The SMC team produces explanatory articles on topical issues to answer society’s questions, with the necessary context and depth.
On 27 April, the WHO reported 151 cases of salmonellosis in 11 countries, caused by the consumption of 'kinder eggs' or other contaminated products of the same brand. In Spain, two cases have been confirmed.
In recent weeks, several countries have detected unusually severe cases of hepatitis of unknown origin in healthy children. Some of the patients have required transplantation and at least one of them has died. Researchers are working on several hypotheses around an adenovirus, but the matter is still shrouded in uncertainty.
The Intergovernmental Panel on Climate Change (IPCC) is meeting between 21 March and 1 April to approve the study on measures to curb the climate crisis, on which more than 200 authors from all over the world have been working for three years. The text will be published on 4 April.
The European spacecraft that was to investigate whether Mars harboured life in the past will no longer fly. The satellite that was to study dark energy in the universe is delayed and a robotic telescope at the Teide Observatory stops working. Europe used to spend tens of millions of euros on scientific collaboration with Russia. But no more.
More than two million doses of the vaccine from US company Novavax are expected to arrive in Spain soon. Nuvaxovid, or NVX-CoV2373, became the fifth vaccine approved in Europe against covid-19 on 20 December. We tell you how it differs from those already available, how it is produced and why it is especially important for countries with fewer resources.
The WHO recommends keeping an eye on the BA.2 variant of Omicron because it is spreading, but it does not appear to cause more serious disease or escape vaccination. Don't be fooled by its evocative nickname: it is perfectly detectable. The misconception that tests do not identify it was propagated by a headline that was corrected.
In Spain, since 13 January, the booster vaccination against covid-19 has been recommended for the general adult population. 78.8 % of those over 50 and 88.9 % of those over 60 have already had it, said the Minister of Health yesterday. If those who are missing have doubts, here we try to solve them.
The terms "endemism" and "seasonality" are increasingly used to refer to the covid-19 pandemic. They are sometimes incorrectly associated with the severity of the disease or with the premature end of the pandemic. What do they mean? Does SARS-CoV-2 fit these definitions? Will it ever do so thanks to vaccines?
The first solid work on the ability of vaccines to stop infection with the omicron variant, which has just been published, reinforces the need for a third dose. Experts recall, however, that the aim of vaccines was never to stop infection, but to prevent severe disease. We summarize what is known so far about it.
The recommendation is to vaccinate children from 5 to 11 years old with the vaccine approved in Europe for this age group, Comirnaty (Pfizer) with one third of the dose used in children over 12 years old. But parents still have doubts. Here we answer the classic ones (safety, risk/benefit) and other more specific ones: allergies, genetic syndromes, high-risk individuals...
