Africa-Press – Benin. <\/strong><\/span>Une e\u0301quipe de chercheurs britanniques a re\u0301cemment mis au point un moyen d\u2019inoculer un vaccin sans avoir recours a\u0300 une seringue. Pour re\u0301aliser cette prouesse, les scientifiques exposent le me\u0301lange liquide a\u0300 des ultrasons pour une administration tout en douceur, de quoi ravir les personnes ayant la phobie des seringues.<\/p>\n

Une alternative aux seringues lors d\u2019un vaccin<\/p>\n

Pour rappel, la be\u0301le\u0301nophobie n\u2019est autre que la peur extre\u0302me des gestes me\u0301dicaux qui impliquent l\u2019usage des seringues hypodermiques et des injections. Incluse en 1994 dans le Manuel diagnostique et statistique des troubles mentaux (DSM-IV) en tant que phobie spe\u0301cifique de type sang-injection-blessure, la be\u0301le\u0301nophobie concernerait environ 10 % des adultes, rien qu\u2019aux E\u0301tats-Unis. Toutefois, ce chiffre est sans aucun doute sous-estime\u0301 puisque bon nombre de patients atteints par ce trouble e\u0301vitent toute intervention me\u0301dicale.<\/p>\n

Dans un communique\u0301 publie\u0301 le 3 de\u0301cembre 2023, un doctorant en me\u0301decine a\u0300 l\u2019Universite\u0301 d\u2019Oxford (Royaume-Uni) a pre\u0301sente\u0301 une possible alternative aux seringues, notamment dans le cadre de l\u2019administration de vaccins. Pour ce faire, Darcy Dunn-Lawless et son e\u0301quipe ont me\u0301lange\u0301 des mole\u0301cules de vaccin et de minuscules prote\u0301ines en forme de bol, avant d\u2019appliquer le tout sur la peau de souris. Ensuite, le me\u0301lange a e\u0301te\u0301 expose\u0301 a\u0300 des ultrasons durant environ 90 secondes.<\/p>\n

Dans l\u2019attente de recherches comple\u0301mentaires<\/p>\n

Dans un premier temps, les ultrasons ont pousse\u0301 le me\u0301lange a\u0300 l\u2019inte\u0301rieur de l\u2019e\u0301piderme dans lequel les prote\u0301ines en forme de bol ont ge\u0301ne\u0301re\u0301 de petites bulles de vaccin. Ensuite, les bulles ont e\u0301clate\u0301 sous l\u2019effet des ultrasons, libe\u0301rant le vaccin dans l\u2019organisme. Selon les chercheurs, cette me\u0301thode est plus superficielle qu\u2019une injection de vaccin dans un muscle, mais serait tout de me\u0302me suffisante pour procurer une immunite\u0301 aux patients. Les re\u0301sultats ont montre\u0301 que si la dose de vaccin e\u0301tait 700 fois moins importante que lors d\u2019une injection classique, les souris ont produit davantage d\u2019anticorps.<\/p>\n

Pour les auteurs de l\u2019e\u0301tude, le phe\u0301nome\u0300ne s\u2019expliquerait par une pre\u0301sence plus importante des cellules immunitaires dans la peau pluto\u0302t que dans les muscles. Toutefois, il n\u2019existe encore aucune certitude, si bien que les me\u0301decins travaillent toujours sur la question. Les chercheurs vont tenter de mieux quantifier l\u2019explosion des bulles de vaccin en mesurant les sons produits pour un meilleur contro\u0302le de leur re\u0301gularite\u0301 et donc de leur efficacite\u0301.<\/p>\n

La vaccination par ultrasons est encore tre\u0300s loin d\u2019une de\u0301mocratisation pour une application sur les humains. En revanche, dans le cas ou\u0300 la poursuite des travaux valide la technologie, son apport sera conside\u0301rable. Kate Edwards, professeure a\u0300 l\u2019universite\u0301 de Sydney (Australie), estime en effet que cette technique pourrait pousser les patients les plus re\u0301ticents a\u0300 se faire vacciner, notamment les be\u0301le\u0301nophobes.<\/p>\n
