Earlier this week, the United Kingdom became the first country to grant emergency use to the Pfizer-BioNTech coronavirus vaccine, raising hopes that an end to the global pandemic, which has seen almost 65 million people infected and nearly 1.5 million deaths, might be in sight.

Neither vaccines can be injected in children and pregnant women.
Pfizer began testing its coronavirus vaccine in children up to 12. AstraZeneca, which is now undergoing a new global trial, has also committed to test its vaccine on children.
“If you have rare side effects, you want to find it on adults and not harm children,” Soumya Swaminathan, deputy director-general for programmes of the World Health Organization (WHO), told Al Jazeera.
Children have a more active immune system and can have a stronger reaction compared with adults. This can trigger the body to over-react to a vaccine and generate an inflammatory response.
