The new tailored doses against Omicron have arrived just in time for the upcoming autumn and winter wave. Although we do not know which variant will circulate in the coming months, these vaccines are safe and will help reduce transmission in what could be difficult months from a care pressure point of view.

Regulatory agencies in the US and Europe - the FDA and the EMA - have licensed vaccination against Omicron focusing on different variants and sub-variants. Different procedures and studies in humans and animals have informed the agencies' decisions. Experts hope that these new doses will provide sufficient protection this autumn and winter to mitigate the impact of the next wave.

The European Medicines Agency (EMA) has authorised the administration of monkeypox vaccine intradermally rather than subcutaneously.

The European Medicines Agency (EMA) is still considering the approval of Hipra's SARS-CoV-2 vaccine. In mid-May, Hipra said it was ready to "have the vaccine available in a few days" following EMA approval, which it expected by the middle of this year, but which is being delayed until at least after July, as Elia Torroella, Hipra's R&D and Registration Director, explained at a breakfast briefing organised by the company today.

The high temperatures have led to an increase in cases of heat stroke, a serious disorder that requires urgent medical attention.

Communicating outbreaks of infectious diseases is not easy, especially when they affect population groups that may face discrimination. Cases of monkeypox among men who have sex with men remind us of the importance of reporting without stigma.
