RIGHT NOW, A 4:45, WE TURN TO FIVE ON YOUR HEALTH AND RFK JR IS ASKING THE CDC TO LOOK FOR NEW MEASLES TREATMENTS. THE HEALTH AND HUMAN SERVICES SECRETARY WANTS THE CDC TO CONSIDER MEDICATIONS AND ALTERNATIVE THERAPIES, INCLUDING VITAMINS. THE CDC RECOMMENDS THAT THE MEASLES VACCINE HAS THE MOST EFFECTIVE PREVENTIVE MEASURE. BUT KENNEDY SAYS FOR THOSE WHO CHOOSE NOT TO GET THE SHOT, THERE SHOULD BE ANOTHER OPTION. IT IS A IT鈥橲 A IT鈥橲 A HOT BUTTON. IT鈥橲 A TALKING POINT. AND DOCTOR TODD ELLERIN IS HERE TONIGHT. CHIEF OF INFECTIOUS DISEASES, SOUTH SHORE HEALTH, TO TALK TO US ABOUT THAT. NOW, NOW, YOU HAVE SAID BEFORE, RIGHT? AND CORRECT ME IF I鈥橫 WRONG, THAT THAT TWO DOSES OF THE MEASLES VACCINE ARE 97% EFFECTIVE AT PREVENTING INFECTION AND ONE DOSE IS STILL 93% EFFECTIVE, RIGHT? SO THOSE NUMBERS ARE PRETTY STRONG. HAVE YOU SEEN ANYTHING ELSE COME CLOSE? NOTHING ELSE COMES CLOSE. REMEMBER, IT鈥橲 THE MEASLES VACCINE THAT BROUGHT THE UNITED STATES TO REALLY ITS ELIMINATION STATUS OF MEASLES BACK IN 2000. SO THERE鈥橲 NO BETTER PREVENTION. WITH THAT SAID, YOU KNOW, I AGREE THAT WE DO NEED BETTER THERAPIES FOR MEASLES, YOU KNOW, ESPECIALLY FOR PEOPLE THAT CAN鈥橳 GET THE VACCINE, LIKE IMMUNOCOMPROMISED PATIENTS WHO CAN鈥橳 GET IT. SO SO RIGHT NOW THERE鈥橲 A LITTLE CONFUSION. VITAMIN A CAN TREAT PATIENTS WITH SEVERE MEASLES, ESPECIALLY CHILDREN IN THE HOSPITAL. BUT THAT鈥橲 VERY HIGH DOSES OF MEASLES, NOT THE VITAMIN. THE VITAMINS DON鈥橳 PREVENT MEASLES. SO SO LET鈥橲 TURN TO ANOTHER VIRUS WITH A VACCINE. AND THAT鈥橲 THE FLU. WE JUST GOT THROUGH A BAD FLU SEASON HERE IN THE UNITED STATES. THE CDC NOW SAYS TAKE A LOOK AT THE NUMBERS. 216 KIDS HAVE DIED IN THE US. THAT鈥橲 216 TOO MANY. BUT HOW DOES THAT NUMBER COMPARE TO OTHER YEARS? THAT鈥橲 THE BIGGEST NUMBER IN 15 YEARS SINCE THE SWINE FLU, WHEN THERE WAS A LITTLE OVER 300 DEATHS. WE HAVEN鈥橳 HAD ANYTHING LIKE THAT. IT鈥橲 INCREASED SINCE LAST YEAR. THERE WAS ABOUT 207 DEATHS. THE BIGGEST PROBLEM IS THAT WE鈥橵E SEEN CHILDHOOD VACCINATION, PEDIATRIC VACCINATION DECLINE FROM ABOUT 64% FIVE YEARS AGO TO 49% THIS YEAR. NOW, WE DON鈥橳 KNOW HOW MANY DEATHS IN THESE KIDS WERE VACCINATED OR UNVACCINATED, BUT I WILL SAY LAST YEAR AND MOST YEARS, ABOUT 80% OF THE DEATHS FROM FLU IN CHILDREN ARE IN UNVACCINATED. SO I JUST WANT TO EMPHASIZE 80%. THAT鈥橲 A LARGE NUMBER. AND LET鈥橲 GO OVER IT AGAIN BECAUSE IT鈥橲 WORTH REPEATING. YOU MENTIONED, WHAT, FIVE YEARS AGO, THE VACCINATION RATE FOR KIDS IN THE UNITED STATES WAS 64%. THIS SEASON IT鈥橲 UNDER 50%. THAT鈥橲 A SIGNIFICANT DROP. SO. SO IT IF IT GOES FROM 64 TO 49, WILL IT GO EVEN LOWER. AND THE CONCERN IS AND THIS IS THE CONFUSING PART, YOU CAN GET YOUR FLU SHOT, YOU CAN GET YOUR COVID VACCINE. YOU CAN STILL GET THOSE ILLNESSES. BUT WHAT WE鈥橵E SEEN IS THAT THOSE ILLNESSES TEND NOT TO LEAD TO HOSPITALIZATIONS OR DEATHS. SO THAT鈥橲 THE YOU KNOW, THAT鈥橲 WHAT WE鈥橰E TRYING TO SORT OF REALLY GET HOME. BUT YOU KNOW, WE KNOW THERE鈥橲 SO MUCH, YOU KNOW, MIXED MESSAGING AROUND THESE VACCINES THAT IT鈥橲 A REAL PROBLEM. IT鈥橲 INTERESTING HOW WHAT, 25 YEARS AGO IS VIRTUALLY ELIMINATED. NOW, 25 YEARS LATER, WE鈥橰E TALKING ABOUT TRYING TO VIRTUALLY ELIMINATE IT AGAIN. RIGHT. WE NEED TO RIGHT. WITH WITH MEASLES SPECIFICALLY. IT鈥橲 O
