Buenos Aires City Health Minister Fernán Quirós has confirmed fears of mounting numbers of Covid-19 cases, saying that the community circulation of the Delta coronavirus strain was not a matter of if but when.
Once that happens, the percentage of infection will double every 10 days, he told María Laura Santillán on the La Mañana de CNN radio programme, adding that accelerating the application of second vaccine doses would be fundamental since a single dose immunised little more than a third of recipients with a booster dose taking protection up to the 60-90 percent range.
Quirós said that the Ministry was evaluating schemes of combined vaccines while insisting on clinical tests ahead of any recommendation.
But he noted that an AstraZeneca/Pfizer combo had already been demonstrated to be safe and even improving on either one separately while for some other vaccines, not even a second dose was sufficient.
