![]() Eventually, herd immunity will be obtained through both immunity acquired by infected individuals and immunity acquired by vaccines. Natural immunity, on the other hand, is more random because it varies according to the severity of the disease and the presence or absence of symptoms. After the first vaccine injection, we already obtain 50% protection and almost 95% seven days after the second. A.: We believe that immunity induced by vaccines will be stronger and more durable than that induced by infection. What is the difference between the immunity induced by Sars-Cov2 contamination and that provided by vaccines?ī. Even if it would then have to be validated by regulatory agencies, we would progress much faster than with conventional vaccines. The other advantage of these innovative messenger RNA technologies is that the vaccine can be very easily modified to adapt it to a new variant. The fight against Covid-19 was the opportunity to demonstrate for the first time the impressive efficacy of these vaccines. Tested in early human clinical trials, this type of vaccine did not reach the efficacy phases simply because we did not have the pressure that this epidemic is generating today. This vaccine technology has been developed for several years in other applications, for example, against influenza or the Zika virus. These novel vaccines are based on thirty years of extremely rigorous research into the therapeutic use of messenger RNA. A.: The AstraZeneca/Oxford viral vector vaccine has the advantage of being inexpensive and can be stored in the refrigerator, unlike the vaccines of Moderna and Pfizer/BioNTech, which can only be stored at very low temperatures. What are the strong points of these new-generation vaccines?ī. Let’s talk the Pfizer-BioNTech, Moderna and AstraZeneca vaccines. A series of questions and answers with the public, via chat, will conclude these sessions. The presence of colleagues from the Faculty of Arts and Humanities at Sorbonne University and the Faculty of Law at the University of Paris will enable us to address the history of vaccine hesitation, the issue of the vaccine passport and freedom of movement, as well as that of communication in times of crisis.Įach session will begin with a brief presentation by leading experts followed by a debate on scientific and societal issues. ![]() A.: The conference will be broken up into three sessions: the first will focus on available vaccines, the second on the vaccine strategy in France and the last on more societal issues. What will be the main themes of this conference?ī. ![]() Organized in the form of a webinar, this conference is also an opportunity to debate the questions raised by both specialists and a large part of the population. It therefore felt important for us to give them a voice in order to provide solid information to the entire academic community, journalists and the general public. Stakeholders in this fight against Covid-19, Sorbonne University and the University of Paris include a number of experts who participate in the definition of recommendations and the vaccine strategy in France. ![]() What is its objective?īrigitte Autran: In a context of information overload where it is difficult, even for healthcare professionals, to distinguish what is true or false, universities have a major role to play in disseminating quality information and restoring rigorous thinking. You are organizing a major conference on vaccination on January 29th which will be available to watch online. ![]()
