LIKELY. WILL THAT BE LESS EFFECTIVE AS THE VIUS CHANGES? MOST LIKELY. BRITTANY: WE ARE THINKING THIS COULD BE SOMETHING LIKE A FLU SHOT, SOMETHING YOU HAVE TO GET YEARLY? >> I’M THINKING IT WILL BE SOMETHING LIKE THAT. MAYBE EVERY TWO OR THREE YEARS, BUT I THINK IS THE VIRUS CHANGES, THE VACCINE IS GOING TO HAVE TO CHANGE. BRITTANY: HOW CAN WE REACH HEARD IMMUNITY IF WE DO NOT KNOW HOW LONG VACCINES WILL BE EFFECTIVE FOR? >> THE WAY TO STOP THIS IS FOR THE ONE PERSON WHO IS INFECTED BUMP INTO ALMOST NOBODY WHO COULD BE INFECTED BECAUSE THEY ARE ALREADY IMMUNE AND THEY HAVE BEEN VACCINATED. THEN THE NUMBER OF CASES START DROPPING. EVEN IF THE IMMUNITY WANES OVER TIME, THAT’S WHY WE MAY HAVE TO RE-VACCINATE PEOPLE. BRITTANY: IS THE VACCINE RECOMMENDED FOR WOMEN WHO ARE PREGNANT OR WOMEN PLANNING TO CONCEIVE? >> I WOULD SAY THAT UNTIL WE HAVE VACCINATED A NUMBER OF PREGNANT WOMEN, WE WILL NOT KNOW FOR ABSOLUTE CERTAINTY THAT IT IS SAFE, BUT WE KNOW FROM VACCINATING WOMEN WITH OTHER LONG-STANDING VACCINES THAT AS LONG AS THE VACCINE DOES NOT CONTAIN A LIVE ORGANISM, IF IT IS A BACTERIA OR VIRUS, IT IS SA
