Johnson & Johnson Covid-19 booster shots show big increase in immune response

NEWS THIS MORNING AS THE NATION TRIES TO FIGHT THE DELTA-FUELED COVID SURGE. JOHNSON & JOHNSON SAYS THAT ITS PRELIMINARY DATA SHOWED THAT PEOPLE WHO RECEIVED BOOSTER DOSES OF ITS ONE-SHOT COVID-19 VACCINE HAD A BIG SPIKE IN ANTIBODIES. CNN’S SENIOR MEDICAL CORRESPONDENT ELIZABETH COHEN HAS BEEN LOOKING AT THE DATA HERE. THIS IS IMPORTANT BECAUSE IT SHOWS THAT NOT ONLY ONE VACCINE, IF YOU GET THAT BOOSTER, YOU CAN REALLY BOOST YOUR IMMUNITY TO THIS. >> THAT’S RIGHT. LET’S GO OVER A LITTLE BIT WHAT THE JOHNSON & JOHNSON VACCINE IS. IT’S BEEN A WHILE SINCE WE’VE SPOKEN ABOUT IT. SO, JOHNSON & JOHNSON HAS BEEN CALLED THE ONE-SHOT WONDER. YOU ONLY NEED ONE SHOT. BUT REMEMBER, IN THEIR CLINICAL TRIALS IT WAS 66% EFFECTIVE AGAINST MODERATE AND SEVERE COVID. GOOD, BUT NOT AS GOOD AS THE OTHER TWO VACCINES THAT AT THAT TIME WERE MORE AROUND 95%. SO LET’S TAKE A LOOK AT WHAT THE STUDY DID. IT WAS A SMALL STUDY. WHAT THEY DID WAS GIVE EVERYONE ONE SHOT. WAITED SIX MONTHS LATER, AND ANTIBODIES INCREASED NINE FOLD. IN OTHER WORDS, FROM THE ONE SHOT, ABOUT 28 DAYS LATER, ANTIBODIES REACHED A CERTAIN LEVEL. BUT WHEN THEY WAITED 28 DAYS AFTER THE SECOND SHOT, ANTIBODIES INCREASED NINE TIMES WHERE THEY WERE SHORTLY AFTER THAT FIRST SHOT. THAT REALLY IS SAYING SOMETHING. NOW, JIM, I’LL ADHERE THAT ONE-SHOT WONDER, SEVERAL PUBLIC HEALTH EXPERTS WE TALKED TO SAID IT DIDN’T QUITE WORK OUT THAT WAY. ONLY 14 MILLION AMERICANS HAVE RECEIVED JOHNSON & JOHNSON. COMPARE THAT SAY, TO PFIZER WHICH IS 100 MILLION JOHNSON & JOHNSON VACCINE TO BE USED AROUND THE WORLD. ONE SHOT DOESN’T NEED TO BE KEPT AT THESE REALLY COLD TEMPERATURES. IT HASN’T QUITE WORKED OUT THIS WAY. WE’LL SEE IF THIS CHANGES ANYTHING. >> FOR SURE. OPTIONS ARE GOOD. JUST HAVE TO GET PEOPLE VACCINATED. >>> LET’S TALK ABOUT CHILDREN. CASES IN CHILDREN, CAN’T BE VACCINATED UNLESS THEY’RE 12 AND ABOVE, OUR NOW REACHING LEVELS WE HAVEN’T SEEN IN MONTHS. WHERE IS THAT AND WHERE IS IT EXPECTED TO GO? WE’RE NOT EVEN INTO WINTERTIME. MOST KIDS AREN’T BACK IN SCHOOL YET. >> THAT’S RIGHT. SO THESE NUMBERS ARE REALLY QUITE ALARMING. LET’S TAKE A LOOK AT WHAT HAS HAPPENED, EVEN JUST OVER THE COURSE OF THE SUMMER. IF YOU TAKE A LOOK AT THE WEEK OF AUGUST 12, THERE WERE ABOUT 180,000 NEW CASES AMONG CHILDREN. COMPARE THAT TO THE WEEK OF JULY 15th. NOT EVEN A MONTH BEFORE. ONLY 38,000 NEW CASES IN THAT WEEK. THAT REALLY TELLS YOU SOMETHING. NOW, SOME PEOPLE MIGHT LOOK AT THESE NUMBERS AND SAY, OH, DOES IT REALLY MATTER? CHILDREN, YOU KNOW, A TINY PERCENTAGE END UP IN THE HOSPITAL OR END UP DYING. THAT IS TRUE. BUT