WNYW-TV (New York, NY) - THE 5 O'CLOCK NEWS

bring it down. >> fox five health news. president trump signed an executive order separating the measles, mumps mumps and rubella vaccine into three separate single disease shots and cuts the the national vaccine recommendations two injections against 11 diseases instead of 18. >> and joining us now is doctor purvi parikh, clinical assistant assistant professor of immu immunology and infectious disease at nyu langone. doctor great to see you. thanks to you so much joining us. >> thank you for having me. >> so these separate shots even availablele in the u.s. break down this executive orde and the reasoning behind it. >> right so, you know, most of of the pediatric vaccines that are recommended come come in combinedombined form. so you can get two or even three vaccines with one needle, which is very convenient, especially for young babies and young children, that you don't hav have to poke them multiple times, multiple needles. needles. and it's been t way since the 70s. the reasoning behind it is unclear because we now of data showing showing from the american academy of pediatrics pediatrics department of health that these vaccines are safe, they're effective, and the save lives, especially amongst our younges and most vulnerable individuals. >> you kno i've seen a lot of concerns from people saying, hey, wou you get would one copay if you had to go back back three times?here's concerns parents maybe skipping it all together. if it was t separate doctor's visits,isits, it's tough to get into a doctor as is. how do you see this playing out? and is the order doesn't actually have thee rule behind it. right. it's more more him just saying, this is something i would like to see happen. >> it would be complicated complicated too, because currently most of these exist ase shots like mmr, mmr, for example, doesn't doesn't exist as three separate vaccines as it is is now. so it would take a lot of time. trials trials would have to be to show that equal equal safety and efficacy. it had to get approved by the fda. so i don't see occurring overnight. and yes, yes, there is that concern of vaccine hesitancy. you know, parents may not want to to take their kids inin for multiple visits or forget skip visits. and then that delays the time until children are protected,ed, which is especiall especially dangerous given that we have measles outbrea right now. so even what current recommendations are is that some pediatricians are giving the mmr a little bit early. currently, given this un unprecedented amount of measleses cases that we've seen for the first time in, you know, over three three decades. so so that is a concern. and as a parent myself, myself, of course,rse, i would rather have my child get less pokesm the needle and have to go to the doctor lessor less times and then get, you know,w, protected faster rather than a longer longer period. >> yeah. what's likelihood that the manufacture manufacturers go along with this too, because they don't that much incentive to create three separate shots? >> yeah. i mean, likely they won't. w we know that vaccine development is very expensive. labor intensive takes time. so yeah. right. as you said, the in isn't there. weon't even know if it be available in thisn this form. so there's many unanswered questions at this point.
