When referring to the vaccines from a UK perspective they are not "experimental" as categorized by the U.S. FDA under the EUA. The MHRA gave full approval to all three vaccines in the UK (Janseen later this year.)

The re-alignment of the Yellow Card Scheme does not mean that there are more/new side effects from the COVID-19 vaccines. Also, similar to the reporting database in the U.S. (VAERS) adverse as the letter points out - events do not indicate that the vaccine caused them nor that the vaccine is unsafe. These reports are starting points for investigations.

I read the letter and was OK with it up until Lawrie started making claims against the data without actually performing the research on each entry. She then started to leap to the conclusion that they are unsafe for humans. Lawrie directly contradicts herself.

Absolutely agree that more expedient investigation needs to take place to understand if there is any correlation. Maybe even government and 3rd party analysis.

I urge you to read the following article for another take on the letter:
Yellow Card scheme for adverse events does not suggest any new side effects of COVID-19 vaccines
