Do you want proof the Delta variant is an extremely weak variant?
In the unvaccinated under 50's there were 52,846 cases and 6 deaths.
This works out as a death rate of just 0.011% (38% less lethal than the flu)

Using this data, if the entire population of under 50's were infected at the same time tomorrow, there would be just 4,400 deaths and we would have 59% of the population with herd immunity.

There are just over 40,000 million people aged under 50 in the UK, (59% of the population)

Forward this to any healthcare workers being coerced to take the injection.

The Facts.

1. It isn't law for healthcare workers to take the vaccine.
2. It isn't due to become law until October.
3. It only applies to CQC registered care homes.
4. To become law, it has to pass parliamentary approval which won't be easily passed.
5. If it does become law, there will still be legal challenges, so hold tight.
6. If it does become law, there is a 16 week grace period which means you won't be obliged to take the injection until February 2022.
7. Phobia of needles is a medical exemption.
8. Anxiety of vaccination is a medical exemption.
9. Any employer pushing you to take an injection before it becomes law is harassing you.
10. Believe it or not, the employer will only need verbal confirmation that you've been injected according to Gov guidelines drawn up.

Keep a diary of every interaction.
