Based on current available information and the temporal association between product use and the start date of the events a causal relationship cannot be excluded except for  the event of hypokalemia which is unlikely.   Most recent FOLLOW-UP information incorporated above includes: On 27-Apr-2021: Follow-up received on 27apr2021: updated event and possible causality. Reporter does not think the blood pressure and pulse issues related to vaccine; Sender's Comments: Based on current available information and the temporal association between product use and the start date of the events a causal relationship cannot be excluded except for  the event of hypokalemia which is unlikely.
