(Reuters) - A nurse in California tested positive for COVID-19 more than a week after receiving Pfizer Inc's vaccine, an ABC News affiliate reported https://bit.ly/2L8iBel on Tuesday, but a medical expert said the body needs more time to build up protection.

Matthew W., 45, a nurse at two different local hospitals, said in a Facebook post on December 18 that he had received the Pfizer vaccine, telling the ABC News affiliate that his arm was sore for a day but that he had suffered no other side-effects.
