LISBON: Portugal has vaccinated 86 percent of the country's population against the coronavirus, but the prime minister warned on Tuesday (Wednesday in Manila) that the latest infection surge across Europe compels the Portuguese government to consider precautionary measures. 'We can't ignore the signs,' Prime Minister António Costa said of the European Union's growing number of new confirmed cases. 'The later we act, the greater the risk.' Costa has convened a Friday meeting of health experts to assess what measures may be required. After that, he plans to meet with the leaders of opposition parties.
