Vaccinated or know someone who is? Check the batch number.

It is estimated that approx 99.5% of Covid-19 vaccine batches have few adverse events associated with them.

However, adverse events appear to be concentrated in around 1 in 200 of the batches. Many of these batches listed in VAERS (USA) have a GB-MHRA prefix. This is a list of the top 300 toxic Pfizer UK batches. Eg "EW8904: 658", the batch has 658 Adverse Events. The batch number is written on the vaccination card or certificate.

Note: there are also many people who have taken these batches and are not reporting health problems. Doctors are the media are silent on this issue, even though the data is public.
