The number was reached with the vaccination of Maria Helena Lordelo, 64 years old, born in Póvoa de Varzim, who received the drug at 12:30pm, administered by nurse Ana Denise Silva, in the vaccination centre of the town.

Speaking to the Lusa news agency, the Secretary of State for Health, Diogo Serras Lopes, underlined the acceleration of the vaccination process, at a time when more vaccines are beginning to be available to the population. "It took more than two months to inoculate the first million vaccines, 33 days for the second, 19 days for the third. Now, we have reached 4 million in just 14 days. This is evidence that our efforts to protect the greatest number of Portuguese in the shortest period of time are having an effect", said the minister.

According to information from the Ministry of Health, of the four million vaccines administered in Portugal, about 2.9 million are first doses and 1.1 million are second doses, including the 18,000 vaccines from Janssen already administered. Thus, mainland Portugal already has more than 36 percent of the adult population already vaccinated with one dose.
