While many people want an injection as soon as possible, others are worried about putting something unknown into their bodies. Safety trials begin in the lab, with tests and research on cells and animals, before proceeding to human studies.
The principle is to start small and only move to the next phase of testing if there are no exceptional safety concerns.
What’s in the Covid vaccines?
Pfizer/BioNTech’s vaccine (and Moderna’s) uses little bits of genetic code to trigger an immune response, and is called an mRNA vaccine.
It does not changes in human cells, but merely presents the body with instructions to develop immunity to Covid.
The Oxford AstraZeneca vaccine uses a harmless virus altered to look a lot more like the pandemic virus.
Vaccines sometimes contain other ingredients, like aluminium, that make the vaccine stable or more effective.
Will a vaccine make me ill?
There is no proof that any of these ingredients cause damage when used in such small amounts.
Vaccines do not give you a disease. Instead, they teach your body’s immune system to recognise and fight the infection they have been designed to protect against.
Some people do suffer minor symptoms after being vaccinated, such as muscle aches or a raised temperature.
This is not the disease itself, but the body’s response to the vaccine.