THE MORE CASES YOU HAVE, THE MORE HOSPITALIZED CHILDREN YOU’RE GOING TO HAVE. THE MORE DEAD CHILDREN YOU’RE GOING TO HAVE. AND AS DR. ROCHELLE WALENSKY THE HEAD OF THE CDC PUT IT TO A MEMBER OF CONGRESS, CHILDREN ARE NOT SUPPOSED TO DIE. YOU SHOULDN’T EVEN HAVE ONE CHILD DEAD FROM THIS VIRUS. SO IT IS WORTH TRYING TO GET THESE NUMBERS DOWN. >> ELIZABETH COHEN, THANKS VERY MUCH. LET’S SPEAK MORE WITH DR. CARLOS DEL RIO, EXECUTIVE ASSOCIATE DEAN OF EMORYIE SCHOOL OF MEDICINE GRADY HEALTH SYSTEM. DR. DEL RIO, ALWAYS GOOD TO HAVE YOU ON. HELP US UNDERSTAND WHAT WE’RE LEARNING HERE ABOUT CHILDREN. LISTEN, I’VE GOT TWO KIDS BELOW THE AGE OF 12, NOT VACCINATED. I DON’T WANT THEM TO GET INFECTED CERTAINLY, BUT I DO LOOK AT THE DATA AND I KNOW IT’S A VERY SMALL PERCENTAGE OF CHILDREN WHO GET SEVERE DISEASE. HOW SHOULD PARENTS VIEW THIS? SHOULD THEY VIEW THIS AS A MOMENT TO TAKE REASONABLE PRECAUTIONS, WEAR A MASK IN SCHOOL, FOR INSTANCE, WATCH FOR NEWS OF APPROVAL FOR A VACCINE FOR 12 AND UNDER? OR DO THEY NEED TO LOOK AT THIS, IN YOUR VIEW, MORE — WITH MORE CONCERN? >> JIM, I WOULD THINK ABOUT IT THE WAY YOU WOULD THINK, FOR EXAMPLE, ABOUT LETTING YOUR KIDS WALK TO SCHOOL OR, YOU KNOW, DRIVE THEIR BIKE TO SKOOM. YOU WANT TO ALLOW THEM TO DO THAT, BUT YOU WANT TO DO IT IN THE SAFEST POSSIBLE WAY. YOU WANT TO PUT A HELMET ON THEM, WHEN TO CROSS THE STREET, ET CETERA. I WOULD SAY THE SAME WAY. THE BEST WAY TO PROTECT CHILDREN NOT CANDIDATES TO BE VACCINATED, 12 AND UNDER, ARE TO DO TWO THINGS. ONE, HAVE ALL THE ADULTS AROUND THEM VACCINATED. ANYONE OVER THE AGE OF 16 SHOULD BE VACCINATED. AND NUMBER TWO, WE NEED TO MAKE SURE EVERYBODY WHO IS WITH THEM AND THOSE KIDS ARE ALSO WEARING A MASK. AND THAT’S WHY, YOU KNOW, BAFFLES ME THAT WE HAVE HAD SO MANY CONTROVERSY ABOUT MASKING IN SCHOOL. IF I WAS SENDING MY KIDS THAT AGE TO SCHOOL, I WOULD WANT THEM MASK AND ALSO ASK THE TEACHER, ANYBODY WHO IS WITH THEM ALSO MASK. REDUCE THE RISK TO THE KIDS IS CRITICALLY IMPORTANT. >> I’M WITH YOU. THE IDEA THAT PEOPLE EITHER FOR POLITICS OR NOT UNDERSTANDING THE SCIENCE OR REFUSING TO MASK OR GET VACCINATED THEMSELVES, PUTTING KIDS WHO CAN’T BE VACCINATED AT RISK JUST BLOWS MY MIND. >>> LET’S TALK ABOUT THE NEWS ABOUT THE J&J BOOSTER BECAUSE THE J&J SHOT, IT’S A SMALL PERCENTAGE OF THE MANY HUNDREDS OF MILLIONS OF DOSES NOW PUT OUT. PFIZER AND MODERNA IN THIS COUNTRY FAR IN THE LEAD. THAT’S IT, IT’S IMPORTANT. IT’S ONE SHOT. SHOULD THIS GIVE US SOME ENCOURAGEMENT HERE? BECAUSE NOW YOU HAVE ANOTHER OPTION WITH THE BOOSTER THAT RELIABLY ACCORDING TO THE DATA FIGHTS BACK AGAINST THE DELTA VARIANT. >> WELL, YOU KNOW, JIM, LET ME START BY SAYING WE