So that’s a ‘no’ on weighted data (adults more likely to notice side effects and attribute to vaccine), and ‘no’ on comparative ratio to vaccine doses over the same time period? And measuring increased awareness of yellow card over the last 12 months from a November 2020 baseline?
Without all that it’s fairly hard to draw conclusions on safety or determine whether the numbers are ‘scary’ or not.
MHRA says the reporting is 3-6 per thousand; I’ve not seen comparators yet so grateful if you can share any. They also say:
For all COVID-19 vaccines, the overwhelming majority of reports relate to injection-site reactions (sore arm for example) and generalised symptoms such as ‘flu-like’ illness, headache, chills, fatigue (tiredness), nausea (feeling sick), fever, dizziness, weakness, aching muscles, and rapid heartbeat. Generally, these happen shortly after the vaccination and are not associated with more serious or lasting illness.
We’re in the midst of the most publicised vaccine rollout in history, involving huge numbers of people who don’t usually have any vaccines. Awareness of Yellow Card will have increased if only through news media reporting of Yellow Card events.
Some people will ascribe entirely incidental events to their vaccines, because as humans we look for patterns and reasons for things. There will have been a large number of strokes this year within a month of people having a vaccine, for example, because there are always large numbers of strokes and when you’re vaccinating millions a month there will be some that fall near a vaccination.
