US researchers have designed an intranasal vaccination device that is capable of delivering immunising proteins through the mucosal surface. The research, published in Science Translational Medicine, shows that strong antibody responses against viruses such as HIV and SARS-CoV-2 have been achieved in mice and non-human primates.
Results from a survey of more than 39,000 menstruating individuals reveal that 42% experienced heavier bleeding after SARS-CoV-2 vaccination. Among the most likely groups were pre-menopausal women, Hispanic or Latina women, those who had been pregnant, and those with conditions such as endometriosis and polycystic ovary syndrome.

A paper published today in the journal Circulation concludes that acute myocarditis is a rare complication in patients hospitalised with covid-19 and that the severity of its prognosis depends on the simultaneous presence of pneumonia.
The European Medicines Agency (EMA) and the European Centre for Disease Prevention and Control (ECDC) consider it too early for the general population to receive a fourth dose of covid-19 mRNA vaccines. Both agencies do agree that people over 80 years of age should receive it because of their increased risk of severe disease.
Two studies published in The Lancet Infectious Diseases confirm that covid-19 vaccines offer additional protection for those already infected with SARS-CoV-2, especially against severe disease.
Reporting on vaccines is not easy, but in recent years many journalists have had to navigate studies and reports full of new terminology and concepts. In this guide, we attempt to clarify some of the most important points for accurate reporting on these medicines.
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.
