Nurse tested positive for coronavirus in US days after receiving Pfizer-BioNTech vaccine. The 45-year-old works in the emergency departments of a hospital in the California city of San Diego and was vaccinated on December 18. Experts assured that it was not “something unexpected”.

The health worker, identified as Matthew W., said to a local television channel associated with ABC News, that he had been vaccinated with the first dose in mid-December and that the only side effect he suffered was a little pain in his arm after the needle stick.
