The Joint European Torus (JET) has achieved a relevant scientific milestone related to energy production from nuclear fusion reactions. The results confirm some of the technological options selected for the large international ITER experiment. Spain has proposed to build a scientific facility in Granada to develop materials with which to build future reactors.

The Spanish Society of Public Health and Health Administration calls for the creation of an institution "that prepares us to protect the health of our population in the face of the current pandemic, future pandemics and current health challenges".

The dream of obtaining electrical energy from the fusion of two atomic nuclei is a little closer. Results obtained with some of the most powerful lasers on the planet show that one of the strategies to achieve this, nuclear fusion by inertial confinement, works as predicted 50 years ago.

In the covid-19 pandemic, there is no evidence to justify closing classrooms to interrupt transmission and protect the health of children. On the other hand, there is evidence of the harm caused to them by dropping out of school.

The pandemic has shown us that neither science nor engineering alone is capable of solving a problem in real time when the crisis is global, when local interventions are costly and of limited effect, when we have to act without having all the information.

A survey conducted by the COSMO-Spain team to find out the reasons why some people have not yet been vaccinated showed that most of them fear that vaccines are unsafe and their side effects. These results highlight the importance of rigorous communication of drugs that are considered safe and effective by all studies and agencies.

The misleading presentation of hospitalization data, ICU admissions or deaths in vaccinated and unvaccinated persons that we are seeing these days in some media and social networks are generating confusion about the effectiveness of these preparations.

A clinical trial in Brazil evaluated the effectiveness of a depression drug versus placebo in reducing the risk of hospitalisation for SARS-CoV-2 infection. Administration of 100 mg twice daily for ten days to high-risk outpatients with early diagnosis reduces the need for hospitalisation.

With the goal of vaccines reaching a huge part of the European population achieved, we must provide scientific evidence and action to ensure that all people have access to immunisation. We will find herd immunity by vaccinating and monitoring infections now more than ever.
