A few nations are going ahead with mixing and matching Covid-19 vaccines. The experimentation stems from the fear over the spread of the Delta variant.
On May 9, the current state of alarm that is in place in Spain will expire, meaning that the countryâs regions â which are in charge of implementing coronavirus restrictions â will no longer be protected by a legal framework that avoids their measures being challenged in local courts. While the fourth wave of the epidemic in Spain is proving to be under control, for the most part, the regions are counting on having to maintain restrictions after May 9 in order to avoid further spread of the virus. In fact, some have even called on the central government to extend the state of alarm beyond that deadline.
