To fight the COVID-19 pandemic, various techniques have been developed. Vaccine development is high on their priority list, despite the fact that the duration of protection is unknown. Various vaccinations have been tested in clinical trials in various countries, with promising outcomes. The vaccinations' protective efficacy as well as their short- and long-term negative effects are key concerns. As a result, assessing the preventive efficacy and dangers of vaccination is critical for COVID-19 management through herd immunity on a worldwide scale. This study examines the most recent data on...

The term "nanoparticle" refers to solid particles or particulate dispersion with sizes between 10 and 1000 nm. The medication is either dissolved, trapped, enclosed, or joined to a nanoparticle matrix. Nanoparticles, nanospheres, or nanocapsules can be produced depending on the technique of preparation. Unlike nanospheres, which are matrix systems in which the drug is physically and evenly spread, nanocapsules contain the drug inside a chamber that is enclosed by a special polymer membrane. The ability of biodegradable polymeric nanoparticles to circulate for an extended period of time to...

Pour lutter contre la pandémie de COVID-19, diverses techniques ont été mises au point. La mise au point d'un vaccin figure en tête de liste de leurs priorités, malgré le fait que la durée de la protection est inconnue. Diverses vaccinations ont été testées lors d'essais cliniques dans différents pays, avec des résultats prometteurs. L'efficacité protectrice des vaccins ainsi que leurs effets négatifs à court et à long terme sont des préoccupations majeures. Par conséquent, l'évaluation de l'efficacité préventive et des dangers de la vaccination est essentielle pour la...