HAVE NO CLINICAL EVIDENCE THAT YOU’RE SEEING MORE FAILURES WITH JUST J&J THAN WITH THE OTHER VACCINES. SO I THINK WE’RE COMING TO A PREMATURE CONCLUSION. WE HAVE NO DATA SAYING THOSE WHO GOT J&J ARE GETTING HOSPITALIZED MORE THAN THOSE WHO GOT PFIZER OR MODERNA. THE PROTECTION IS ABOUT THE SAME. I’M NOT VERY CONCERNED ABOUT THAT. WHAT WE SEE IN THE STUDIES, AN INCREASE IN ANTIBODIES, WE NEED A STUDY THAT TELLS US IT TRANSLATES TO BETTER PROTECTION FROM INFECTION AND DECREASE HOSPITALIZATIONS AND DEATH. AND THE CLINICAL OUTCOMES DATA SIMPLY NOT THERE. SO THIS IS ENCOURAGING NEWS, BUT AGAIN, I WOULD BE VERY CAREFUL ABOUT MAKING THE LEAP OF FAITH SAYING BECAUSE OF THIS THEREFORE THAT MEANS IT’S PROTECTIVE. >> FAIR ENOUGH. IT’S A SMART POINT. BY THE WAY, HAVING OPTIONS IS GOOD, NO QUESTION. >>> FINAL QUESTION, IF I CAN. WE HAVE A LOT OF CONCERNING DATA ABOUT WHAT THE DELTA VARIANT IS DOING, PARTICULARLY IN STATES WITH LOW VACCINATION RATES. WE HAVE SOME BETTER NEWS, THOUGH, RIGHT, WHERE WE SEE THE DAILY AVERAGE OF VACCINATIONS TWEAKING UP, THAT KIND OF THING. WE SEE A LOT OF SCHOOL DISTRICTS REQUIRING MASKS AS THE PUBLIC HEALTH GUIDANCE IS. ARE YOU SEEING ANY, ANY DATA THAT GIVES YOU AN INDICATION THAT THE COUNTRY IS RESPONDING TO THE DELTA SURGE IN A WAY THAT SHOULD ENCOURAGE US? I’M NOT SAYING THE THREAT IS GONE. YOU GET MY POINT, THOUGH, HERE. ARE THERE SIGNS THAT WE’RE GETTING A HANDLE ON THIS? >> WELL, YOU KNOW, WITHOUT DOUBT WE’RE SEEING MORE AND MORE PEOPLE VACCINATED. BUT AGAIN, THE PEOPLE VACCINATED TODAY ARE NOT GOING TO BE PROTECTED UNTIL SIX WEEKS FROM NOW. SO IT’S GOING TO TAKE SOME TIME. BUT I THINK PEOPLE ARE TAKING DE DELTA SERIOUSLY. I THINK THEY’RE REALIZING THIS IS SOMETHING THEY NEED TO BE CONCERNED ABOUT. I’M HOPING AS A RESULT OF THAT WE’RE STARTING TO SEE A FLATTENING OF THE CURVE, DELTA INCREASES IN SOME PLACES. EVEN FLORIDA IS BEGINNING TO SEE A LITTLE BIT OF FLATTENING WHICH MAY BE ENCOURAGING NEWS. THE REALITY IS DELTA IS BETTER. I WANT TO REASSURE IF YOU’VE BEEN VACCINATED, YOU REALLY ARE IN GOOD SHAPE EVEN WITH THE LOWER PROTECTION AGAINST INFECTION FROM DELTA. THERE MAY BE BREAKTHROUGH CASES BUT YOU’RE UNLIKELY TO BE HOSPITALIZED OR DEAD. THE PROBLEM IS PEOPLE WHO ARE NOT VACCINATED. IF I WAS NOT VACCINATED, I WOULD REALLY BE SCARED ABOUT THIS STRAIN. THIS IS REALLY HIGHLY TRANSMISSIBLE AND YOU CAN GET — YOU CAN END UP BEING VERY SICK. I CAN TELL YOU, WE HAVE OUR HOSPITALS FULL OF PEOPLE WHO HAVE NOT BEEN VACCINATED WHO ARE IN THE I.C.U., WHO ARE ON VENTILATORS. AND THIS IS REALLY — THIS IS THE TRAGEDY, RIGHT. >> THE VAST — THE DATA SHOWS THE VAST, VASTst VAST MAJORITY OF FOLKS GETTING SICK
