@ChildrenGrowingUpTooFast and others.
I absolutely hate the attitude on here of "I can't be doing with anti-vaxxers". And questioning people's intelligence without knowing the circumstances.
Life is not completely black and white. (Refuseniks BAD, Vaccine GOOD). Vaccines for different illnesses have made some people ill before . Some people have died shortly after the covid vaccines. Not many , but enough for our government to offer an alternative to AZ for certain demographics and for other countries to deem many of them not yet fully safe. Some people have specific health conditions that might make the vaccine ill advisable. Others may have a fair idea of their likely risk of being admitted to ICU if they caught Covid (fleetingly small in some demographics i.e the under 40s) versus their small chance of an adverse reaction to a vaccine .
It is a fact that the average person under 30 has a miniscule risk of a fatal blood clot from the AZ vaccine for example. But that risk is still a little MORE than the risk of dying of covid in the same under 30 demographic. Hence the UK government offering an alternative to that demographic.
For older people whose risk of suffering badly from covid is far higher, the AZ vaccine is recommended. The risk of clotting is worthwhile because the risk of covid is higher for them.
Before anyone calls me misinformed , or an anti vaxxer, let me say now that I am a medic and my husband is a scientist who synthesises chemical compounds for the treatment of virus and disease. Our friends are in similar industries. We both did have the vaccine, but we deliberated, and there are many knowledgeable people we know who chose not to. Common reasons have been that the long term safety of the vaccines and their effects still aren't known, and also a family history of heart conditions which could be affected by these vaccines.
Ultimately it's a personal decision for each of us to make and personally I doubt the intelligence of anyone who isn't able to see that.
If you are worried about covid and want the vaccine, have it. I did. But why on earth would you be certain that anything on this planet , let alone a new man made vaccine , is so completely safe that you'll scoff at anyone who is unsure ?
