Less than a year after the first detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), vaccines have been approved for routine use in numerous countries and have already been used in mass vaccination programs. Vaccines include the mRNA BNT162b2 and mRNA 1273. Allergic reactions and anaphylaxis account for a substantial proportion of the adverse reactions to these vaccines observed to date, but overall they are rare. ⋯ This is followed by a discussion of the therapeutic approach to anaphylactic reactions, as well as the drugs and medical supplies required to treat them. It is important to note that any vaccinee may be affected by anaphylaxis, regardless of whether or not allergic diseases are already known. Therefore, every vaccination site and every vaccinator must be prepared to recognize and treat severe allergic reactions.

A genetic influence on blood pressure was demonstrated more than 100 years ago and a simple Mendelian inheritance was initially presumed. Platt and Pickering conducted a lively debate on this topic. Platt favored the idea that a single gene or only a few genes were responsible for high blood pressure. ⋯ A multitude of novel physiological mechanisms were explained by this. These findings will become therapeutically important. Therefore, it is incumbent upon clinicians to be optimally informed about these research results.

Arterial hypertension along with a number of dietary risk factors top the global mortality statistics for noncommunicable diseases. The so-called Western diet and an increasingly sedentary lifestyle are partly responsible for the high prevalence of hypertension. ⋯ While extensive evidence has been generated in recent decades and guidelines emphasize healthier diets, implementation of dietary modifications remains a challenge in everyday clinical practice. Information and education as well as medical and nutritional support for patients can help to implement measures, such as weight and sodium restriction in the long term to improve the prognosis of patients with hypertension.
