Leading experts have warned delaying the second dose could have a “catastrophic” impact on the efforts to end thecrisis. They fear the delays to the second jab could foster vaccine-resistant mutations in the virus, making it harder to end the pandemic. In December the Government announced the second dose would be given towards the end of 12 weeks rather than in the previously recommended 3-4 weeks.
They haven't tested this vaccine 3 months apart if the science says 21 days apart then 21 days it should be. If you can't do it properly in the first place you might as well not bloody bother.
Doubt it
