Sanofi is enriching the provision of information on our membership website to deliver information to you in a timely manner. With the spread of COVID-19 infection, we will further enhance the content of the website and provide information in a new era. Please register with the website on this opportunity. The site is full of useful information that is regularly updated for allergic diseases, which are often associated with multiple diseases, too. (* We introduced a system that eliminates unnecessary email newsletters and only delivers the information you need.)
