Patient reported that her body was also sensitive to chemicals and such in general. However, this vaccine put me in bed for days with body aches so severe I couldn't touch my skin, headaches was so bad I contemplated if I needed to go to the ER.  Patient concern was the elevated WBC's that have never come down.  Company Comment This spontaneous case concerns a 43-year-old female patient with no medical history reported who experienced the unexpected events of heart cell irregular (AESI), pain, white blood cell count increased, swelling, diarrhoea and other expected events 9 days after 2nd. dose of mRNA-1273 vaccine. Concomitant medication details nor Treatment details were reported On 04-Feb-2021, White blood cell count was elevated  to 12.43 thousand per cubic millimetre. At the time of the report, the events had not resolved.    The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.
