I just recently got covid for the first time and my PD symptoms have worsened dramatically, both my primary and neurologist and nurses told me covid and or the vaccines will affect the weakest part of your body and boy it has

With the original vaccine, there were only a few companies that got approved to make and sell Covid shots. I think the same few are also responsible for the boosters, since they have a proven record. The most common manufacturers in the US are not the same as the ones used in the UK. Here most of us got Moderna or Pfizer vaccines, but in the UK it was mostly Astra Zeneca and GSK/Sanofi. I think they pretty much work the same though.

You are very welcome Graham. Please let me know what you learn. You have peaked my interest now so I'd like to know more.

Many thanks Maria for your trouble,I am grateful for your efforts even though you couldn't find anything.
I will ask the question of my local Parkinsons Clinic and publish here what they tell me as there may be other Brits or Europeans who are members or readers.

This is aan interesting question Graham. I looked it up and could not find any information about any versions of this vaccine being approved worldwide. It seems that countries who have regulatory agencies like the FDA in the US only dispense vaccines approved in that specific country. I could not find information on international differences between the various sources or the efficacy of the various vaccines. Sorry I could not be more helpful.
