Virus infections have been increasing steeply following Christmas and New Year, putting pressure on Spain's public health system.
Spainโs Defense Ministry has been the latest governmental department to launch an internal inquiry to find out if the military top brass dodged coronavirus vaccine protocols by receiving a jab before their turn.
The rollout is suffering delays due to a shortage of deliveries by Pfizer-BioNTech, currently the main supplier of vaccines.
Having administered over 86% of the 1.1 million vaccine doses received, several regions have halted new vaccinations until fresh supplies arrive.
Guerrero, who is a physician himself and has diabetes, said at a press conference Thursday that he accepted getting the jab because his staff insisted.
